On October 19, 2022, during a soccer match, he twisted his right knee while attempting to tackle an opponent. A snapping sound was heard from his right knee when twisted. The next day, an MRI scan was performed, resulting in the following diagnosis.
Complete Tear of the Anterior Cruciate Ligament (ACL) of the Right Knee (the ligament ends separated (Ihara Classification III))
Progress After Injury:
After the injury, knee buckling occurred several times. After wearing a brace, no further knee buckling occurred. Rehabilitation exercises, including full knee extension, were started at a hospital in India. On November 3, an online consultation was started with Jun Matsumoto. The online treatment and at-home Evo-Devo Exercises were continued for 5 months, and a second MRI scan was performed on March 31, 2023.
MRI Results:
The torn ACL had regained its continuity and retained some degree of tension. However, the ligament at about one-third from the femoral attachment remained thin. (Ihara Healing Classification B)
Subsequent Course:
Subsequently, muscle strength training and range of motion recovery exercises were conducted, and he recovered to the point of living a normal daily life without issues. On November 3, 2023, one year after starting treatment, a third MRI scan was performed.
MRI Results:
The results of the third MRI were similar to those of the second one, with the ligament at the tear site remaining thin.
Discussion:
In this case, despite a complete rupture with separation of ligament ends, Evo-Devo Exercises allowed the continuity of the ACL to be restored, achieving natural healing. However, the healed form showed remaining thinning of the ligament, which raises concerns about the patient’s return to sports. Many doctors instruct early rehabilitation, including full knee extension, after ACL injury. In this case as well, the patient had started incorrect rehabilitation early. It is thought that the presence or absence of full knee extension exercises after injury can affect treatment outcomes, and we will continue to collect statistical data on treatment outcomes.
On August 21, 2022, during a basketball game, he felt a popping sound in his left knee when he jumped off his left foot. He could not move and was transported to the hospital. An MRI was performed the same day, leading to the following diagnosis. The Lachman test was positive.
From September 13, 2022, he began Natural Therapy with Jun Matsumoto through online treatment. He continued with online therapy and Evo-Devo Exercises at home, and after four months of treatment, a follow-up MRI was performed.
MRI Results:
Although the torn ACL did not regain enough tension, its continuity had recovered. Fibers near the femoral attachment were thin, but the distal part was sufficiently thick. (Ihara’s Healing Classification B)
Discussion:
This ACL tear had an unclear stump, a type of tear considered difficult to heal naturally (Ihara’s classification). Contrary to expectations, MRI taken five months after the injury showed that the continuity had been restored, yielding relatively favorable results. After continued rehabilitation, he recovered enough to perform daily activities without issues and could engage in light exercises like jogging.
On June 11, 2022, he twisted his right knee after a failed landing from a skateboard jump. An MRI was performed on June 25, and the following diagnosis was obtained:
Starting August 3, 2022, he began Jun Matsumoto’s natural therapy through the online sessions. He continued with online treatment and at-home Evo-Devo Exercises, and an MRI was performed five months after the start of treatment. The patient did not use any functional braces.
ACL tears in younger individuals often have unclear tear ends due to the softness of their fibers. This case also had unclear tear ends, making natural healing seem difficult. Additionally, the treatment started eight weeks after the injury, which also reduced the likelihood of successful natural healing. However, contrary to expectations, the ACL naturally healed with a thick and tense form. According to the Ihara Healing Classification, this is the highest grade, A. Unfortunately, during the treatment period, the patient sustained mild injuries to the medial and lateral meniscus. The patient was not wearing any functional braces, and I had not instructed him to do so. Considering such cases, starting from 2023, I have instructed all patients to wear braces.
On September 11, 2022, during a soccer match, an opponent collided with him from the left. At that time, he twisted his right knee unnaturally when he braced with his right foot. He went to the hospital the same day and had an MRI the next day, receiving the following diagnosis:
On September 15, he visited another hospital. The Lachman test was positive. On September 19, joint fluid was extracted through joint aspiration. After that, there was no swelling, and the knee could flex up to 90 degrees.
On October 3, he visited our clinic. Lachman test was positive, lever arm test was positive, and pivot shift was negative. He started Evo-Devo exercise therapy and continued it daily at home. Another MRI was performed on October 18.
Natural healing of the torn anterior cruciate ligament was confirmed. He continued the naturalization exercises, and MRIs were performed again on December 15 and January 19 of the following year.
The continuity of the anterior cruciate ligament was sufficiently confirmed, and the looseness was also improved.
Discussion:
The patient was a former top athlete in the Japanese national beach soccer team. He wished to continue playing soccer at a competitive level and frequently had MRI scans to closely monitor the healing process. Despite recommendations for surgery from doctors and all related soccer personnel, he chose natural healing, which was a bold decision. The healing level as per imaging diagnosis was Grade II four months post-injury. Although there were concerns about his return to high-level soccer, he underwent rehabilitation and returned to soccer after several months.
