Which test assesses the lateral collateral ligament (LCL)?

• A. Valgus stress test
• B. Varus stress test
• C. Posterior drawer test
• D. Mcmurray test

Answer: (B)

The varus stress test is the appropriate assessment for the lateral collateral ligament (LCL). This test involves applying a force that is directed inward toward the midline of the body while the knee is at 30 degrees of flexion. By doing this, the examiner can assess the integrity of the LCL, as any laxity or pain during this maneuver may indicate an injury to the ligament. In contrast, the valgus stress test is used to assess the medial collateral ligament (MCL) by applying a force outward. The posterior drawer test specifically evaluates the posterior cruciate ligament (PCL) by checking for posterior displacement of the tibia relative to the femur. The McMurray test is primarily aimed at detecting meniscal tears, rather than ligamentous injuries.
