What is the ACL?
The anterior cruciate ligament is one of the major ligaments in your knee. Ligaments are the bands of fibrous tissue that connect bones, cartilage or joints. Says Dr. Feder, “The ACL is one of two ligaments that cross in the middle of the knee and help stabilize the knee joint. It connects the thigh to the lower leg.” It is most commonly injured during sudden stops or changes in direction. The ligament is crucial for starting, stopping, changing direction and landing.

Torn-ACL
How do you know you injured your ACL?
When the injury occurs, people often hear a “pop” and feel their knee give out. The severity of an injury to the ACL varies from small to complete tears in the ligament to a separation of the ligament from the bone. The most common injury is a complete tear in the middle. Most often, it’s an all or nothing injury. While ligaments in other parts of the body can heal, this one can’t because fluid in the knee impedes healing. There is an estimated 100,000 ACL tears a year in the United States. Female athletes are about five times more likely to get them than men.
What happens in ACL surgery?
For many people, a surgeon likely would replace the torn ligament with a piece of the patient’s patella tendon, quadriceps tendon, or hamstring tendon tissue from a cadaver.
Elite athletes are on a different protocol. In their case, surgeons utilize the patella tendon and remove a two-inch-long piece of a tendon that runs under the kneecap along with bone on either end and screw it into place. The tendon is a little wider than an inch. The surgeon makes a strip for the new ligament out of the middle third. Over the next few months, the tendon regenerates itself and the cellular structure of the reconstructed strip changes from tendon to ligament.
Why does it take so long to recover?
It takes time to rebuild strength in leg muscles and for the tendon and new ligament to heal and generate a new blood supply. To restore strength and to restore muscle coordination as well as what’s called proprioception which is kind of knowing where your joint is in space.
