The PFJ Compression Test performed in standing primarily indicates which pathology?

• A. Patellofemoral provocation test
• B. Knee osteoarthritis
• C. Meniscal injury
• D. Patellofemoral pathology

Answer: (D)

The maneuver directly tests the patellofemoral joint by pressing the patella into the femoral trochlea. If this standing compression reproduces anterior knee pain, crepitus, or grinding sounds, it points to pathology at the patellofemoral joint—such as patellofemoral pain syndrome or related patellar surface issues. It’s not primarily a test for meniscal injury, which usually causes joint-line or rotation-related pain, nor is it a general test for knee osteoarthritis, which tends to present with broader joint symptoms and radiographic changes. A patellofemoral provocation test is a related concept, but the specific patellofemoral compression test in standing best indicates patellofemoral pathology.
