Document Summary
Cause of injury: result of severe blow or outward twist valgus force. Little fiber tearing or stretching: stable valgus test but there will be some pain. Little or no joint effusion: some joint stiffness and point tenderness on medial joint line aspect of the knee, relatively normal rom with a grade 1 mcl sprain. Joint effusion inside the knee will affect the ability to extend that leg more than the ability to flex the leg. When you have that joint effusion, you will see the capsular pattern and extension will be limited: pain along medial aspect of knee. Signs of injury grade 3: complete tear or supporting ligaments, complete loss of medial stability, meniscus disruption, minimum to moderate swelling. Loss of motion due to effusion and hamstring guarding: positive valgus stress test. There will be no pain because the ligament is torn. Care: rice or price (p stands for protection) for at least 24 hours.
