Step-by-step explanation:
To diagnose a Grade III MCL (Medial Collateral Ligament) and ACL (Anterior Cruciate Ligament) tear, a physician will typically perform a physical exam. The physical exam may include various tests and maneuvers to assess the stability and integrity of the knee joint. Some of the common physical exam techniques for diagnosing a Grade III MCL + ACL tear may include:
- Lachman test: It evaluates the anterior stability of the knee joint and involves the physician applying an anterior force to the tibia while stabilizing the femur.
- Anterior Drawer test: It assesses the integrity of the ACL and involves the physician pulling the tibia forward while stabilizing the femur.
- Valgus Stress test: It evaluates the MCL and involves the physician applying a valgus force to the knee joint.
