Osteoarthritis (OA) is a condition that causes pain and stiffness in the joints, often due to injuries like torn ligaments. Even after surgery, these injuries can lead to long-term joint problems. Current treatments don\'t fully prevent OA from developing. This study is testing a new 12-week exercise program designed to improve how the knee moves, using a special sensor-based system. The goal is to reduce joint inflammation and prevent the development of OA in patients who have had knee surgery.
