Spontaneous Healing of a Complete ACL Tear in children -case 15

ACL Online Therapy for natural healing

ACL tears heal without surgery

Patient information:

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.
