Anterior Cruciate Ligament Tear

By Jon Stiffler PTA/Sports Center Manager

Anterior Cruciate Ligament Tear or ACL Tear

This injury, ACL tears, is a tearing of the ACL ligament in the knee joint. The Anterior Cruciate Ligament is one of the bands of tissue that connects the femur to the tibia. ACL tears can be painful and it can cause the knee to become unstable.  The ACL is one of the major stabilizing ligaments in the knee. It prevents the tibia (Shin bone) moving abnormally on the femur (thigh bone). Furthermore, when this abnormal movement is known as instability.  The knee is unstable because of the laxity to the ligaments.

ACL Tears

ACL tears or sprain to the ACL Ligament is a serious injury.  The injury usually occurs with a mechanism of planting the foot and a cutting type motion.  However, there have been some injuries which occur just with stopping or starting to run.  With the ACL injury, an injury could also occur to the medial meniscus and medial collateral ligament tea.  This injury is know as an unhappy triad injury.

The surgical technique for this instability is an ACL reconstruction.  The ACL ligament is harvested from the patellar tendon or the hamstring tendon of the patient.  The patient may also choose a cadaver graft.

ACL Tear Rehab

Physical Therapy after an ACL Reconstruction is a major rehab for the knee.  Usually, it takes 5-6 months for the athlete to return to fully participation.  At JOI Rehab, our therapist worked with our JOI Surgeons, to develop ACL Rehab Protocols.  Our goal is a full return to your prior level of function.