On August 20, 2023, during a soccer match, while dodging an opponent’s tackle while dribbling, he twisted his left knee. At that moment, he heard a tearing sound.
Post-Injury Course:
The next day, he visited a family doctor and it was determined that an MRI was necessary. He underwent an MRI on September 12, receiving the following diagnosis:
ACL complete Tear (proximal tear with retraction of the ends (Ihara classification III) Grade I MCL injury Grade I LCL injury
After the MRI, he continued functional recovery training instructed by a physical therapist for eight days. The prescribed exercises included an exercise bike, knee extension exercises, and squats. From September 23, he began the online therapy online with Jun Matsumoto. On December 27, he had his second MRI scan.
Based on the MRI images, the torn ends had adhered to the PCL. On December 28, he had an in-person consultation in Hong Kong where both the Lachman test and pivot shift test were both negative. Subsequent MRIs were performed on February 2 and April 27 of the following year.
According to the radiologist’s opinion on the MRI from April 27, the torn ACL displayed a loose and weakened structure with ligament fiber reconstruction. On May 4, the patient resumed playing soccer but heard a painless tearing sound when he slipped during play.
Discussion:
The outcome of this case was deformity healing with adhesion to the PCL. Two possible causes for the deformity healing are proposed. One is that not only were the torn ends separated, but they were also unclear. The other is that rehabilitation for surgery had already been implemented before starting the natural healing therapy. Exercises involving full knee extension are considered to hinder natural healing. In the future, we plan to compare the healing results between groups that performed full knee extension exercises and those that did not.
On March 7, 2022, while skiing, she fell with her right ski stuck in the snow.
Progress after injury:
She was taken to an emergency hospital on the day of the accident, where X-rays showed no fractures. The next day, she visited a local orthopedic clinic, where joint fluid was removed through aspiration. An MRI on March 15 revealed the following diagnosis:
Complete ACL tear of the right knee (proximal 1/3 tear with separation of the torn ends, classified as Type III according to Ihara’s classification).
From April 18, 2022, she started online therapy with Jun Matsumoto. She received regular online treatments for four months, and a follow-up MRI was conducted on August 17. During this period, she did not wear any functional braces.
The second MRI did not show clear healing of the torn ACL. However, the tension in the tibial side suggested possible healing at a non-original location. Therapy continued, and a third MRI was conducted on November 11.
The third MRI also did not show clear natural healing of the torn ACL. However, a comprehensive examination of the sagittal and coronal images suggested that the tibial end had healed to the lateral wall of the intercondylar notch. Online treatment was stopped, and PRP injection therapy was started. Another MRI was conducted on August 31, 2023.
Since the ACL had already healed to the lateral wall, natural healing to its original location could not be confirmed.
Discussion:
In this case, the torn ACL could not heal naturally in an ideal manner. The result was a deformed healing to the lateral wall of the intercondylar notch. Functionally, the knee joint was stable, and the patient reported no issues in daily life. Despite not recommending braces for this patient, braces are now recommended for all subsequent patients.
Age: 13 years Gender: Female Nationality: Japanese
Mechanism of Injury:
Date of Injury: June 10, 2023 Details: Twisted the left knee during a practice basketball game.
Progress after injury:
MRI Date: June 12, 2023 Diagnosis: Complete rupture of the left anterior cruciate ligament (ACL) with curved ends (Ihara Classification II).
Despite fresh trauma being confirmed by imaging, the patient had felt the knee dislocate several times over the past two years, but these symptoms quickly resolved each time. No joint fluid was aspirated during the examination. Post-injury, there were no knee collapses. Without undergoing hospital rehabilitation, the patient started our natural therapy on June 24, 2023, continuing for four months. A follow-up MRI was performed on October 25, 2023.
Results:
The second MRI showed no signs of natural healing of the ruptured ACL.
Discussion:
In this case, natural healing was not observed, and there was minimal deformity or adhesion to other structures like the posterior cruciate ligament. Despite having a tear pattern that typically allows for natural healing, the exact reasons for the failure remain unclear. Two potential reasons are: 1. Research indicates that younger females have a lower success rate of natural ligament healing compared to adults or males of the same age. 2. The issue of commuting to school. Although advised to avoid long-distance walking or cycling, family circumstances sometimes prevented this. Thus, the patient was not always able to avoid these activities. Future improvements in treatment methods and living environments are necessary to enhance healing rates in younger patients.
On January 6, 2023, while skiing downhill, she fell on an ice slope and fell down. She was unable to stand up and she was rescued by rescue teams.
Progress after injury:
She returned to Hungary from Slovakia, where she consulted an orthopedic surgeon. She had her joint fluid removed by arthrocentesis. She had an MRI done on January 9th, and she received the following diagnosis.
On January 16th, she visited the orthopedic surgeon again. The Lachman test was positive. She then began range of motion exercises, including full knee extension.
On January 20th, she started online therapy with Jun Matsumoto and began Evo-Devo Exercises.
