Physical Therapy Exercises for Recovery From a Clavicle Fracture
Ligaments are tough bands of fibrous tissue that connect two bones. The anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) are inside the knee joint. These ligaments connect the thigh bone (femur) and the large bone of the lower leg (tibia) at the knee joint. The ACL and PCL form an X inside the knee that stabilizes the knee against front-to-back or back-to-front forces. An ACL injury is a sprain or tear in which the ligament is stretched beyond its normal range.
