From what you've described, I agree with the probable diagnosis of anterior knee pain syndrome, or patella femoral syndrome. This is commmon in active adolescant females, and usually responds to non-surgical management, with physical therapy, bracing or taping, and NSAIDs.
For the few patients that do not respond to conservative treatment, surgery can be an option. Surgical procedures range from arthroscopic procedures, to large open procedures.
I have done PT, bracing and taken so many NSAIDs that they no longer work. Meloxicam didn't even make a difference. Mom doesn't want me to have surgery. Is there anything else I can do?