On February 17th, she had another MRI scan. The images were taken with the knee fully extended. The latest MRI images did not confirm her spontaneous recovery. In fact, the distance between the stumps had widened and worsened. The tibial stump remained in a displaced position and had not improved.
After that, she continued Evo-Devo Exercises and had a third MRI scan on May 18th.
Spontaneous recovery was not confirmed in this MRI scan, but the Lachman test conducted by the doctor showed negative result. She then discontinued Evo-Devo Exercises and started physical therapy in Hungary. On September 18th, her fourth MRI was performed.
This MRI showed no major changes. The patient had limited range of motion in his right knee and had residual knee dysfunction. He is continuing exercise therapy to improve his functional impairment. The fifth MRI was performed on February 27, 2024.
The diagnostic imaging specialist’s report determined that the ACL was torn, but that some of the fibers were still connected. Although the patient is able to lead a normal daily life, she still has limited range of motion in his right knee and is currently undergoing physical therapy.
Consideration:
In this case, not only did the torn ACL not heal well, but there was still clear functional impairment, and natural healing could be said to have failed. There are four possible causes of failure. The first is that the distal end of the stum had turned over, making it difficult for it to heal naturally. Second, blood had been removed by arthrocentesis. Third, physical therapy including full extension was performed early after the injury. Fourth, a second MRI was taken in the fully extended position early after the injury. Based on these results, we would like to strive to improve future treatment methods.
On November 3, 2022, during a beach ball volleyball game, when she landed on his left foot after an attack, her ipsilateral left knee twisted and she collapsed.
Progress after injury:
After her injury, she received treatment including electrical therapy at another orthopedic clinic. She visited an orthopedic surgeon on November 21st, and X-rays were taken, but no fractures were found. At this time, she had her synovial fluid removed with an arthrocentesis. She had an MRI scan on November 26th, and she received the following diagnosis.
She started online treatment with Jun Matsumoto on December 3rd and continued her Evo-Devo Exercise therapy three times daily at her home. She had a second MRI scan 4 months after starting treatment. She still did not wear her functional brace on a daily basis.
Follo-up and Outcomes
Her MRI images showed no clear connection between the stumps of her torn ACL. Her distal ACL stump was connected with the PCL. At this time, her doctor’s evaluation of the Lachman test was negative.
She then performed range of motion exercises and strength training, and her condition recovered to a level where she had no problems in her daily life. She gradually returned to playing beach ball in July of the same year. When she played, she twisted excessively to her left and felt instability in her knee, so she played with tape and a brace on.
On July 30th, while she was playing beach ball, she twisted her left knee again. Her knee was swollen for several days, so she was kept on bed rest.
On October 9th, Jun Matsumoto met with the patient and performed a manual examination. He had a pivot shift test (±) and a Lackman test (-).
On December 9th, her third MRI was performed. Her third MRI image showed no major changes compared to the second, suggesting that its morphology remained fixed as the degenerative healing.
Consideration:
In this case, the patient had been treated and supported for about a year, but the expected results were not obtained. I hypothesized that there were three causes that led to this deformity healing. The first is the removal of blood and edema by arthrocentesis. Second, she did not wear a functional orthosis on a daily basis. Third, the rupture pattern of the ACL was unclear, making it difficult for it to heal naturally. After this case, the later patients were instructed to wear a functional orthosis.
On July 21st, 2022, he was playing badminton. When he put his right foot forward to pick up the shuttlecock that was falling in front of him, he fell to his right side. He went to the hospital but was not referred for an MRI immediately. No joint fluid was extracted through knee arthrocentesis. He underwent acupuncture several times and participated in two weeks of physiotherapy, including knee extension. On September 8, he was scanned for the MRI and diagnosed as:
a complete ACL tear (ruptured at the proximal part, classified as type I, in which the torn ends are facing each other) MCL sprain Lateral meniscus tear
Starting September 17, 2022, he engaged in Evo-Devo Exercises with Jun Matsumoto, continuing for three months without wearing a functional knee brace restricting the range of motion. On May 9, 2023, he was scanned for the second MRI.
MRI evaluation:
The torn ACL had degenerated and no clear continuity could be confirmed.
Consideration and reflection:
Even though the type of the ACL tear is easier to heal naturally, the expected healing failed. There are three possible causes. The first was that he did not wear a functional brace. Second, treatment started two months after the injury, which was relatively late. Third, before starting treatment, physical therapy with full knee extension was performed. Based on this failure, future treatment plans will likely be reconsidered.
On April 4, 2022, the patient was playing football when he experienced a twisting and collapsing incident involving his right knee. An MRI was performed on the same day.
Diagnosis:
Primary Diagnosis: Complete tear of the Anterior Cruciate Ligament (ACL), specifically in the middle part, classified as Type 2.
Secondary Observations:
The meniscus showed no signs of damage.
A slight damage was noted in the Posterior Cruciate Ligament (PCL).
