What is the purpose of the Varus Stress Test?

The Varus Stress Test is specifically designed to assess ligament stability on the lateral aspect of a joint, particularly the knee. During the test, a force is applied to the outside of the knee while the joint is held in a slightly flexed position. This maneuver helps to evaluate the integrity of the lateral collateral ligament (LCL) and any other lateral stabilizing structures. If there is excessive laxity or gapping felt at the lateral aspect during the test, it may indicate a ligamentous injury on that side.

In contrast, other options focus on different aspects of joint assessment. The medial stability assessment or any evaluation of muscle strength and meniscus integrity involves different tests altogether. Understanding the specific application of the Varus Stress Test is critical for accurately diagnosing injuries that affect the lateral stability of the knee joint.
