I've had a problem with the lateral side of my knee for about 2 years now, and I can't get it to go away. Symptoms include moderate pain, and a popping sensation when the knee is bent, as if something is sliding in and out of place. It hurts most when squatting, and after 10+ mile runs. I can train normally, but the condition is always present.
My most recent thought is that it could be lateral plica syndrome. After some brief research, this seems to be a likely candidate. Has anyone ever experienced anything similar? If so, what was the actual diagnosis, and what did you do to treat it?