Treatment:
The patient commenced online sessions with Jun Matsumoto on May 10, 2022. The treatment plan involved a specific set of exercises known as “Evo-Devo Exercises.” During this therapy, the patient was instructed not to engage in any other forms of exercise. Additionally, he did not use a knee brace during the course of his treatment. After three months of the treatment, he took the next MRI.
MRI evaluation:
In the patient’s subsequent MRI, the healing of the ACL fibers did not progress as anticipated. The fibers appeared thin, and the condition was classified as Grade III. (Ihara’s ACL healing classification) During the Lachman test, the knee’s instability was rated as 2 out of 3. However, there was a positive note in that the quadriceps muscle showed signs of recovery. Given these mixed results, it was decided to continue with the conservative therapy approach.
Accident:
On November 8, 2022, despite his father’s advice against it, the patient began playing basketball. Approximately 15 minutes into the game, he suddenly heard a clicking sound in his knee, followed by severe pain, which led him to stop playing immediately. Subsequently, his knee became swollen. An MRI taken on November 27 showed that there was no complete tear of the ACL, and no significant changes were observed from the previous MRI results.
ACLR surgery:
Given the patient’s young age, the remaining instability in the knee, and the fear of reinjury, the decision was ultimately made to proceed with ACL reconstruction surgery. This choice was influenced by the need for a more stable and definitive solution to ensure the patient’s long-term knee health and functionality.
Consideration and reflection:
The approach of not using a knee brace during treatment raises questions about its impact on the healing process. Additionally, the patient’s early return to playing basketball, which resulted in the accident, suggests the need for a more cautious approach to resuming sports activities post-injury. These aspects highlight the necessity for further study and evaluation of treatment protocols.
Japanese, female, 40 years old On Nov.12th, 2022, she did a jumping kick during kickboxing practice and twisted when she landed on her left foot. She continued her practice for about an hour right after that. She felt her knees give way.
On Nov.21st, she took the first MRI, but the old MRI didn’t show the good resolution for diagnosis. On Dec.6th, she took the second MRI, and it indicates:
Partial tear of ACL
She didn’t feel any problem in having the normal daily activities. She didn’t feel giving way on the knee. However, the injured knee was a bit loose through the anterior drawer test. Therefore, she stopped not only practicing kickboxing but also stopped any other form of exercise. Not only that, but she stopped fully extending her knees.
Starting Dec. 7th, she initiated online therapy with Jun Matsumoto and continued Evo-Devo Exercises for five weeks. On Jan. 16th, 2023, the third MRI scan was performed.
MRI indicates:
The fibers, which had become sagging due to partial rupture, regained their tautness and straightness.
Future Prospects and Considerations:
Despite only five weeks of treatment, her injured anterior cruciate ligament achieved spontaneous healing. The reason was that the anterior cruciate ligament was partially torn, not completely torn. Another reason may be that the injured ligaments were not separated from each other. With proper treatment, patients with partial anterior cruciate ligament rupture are likely to be able to return to normal daily activities or return to sport earlier than cases with complete rupture.
Japanese female, 41 years old. On July 5th, 2022, she experienced a sensation of her right knee dislocating while exerting force on her right leg during a basketball game, rendering her immobile. Although she was able to walk later, she visited a hospital two days after the incident. No joint fluid was aspirated during the examination. An MRI scan was performed on July 12th, revealing the following diagnosis:
Complete right Anterior Cruciate Ligament (ACL) tear (proximal 1/3) No meniscal damage.
According to the Ihara’s ACL tear classification of ACL injuries, it was classified as a type 2, which is the torn and disrupted type. After the injury, no giving way of the knee was reported. She did not undergo any physiotherapy involving knee extension post-injury. She had a history of a left Achilles tendon rupture surgery 13 years prior.
Starting July 28th, she initiated online therapy with Jun Matsumoto and continued Evo-Devo Exercises for five months. On December 12th, 2022, a second MRI scan was performed.
MRI indicates:
The evaluation of the MRI images indicated that the ruptured anterior cruciate ligament had restored continuity and healed naturally. According to Ihara’s ACL healing classification, it was classified as grade 3, which is thinned healed fiber.
Future Prospects and Considerations:
Having confirmed natural healing through MRI, she initiated full knee extension training and strength training. By the six-month mark post-injury, she had recovered to a level where she faced no issues in daily life. She is currently undergoing further rehabilitation with the aim of returning to recreational-level sports.
37 years old, Female, Kazakh living in the U.S. On February 26th, 2022, he twisted her left knee during skiing. She went through the MRI scan, and the diagnosis was:
Complete ACL tear
According to the Ihara’s classification, this type of ACL tear is classified as disrupted or unclear type. And, this type has been reported as the most difficult type to heal spontaneously.
After the injury, she had been doing some rehabilitation exercises such as strengthening the muscles and 10 min stationary bike under the supervision by a physiotherapist.
On April 29th, she started the Evo-Devo Exercises through the online sessions with Jun Matsumoto, and continued the sessions only for two months. During these months, she stopped doing any strength trainning and focused on the Evo-Devo EXercises. After doing two momths, she started strength training again.
