@richtar Hello, over the course of a long and physical career, I had three lateral meniscus tears in my right knee. Each time I had orthoscopic surgery and they fixed it.
I did Physical Therapy, etc. and the only thing that worked was for them to go in and clean up the tear. They cut off pieces that were interfering with the joint action. They also removed any floating pieces of meniscus that were causing issues.
I do not regret the surgeries and would do them again. I put my first surgery off for years and it would feel better for a short time and then the pain would return.

While there might be differences of opinion on how to treat your knee, with the tear that you have, I’m not aware of anything being able to fix that surgery.
Wishing you the best!! Sherry
