Homer Simpson is experiencing lateral knee discomfort; which test would be most informative?

• A. Plantar fasciitis test
• B. Maximum elbow flexion
• C. Valgus overload
• D. Noble

Answer: (A)

Pain on the outer knee from repetitive motion is most often due to iliotibial band friction syndrome, and the Noble compression test is the best way to evaluate that specific issue. This test targets the IT band as it crosses the lateral femoral epicondyle; with the knee flexed to about 30 degrees, applying pressure there while moving the knee can reproduce the characteristic pain if ITB friction is present, making the test informative for this condition. The plantar fasciitis test is directed at foot pain from the plantar fascia, not the knee. The maximum elbow flexion test has no relevance to knee pathology. Valgus overload stresses the medial knee structures (like the MCL) and does not specifically assess the lateral IT band, so it’s less informative for lateral knee discomfort.
