I was an active 68-year-old until a body boarding accident created issues with both knees. I likely exacerbated my issue by continuing to mountain bike. My left knee had meniscus tears and stage 2 to 4 OA, a burst Baker cyst that blackened my leg from the ankle to the hip. After rehabbing that knee six weeks my right knee blew up to three times its size. an MRI determined meniscus, tears, and some OA, but both the PT and orthopedic surgeon could not make a solid diagnosis. When a wave hit me bodyboarding, it hit on the left knee which forced the bent left knee in and the right bent knee out. For several months I have had instability in that my fibula pops out. This causes great pain and I am in mobilized until it slips back in. I have tried describing this to both PT and orthopedic surgeon. I think there is some eye rolling because of my age. It’s extremely frustrating I took it upon myself to research my symptoms. I came across a video done by Ben, knees, over toes guy, where he describes proximal to fibula joint instability what he describes is exactly what I am experiencing except with pain. I know this is an older video but I would be most interested in knowing the outcome of the young woman with this condition. Was she able to rehab through PT or did she end up having surgery? Thank you for this information.

As a person suffering with this injury, I wish the author would state if patients should find a doctor who can use ultrasound to help with the problem. It is my understanding this did not lead to the patient healing through further treatment.

Thank you for sharing. Very informative. I see bone bruising on sagittal and coronal images in the region of proximal TF joint in the MRI from 2021. It was resolved in 2022. I did not see the axial images from 2021. What is the sensitivity of MRI for diagnosing the tear/sprain of anterior and posterior Prox TF ligaments ?. Was that evident on the MRI from 2021? If it was then a physical examination after that can demonstrate more laxity of the affected joint since it was already wider in the neutral position. But I would agree that a good MSK US done before an MRI in such cases can point towards this diagnosis since we can scan both knees in the office.
