Hard to say: While the pain on flexion can be something as simple as some degenerative changes on the back of the patella. It needs to be evaluated further for a specific diagnosis is there an effusion or swelling preventing the motion or is there some internal derangement such as a meniscal tear, loose body or ligamentous injury.