On November 18th, she took the second MRI as poseted below.
MRI indicates:
The MRI shows the clear continuity of the ACL. This healing type can be classified as grade I of the Ihara’s classification, and it is the taut and straight band type of healing.
Future prospects and considerations:
Even though this type of ACL tear has been reported as the most difficult type to heal spontaneously, it has heald upto the best type of healing.
25 years old, Male, Indian On April 13th,2022, he twisted this right knee during playing soccer. On April 15th, he went through the MRI scan, and the diagnosis was:
complete ACL tear tear of the anterior root of the lateral meniscus mild grade1 tear of the body of the medial meniscus sprain of the mecial and lateral collateral ligaments
complete ACL tearmedial meniscus tearanterior root tear of the lateral meniscus
On May 24, he started the Evo-Devo Exercises through the online session with Jun Matsumoto. He had four online sessions in a month, and after that he continued the Evo-Devo EX by himself for three months. On October 2nd, he took the second MRI.
healing into the taut and striaight bandmedial meniscus tear remainsanterior root of lateral meniscus remains
MRI indicates:
It can be seen that the completely torn ACL grows into the taut and straight band. And, this morphological type of healing is classified as the type 1 by Ihara’s classification. Although the ACL has been healing into the best morphology, the meniscus tears still remain and have even deteriorated further.
Future prospects and considerations:
Regarding to horizontal tear of meniscus, it could be asymptomatic in many cases. However, it is, of course, better to be healed than not to be healed. There is a need to improve existing treatments to make it heal the unhealed meniscus tears.
55 years old, female, Japanese On March 7th, 2022, she fell in the snow while skiing. And, then her right ski stuck in the snow, and her body was pushed forward. She was immedeately taken to the hospital and scanned for x-ray, but there was no fracture. At that time, the blood and the fluid in the right knee were extracted by the doctor. One week later, she was scanned for MRI, and the diagnosis was:
Complete ACL tear No other ligament tear Bone contusion on posterior tibia
On April 18, she started the Evo-Devo Exercises through the online session with Jun Matsumoto. Since the injury, she did not experienced knee giving way. She continued the Evo-Devo EX. for four months, and she took the second MRI.
The second MRI did not show the clear natural healing of the torn ACL even though she did not feel the instability of the knee any more. She continued the exercises and took the third MRI at the different hospital to have more various pictures.
MRI indicates:
The MRI above doesn’t show the clear continuity of the ACL, however, the middle one shows the clear continuity. It is not the clear and beautiful natural healing, but it is sure that the torn ACL acquired the continuity to stabilize the knee. The MRI below is the one of the coronal slices taken on the same day 2022/11/11. It shows that the ACL is morphologically deformed and does not adhere to the original position. That may be the reason why the MRI in sagital plane does not project the clear continuity.
Future prospects and considerations:
Even though the MRI does not show the expected beautiful healing, the torn ACL finally acquired the continuity. She will try the PRP injection to expect the further natural healing. If the platelet contains the self-healing substances, the blood and the fluid in the knee should not be extracted by injection just after the injury. This ridiculous treatment might have interrupted the natural healing. In the functional meaning, her right knee healed well without feeling any instability, and she already has the normal daily activities.
After PRP injections:
She tried the PRP injections for three times and took the MRI again on Aug.31st, 2023. The slight progress of the ACL healing can be seen on the sagittal plane. At this time, Lachman test was performed, and the result was negative. Her prognosis is relatively good, and she is having a normal daily life.
44 years old, Male, Japanese On April 9th,2022, he was practicing Judo and trying to throw the opponent. Then, his left knee was twisted internally, and he collopsed down to the ground. He went to the hospital, and Lackman’s test was positive. When he turned the direction, he had gaving way syndrome. He took the MRI on April 19th, and the diagnosis was:
Complete ACL tear MCL tear
He didn’t want to have a surgery, and he was searching the alternative treatment. He found the Natural Healing Therapy by Jun Matsumoto, and he started the online therapy with him from May 24th, 2022. He had the weekly sessions with Jun and continued doing the Evo-Devo Exercises for five momths. He took the second MRI on October 18th.
The MRI indicates:
The MRI shows the continuity of the ACL. His doctor diagnosed this case as the spontaneous healing of the ACL tear. There was still some signal intensity on the MCL.
Future prospects and considerations:
Jun Matsumoto allowed him to start doing more intense exercises such as squatting and lunge. On November 17th, he got drunk and twisted the left knee again. he says that it wasn’t a serious inury though. Let’s see and follow his prognosis from now on.
8 years old, Male, Japanese On Nov.30, 2021, he injured his left knee by his own movement during playing soccer. On the same day, he was taken to the hospital and scanned through the x-ray. On Dec.11, 2021, he was taken through the MRI scanning, and the diagnosis was:
ACL Tear Suspected Avulsion Fracture of tibial spine
His doctor said that he was too young to have the ACL reconstruction as there is a high risk of interfering the bone growth. On Jan.18, he and his family visited Jun Matsumoto and started the Evo-Devo EX. for natural healing of the ACL tear. The Lackman’s test was positive. He continued the Evo-Devo EX. through the face-to-face and online sessions. The next MRI was taken on Mar.30.
