Patellofemoral Disorders

Patellofemoral Pain Syndrome/Chondromalacia

1. Patellofemoral Grind Test:  The patient is supine with the knee relaxed as the examiner clasps the patella with their thumb and index fingers. The patella is then pressed against the medial and lateral femoral condyles.  A + test is pain and may or may not be associatedwith chondromalacia patellae.    There is very poor correlation between this test and chondromalacia.  One study showed a sensativity of 37%.
