What three structures are typically damaged from a blow to the lateral aspect of the knee joint?

A blow to the lateral aspect of the knee joint typically damages the medial collateral ligament (MCL), the medial meniscus, and the anterior cruciate ligament (ACL). The impact can cause the knee to buckle inward, leading to strain or tears in these structures. This type of injury is often referred to as a valgus stress injury. Immediate assessment and treatment are crucial to prevent long-term instability or complications.
