Basic Biomechanics of Ligaments, Tendons, and Joints - Mechanisms of Joint Injury

Module 1 of MSK Biomechanics begins by covering joint subluxation vs dislocation and common joint valgus vs varus stress injuries. Dr. Wilde discusses the types of joint movements including angulation, translation, rotation, external force, and internal force as well how intracapsular abnormalities can provide clues to the causes of joint injury. Knee valgus injuries in sports are demonstrated including skiing, hockey, and football injuries with demonstration of the valgus stress test to assess the integrity of the MCL. Knee posterior translation injuries, FOOSH, and dislocation injuries of the elbow are presented. The last section includes biomechanics of the foot with a demonstration of the anterior drawer test to assess the integrity of the anterior talofibular ligament and the talar tilt test to assess the integrity of the calcaneofibular ligament. In conclusion, key patient history questions are explored.
