A Thessaly test performed with standing knee flexion is a reliable test for detecting what pathology?

• A. ACL tear
• B. Meniscal tear
• C. Patellofemoral pain
• D. Posterior horn tear

Answer: (B)

The Thessaly test loading the knee in a standing position stresses the menisci. With the knee flexed and the body rotated while compressed, a tear in the meniscal tissue catches between the femoral condyle and tibial plateau, provoking pain along the joint line or a locking/catching sensation. Performing the maneuver with standing weight-bearing and knee flexion increases load and rotational stress, which improves the ability to reveal meniscal pathology. This makes it a reliable indicator of a meniscal tear, rather than primarily indicating ACL injury, patellofemoral pain, or a posterior horn tear in isolation.