Even though the MRI pictures don’t show the clear continuity of the ACL, the Lackman’s test was negative at that time. After continuing the Evo-Devo EX. furthermore, he took the third MRI on Aug.17.
The MRI indicates:
Even though the T1 pictures don’t show the clear appearance of the natural healing, the T2 picture(the first one pf 08/17) shows the continuity of the ACL.
Future prospects and considerations:
Due to the poor resolution of the 1.5T MRI, it is difficult to have the exact diagnosis from these MRI. However, from the results of MRI and Lachman’s test, it can be inferred that the ACL healed spontaneously. Around 10 months from the injury, he already recovered the full range of motion of the knee, and started attending the physical education class at school. After one year from the injury, he plans to return to playing soccer.
59 years old, Male, Japanese On Dec.28, 2021, he injured his right knee during skiing. On the same day, he was taken to the hospital, and there was no fracture through x-ray. On Jan.13, he was taken to the MRI scanning and diagnoses as:
Complete ACL tear Buckling of medial meniscus
On Jan.17, he had a surgery for repairing the meniscus, and his knee was immobilized by the cast for three weeks. After the cast was removed, he visited Jun Matsumoto, and he started the Evo-Devo EX. for natural healing of ACL tear. He continued the therapy through face-to-face and online sessions for six months. On August 4, he took the next MRI.
The MRI indicates:
Continuity of ACL fibres
Future prospects and considerations:
In my experience, this is the first case of natural healing of ACL tear after the meniscus repair surgery. I assumed that natural healing would be immpossible, becasue the knee was immobilized for three weeks. Actually, it took a long time to recover the range of motion due to the contracture after the immobilization. Contrary to my assumption, the torn ACL has successfully healed naturally after 6 months of the Evo-Devo EX.. After the natural healing was observed through the second MRI, he started strength trainning as well as Evo-Devo EX. to return to skiing. In October, he already has the normal dialy activities without problem and continues the rehab exercises every day.
45 years old, Male, Japanese He injured her right knee during skiing on February 5th, 2022. On February 10th, she went to the MRI scanning, and the diagnosis was:
Complete ACL tear MCL tear grade2
On February 21, 2022, he started the online therapy for the natural healing of the ACL tear with Jun Matsumoto. He continued doing Evo-Devo Exercises for six months, and he took the next MRI on August 17th, 2022.
The MRI indicates:
Visible continuity of the ACL
Future prospects and considerations:
According to the new MRI, the visible continuity of the ACL can be seen, even though it is not the perfectly clear one. This morphological healing is classified as the type II of Ihara’s classification, and the healed ACL is the straight band with partial thinning. The patient has healed functionally very well, and he doesn’t feel any pain in the daily activities so far. He will continue the Evo-Devo Exercises and the some strength exercises until he can return to skiing.
41 years old, Female, American She injured her left knee during skiing on February 4th, 2022. On February 10th, she went to the MRI scanning, and the diagnosis was:
Complete ACL tear
On February 27, 2022, she started the online therapy for the natural healing of the ACL tear with Jun Matsumoto. She continued doing Evo-Devo Exercises for four months, and she took the next MRI on July 5th, 2022.
MRI reports:
Modest signs of suffering are detectable in the anterior cruciate ligament which appears slightly reduced in thickness in the middle-distal III with an inhomogeneous signal that tends to be hyperintense in the T2-weighted sequences for slight edematous imbibition with characteristics compatible with the outcomes of a “strain” suffering with probable parcel laceration and persistence of a tenuous edematous suffering of the residual ligament; the ligamentous structure however remains clearly visible along its entire course with modest surrounding synovial thickening and periligamentous liquid layer in the distal insertion tract.
Future prospects:
According to the report above, the torn ACL starts healing naturally, and it will take a while until healing process ends. Jun Matsumoto permitted her to practice the full range of motion of the affecyed knee and start strengthen the quadriceps muscles. Even though she still feels weakness on the affected knee, there is no othere complication in her daily life activities. Further more, she will contines the Evo-Devo Exercises and strength exercises until she gets ready to return to skiing.
32 year old, male, Romanian He injured his right knee during practicing Jujutsu on November 22th, 2021. Four days later, he went to the MRI scanning, and the diagnosis was:
Complete ACL tear
On February 25, 2022, he started the online therapy for the natural healing of the ACL tear with Jun Matsumoto. It already has passed for three months from the injury, and it was assumed that the natural healing could be difficult. He understood the difficulty, but he continued doing Evo-Devo Exercises for three months, and he took the next MRI on May 26th, 2022.
