The anterior cruciate ligament (ACL) is one of the four major ligaments in the knee that provides stability. The ACL originates from the back of the femur (thighbone) and inserts into the front of the tibia (shinbone). It prevents the tibia from sliding out in front of the femur and also limits rotation between the two bones. A tear or sprain of the ACL is a common knee injury that can occur during sports or other physical activities.
When an ACL injury occurs, it is often a result of a sudden change in direction or a deceleration injury. The knee joint is forced beyond its normal range of motion, causing the ACL to stretch or tear. In some cases, the ACL may rupture, or tear completely. Symptoms of an ACL injury include severe pain, swelling, and instability in the knee joint. An MRI is usually required to confirm the diagnosis.
There are two main options for treating an ACL injury: surgery or rehabilitation. Surgery is typically recommended for athletes or others who wish to return to high-level sports or activities. The goal of surgery is to reconstruction the torn ligament using a graft from another part of the body or from a donor. This surgery is usually followed by several months of rehabilitation to regain strength and range of motion in the knee joint.
For patients who do not wish to undergo surgery, rehabilitation may be an option. The goal of rehabilitation is to improve range of motion and strength in the knee joint without surgery. A physical therapist will develop a personalized rehabilitation program based on your individual needs and goals. Rehabilitation typically takes several months to complete.
If you have suffered an ACL injury, it is important to seek treatment as soon as possible. Surgery is typically recommended for athletes or others who wish to return to high-level sports or activities. However, rehabilitation may be an option for patients who do not wish to undergo surgery. A
