Bilateral Medial Tibiofemoral Joint Stiffness in Full Extension and 20° of Knee Flexion

摘要

Context:The valgus stress test is used clinically to assess injury to the medial knee structures in 2 positions: full extension and some degree of flexion. The amount of flexion used to “isolate” the medial collateral ligament is not consistent in the literature, but most studies have shown that stiffness of the ligaments was consistent between the limbs.
