39 years old, male, American
On 27-9-2020, he injured his right knee during playing basketball. On 8-10-2020, he took the first MRI, and the diagnosis was
Complete ACL tear
He started the Online Therapy with Jun Matsumoto from 17-10-2020 and continued Jun’s special rehab exercises for 6 months. The following two MRI pictures were taken on 17-04-2021.
In my experience, this is the first case of which the torn ACL healed in the abnormal position. The inferior remnant of the torn ACL attached not to the superior remnant but to the lateral wall of the notch or the medial aspect of the lateral femoral condyle in a position anterior and distal to the ACL anatomic footprint. I will follow up this case up to a year, and I will show here how this torn ACL changes its form finally. After 7 months from the injury, he can have normal daily activities, but still have a little pain on LCL.
