Differential Diagnosis for Anterior Knee Pain

[@6williamson]

This was very nice. Not sure why it only had less than 500 views. Here is a good test. This anterior-lateral knee pain developed after a new 20 mile run. It is worse on hyperextension, medial to the ITB insertion, lateral to the patellar structures, worse on hyperextension, the pain is about 1 cm of point tenderness right at the joint itself, worse on hyperextension. Loading while flexed has no impact, twisting while standing slightly flexed no pain. No pain with palpation or manipulation of the patellar structures. A very good rheumatologist thinks its a lateral plica syndrome. After a month of rest, walking short distances doesn't cause pain, but running more than 50 feet, not so good, especially running downhill and during hyperextension. x-ray shows normal cartilaginous structures.

Thank you.

Palpation tenderness is often absent in patellofemoral pain or in patellar tendinopathy?
