Ive injured my lcl last two years..and now its getting bad and i have this sharp pain in my knee cap..what should i do?

Complex: The LCL is extremely complex. A tear often requires surgical reconstruction as it does not heal on its own. Knee cap pain is a separate and discrete issue. In your situation it may be best to seek out your nearest friendly neighborhood Sports Medicine Orthopedic Surgeon!

Unlikely an LCL: Likely a patellofemoral problem and not an LCL injury- see a fellowship trained sports med ortho surgeon who has high volume of sports knee injuries
