The ACL is the ligament that connects the femur (thigh bone) and tibia (shin bone) inside the knee joint.Ligaments are tough, non-stretchable fibers that hold bones together. The ACL, along with the posterior cruciate ligament (PCL), medial collateral ligament (MCL), and menisci (cartilages), helps keep the knee stable and helps protect the knee from shifting, rotating, and hyperextending during running, jumping, or landing.ACL tears can occur from forceful contact to the front or outer part of the knee or from the knee twisting or hyperextending. An ACL tear is usually associated with sudden knee pain and a sense of the knee giving way.Cynthia LaBella, MD is here to discuss ACL injuries, their symptoms and treatments.