The MRI indicates:
Certainly visible continuity of the ACL
Future prospects and considerations
This is a remarkable case of natural healing of ACL tear because it already had passed for three months from the injury at the time of when he started the natural therapy. There was no other ligamentous or meniscus injury, it is assumed that he can retrun to the sport after further rehab exercies.
34 year old, male, Filipino living in Japan He injured his right knee during playing Baskaetball on October 24th, 2021. When he changed the direction by loading this weight on the right knee, he twisted the right knee, and he fell down. One week later, he went to the MRI scanning, and the diagnosis was:
Complete ACL tear Lateral Meniscus tear
On November 11, 2021, he started the face to face therapy for the self healing of the ACL tear with Jun Matsumoto. He continued doing the Evo-Devo Exercises for five months, and he took the next MRI on April 30,2022.
The MRI report indicates:
Minor tear on ACL but there is the continuity. Lateral Meniscus tear
Future prospects:
Even though the lateral meniscus still remains, the torn ACL has almost healed naturally by its own. Jun Matsumoto ordered him to spend the normal daily life activity without doing any sport for a few months. They agreed to see how it works later. If the unhealed meniscus impairs the knee in the future, the option for the surgery can be taken.
37 year old, male, Australian living in Austria He injured left knee while rock climbing on the 3rd November 2021. He fell akwardly from a very low height and his weight went on my knee in a bad direction. Two weeks later, he went to the MRI scanning, and the diagnosis was:
On December 8th,2021, he started the online therapy for the natural healing of the ACL tear with Jun Matsumoto. He continued doing the Evo-Devo Exercises for four months, and he took the next MRIs on April 25,2022.
The MRI report indicates:
“Regular positioning of the patella in the femoropatellar compartment, the retropetallar cartilage shows a deep cartilage ulceration at the medial facet, which is slightly increasing compared to the previous examination, reaching the cartilage-bone lamella. The trochlear cartilage is continuous. The medial and lateral retinaculum patellae are unremarkable.
Infrapatellar fat body in regular formation. In the lateral femorotibial compartment ubiquitous cartilage cover, the lateral meniscus shows a circumscribed linearity at the posterior horn IMA 8-27, this was already present in the previous examination, but currently appears somewhat expanded and reaches the tibial meniscus surface.
In the medial femorotibial compartment there is a cartilage cover throughout, the medial meniscus at the posterior horn appears clearly more elevated than in the previous examination, but there is no evidence of a dislocated meniscus fragment.
The posterior cruciate ligament is continuous. After rupture of the anterior cruciate ligament, the latter is still edematised, but individual fibrous strands show signs of continuity.
Significant decrease in knee joint swelling. Angelegte Baker-Zyste. Baker’s cyst in place. Typical flow-void popliteal.”
Future prospects
Even though the meniscus tears still remain unhealed, the torn ACL is successfully healing naturally. Jun Matsumoto ordered him to start strengthening the leg muscles, and agreed to follow-up the further prognosis.
31 year old, male, Japanese On September 20th, 2021, he was playing badminton, and when he landed on his left knee from jumping, he twisted it. Two weeks later, he went to the MRI scanning, and the diagnosis was:
Complete ACL tear Tear of the posterior segment of the Medial Meniscus Tear of the posterior segment of the Lateral Meniscus
On October 28th,2021, he started the online therapy for the natural healing of the ACL tear with Jun Matsumoto. He continued doing the Evo-Devo Exercises for four months, and he took the next MRIs on February 25,2022.
The MRI report indicates:
Partial ACL tear
By comparing the MRIs of 2021/10/05 and 2022/02/25, the torn ACL starts healing spontaneously and growing intact. The torn ACL is still in healing process. However, the both meniscii tears remain unhealed yet at this moment. Jun Matsumoto ordered him to continue doing he Evo-Devo EX until the continuation of the ACL becomes more firm. The patient recovered the full range of motion of the left knee, and he doesn’t feel any instability of the knee. He can walk normally and have the normal daily activities so far.
Evolutionary and Developmental Exercises Seminar will be held in Tokyo. In this seminar you can learn the essences of Evo-Devo Exercises step by step. Evo-Devo Exercises are the name of the exercises which are based on the evolution and the development of human beings. Many of the musculoskeletal disorders are caused by the lack of the development movements during 0-year old age. In this seminar, you will learn:
Learn the 0-year old exercises precisely, and why those are important for our healthy life.
How to overcome musculoskeletal disorders by Evo-Devo Exercises approach.
How to improve physical abilities by Evo-Devo Exercises.
Evo-Devo Exercises involve all of the body parts and let them move with natural coordination. As you complete all of the exercises, you will retrieve natural body and movements.
Tokyo seminar
Date: May 22, 2022 class 1: 13:00-14:50(110 min.) class 2: 15:00-16:20(80 min.) class 3: 16:30-17:50(80 min.)
12 years old, male, Indian On September 20th, 2021, during leg curl strength test due to carelessness of the doctor, his right knee got injured. Mri report indicates:
complete tear of the proximal segment bundle of the acl. Grade 3 sprain is also seen involving proximal segment and femoral attachment with increased signal. Tbl attachments /pcl are intact. Intact collaterals, posteromedial and posterolateral corners, menisci.
