varus stress test
Clinical examination maneuver applying inward angulation force to assess lateral collateral ligament integrity.
Full Definition
The varus stress test is a clinical examination technique used to evaluate the integrity of lateral collateral ligaments, most commonly performed at the knee and ankle. The test involves applying a varus (inward angulation) force while assessing for abnormal joint opening or instability. At the knee, this test primarily evaluates the lateral collateral ligament and posterolateral corner structures. Increased joint space opening compared to the contralateral side indicates ligament injury or insufficiency.
Usage
Usage note: Distinguish clearly from valgus stress test; varus refers to inward angulation toward the midline.
