Purpose
[edit | edit source]
The purpose of this test is to detect the presence of patellofemoral joint disorder (AKA: patellofemoral pain syndrome, chondromalacia patellae, patellofemoral DJD)
Technique
[edit | edit source]
Pt is positioned in supine or long sitting with the involved knee extended. The examiner places the web space of his hand just superior to the patella while applying pressure. The patient is instructed to gently and gradually contract the quadriceps muscle. A positive sign on this test is pain in the patellofemoral joint[1] .
Evidence[edit | edit source]
This technique is based on the mechanics of the patellofemoral joint and has not been specifically tested. Many patients will have pain with this test regardless of whether they exhibit signs and symptoms of patellofemoral pain[2] . Most of the clinical test for patellofemoral pain have low reliability or are untested, and there is no gold standard test for diagnosis of this disorder[3]. Since there is very limited specificity with this test, it should not be used alone to determine the presence of patellofemoral pain.
