ACL Tear Natural Healing Case Studies
Patient Information:
32 years old, male, Panamanian
Mechanism of Injury:
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.
ACL Tear (unclear stump (Ihara Classification IV))
Post-Injury Progress:
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.
