Anterior Cruciate Ligament Tear

Kaylee Brooks

Where is the ACL? What does it do?

The anterior cruciate ligament is found inside of the knee. The ACL and the PCL, posterior cruciate ligament is similar to the ACL but is larger and stronger, cross to form an “X” with the anterior cruciate ligament in front. These ligaments control the back and forth motion of your knee. The ACL runs diagonally in the middle of the knee. It keeps the tibia from sliding out in front of the femur and provides rotational stability to the knee

Symptoms of a ACL Tear

The symptoms of an injury to the anterior cruciate ligament injury are “popping” sound at the time of injury, swelling of the knee within six hours, and pain, especially when trying to put weight on the injured knee). Excessive laxity with or without the athlete experiencing pain can indicate a tear or sprain to the ACL.

Nonsurgical treatment for the ACL is progressive physical therapy and rehabilitation. But most ACL tears require surgery. The four different types of surgeries are the patellar tendon autograft, hamstring tendon autograft, quadriceps autograft and allograft (taken from a cadaver) patellar tendon, Achilles tendon, semitendinosus, gracilis, or posterior tibialis tendon.

Rehab after Surgery

Rehabilitation after ACL surgery can take up to a year for a full recovery. In the first two to ten weeks, you will be going to physical therapy will take place three times a week. In weeks ten to twelve it will reduce to twice a week and after week twelve it will be once a week or as needed.
