VALGUS STRESS TEST FOR MEDIAL COLLATERAL LIGAMENT (MCL) INJURIES The Valgus or Abduction Stress Test is designed to stress the medial collateral ligament. In the 0° position, the test stresses the Posteriomedial complex (PMC) which is composed of the MCL, posterieure horn of the mediale meniscus, Posterior oblique ligament, semimembranosus expansions, meniscotibial (coronary) ligaments and the oblique popliteal ligament. In 20° flexion, the MCL is rather tested in isolation as less stress will b

MOVING VALGUS STRESS TEST FOR MEDIAL COLLATERAL LIGAMENT INSUFFICIENCY OF THE ELBOW If your patient is presenting after a trauma of the elbow and with medial elbow pain, one of the first things you want to test (after excluding a fracture) is the integrity of the ligaments. The moving valgus stress test is used to assess the medial collateral ligament at the elbow. According to a small study of O'Driscoll et al. (2017) the Moving Valgus Stress test has a sensitivity of 100% and a specificity of