On October 22nd,2021, he started the online therapy for the natural healing of the ACL tear with Jun Matsumoto. He continued doing the Evo-Devo Exercises for four months, and he took the next MRIs on March 2nd,2022.
The MRI report indicates:
Proximal segment of the anterior cruciate ligament appears vertically oriented flush with the medial aspect of the lateral femoral condyle and shows iso to slightly hyperintense signal on both T1 and T2-weighted images. Intact tibial attachments of both anteromedial and posterolateral bundles.
Although some tissues of the torn ACL are growing intact to the medial aspect of the lateral femoral condyle, the proximal femoral attachment is intact. Spontaneous healing of the torn ACL is occuring on the new MRI, and Jun Matsumoto permitted him to start doing more intense exercises so that he could retrun to playing the tennis.
He is the youngest patient who spontaneously healed from the ACL tear by Evo-Devo Exercises. In most cases, the surgeries for patients in chilhood are avoided because of the risk of imparing their bone growth. There has not been any appropriate medication for juvenile patients with ACL tears. The Evo-Devo Exercises can be the hope for the patients in childhood, and more successful cases can be accumulated and studied.
22 years old, male, Japanese On August 21, 2021, while practicing soccer, he was about to collide with an ally and twisted his left knee when he stepped on with one of his left feet. He underwent a (non-contact) orthopedics and underwent an MRI scan on August 25, and was diagnosed with anterior cruciate ligament rupture.
From October 2, 2021, he started the natural healing therapy with Jun Matsumoto. After continuing exercise therapy based on evolutionary developmental biology called Evo-Devo Exercises for 4 months, a new MRI image was taken.
MRI indicates:
The continuity of the torn anterior cruciate ligament was confirmed, and it was also confirmed that it healed spontaneously. Jun gave him the permission for jogging and strength training and said he could return to sports as soon as he was in good condition.
21-year old, male, college rugby player, Japanese On Myay 12th, 2021, when he wa playing rugby, he twisted his right knee on his own. He went to the hospital, and his knee was scanned for the MRI. The diagnosis was the ACL complete rupture.
Complete rupture of the ACL
On May 15th, he started the therapy for the natural healing of the ACL tear through the online session with Jun Matsumoto. He continued doing the Evo-Devo Exercises for four months, and he took the next MRIs on September 22nd.
spontaneous healing was confirmed
MRI indicates:
The MRI picture shows that the ACL is anatomically intact and the ruptured ACL healed naturally. He is functionally moving well, and Jun Matsumoto permitted him to increase the intensity of the exercises. After completed the athletic rehabilitation for three months, on December 26th, he came back the game in the national college championship, and made a nice try.
46-year old, Female, Japanese On August 30, 2021, when she was practicing Jujutsu martial arts, she twisted her left knee. She went to the hospital, and her knee was scanned for the MRI. The diagnosis was: ACL complete tear
On September 20th she started the therapy for the natural healing of the ACL tear through the online session with Jun Matsumoto. She continued to do the Evo-Devo Exercises for three months, and she took the next MRIs on December 21st.
MRI indicates:

72-year old, Male, Japanese On May 1st, 2021, when he was climbing the mountain, he stepped off and fell down. On the same day, he was taken to the hospital, and his right knee was scanned for the MRI. The diagnosis was:
Complete ACL tear
On May 14th he started the therapy for the natural healing of the ACL tear through the online session with Jun Matsumoto. He continued to have the session once a week for 4 months. On May 14th he started the therapy for the natural healing of the ACL tear through the online session with Jun Matsumoto more than one hour every day. Because of his age, it was doubtful that the torn ACL would heal spontaneously. But, he never used his age as an excuse. He went to the hospital and took the new MRI 4 months from starting the natural therapy. Fortunately, it was found that the torn ACL were healing naturally and had its continuation. Jun permitted him to do the more intense exercises. This man hopes that he can climb the mountain again, and Jun will continue to help him.
16-year old, Male, Japanese On March 21st, 2021, he twisted his left knee by his own movement during playing the handball. Next day, he was taken to the hospital, and his left knee was scanned for the MRI. The diagnosis was:
ACL complete tear Medial meniscus tear
He visited Jun Matsumoto`s Natural Therapy Office, and started the evo-devo exercises for the natural healing of the ACL tear. He has visited there once a week for 4 months and has continued the exercises every day at home. He took the MRI at the different hospital on September 4th, and it was found that the torn ACL was healing naturally. Jun Matsumoto permitted him to do jogging and start the more intense exercises. In next 3 months, he will return to playing the handball in athletic level.
The torn ACL grows intact.
When he was running on September 28th, he twisted my left knee again. On the same day, he underwent an MRI scan at the hospital and was diagnosed with anterior cruciate ligament rupture. After several days of rest, he resumed
