The posterior cruciate ligament (PCL) is the ACL’s partner. It is located inside the knee and prevents the tibia (lower leg bone) from moving backwards on the femur (thigh bone). Injury to this ligament is fairly rare compared to ACL injuries. It can cause knee instability, especially with running, jumping, cutting.
A PCL tear/sprain most commonly occurs from a dashboard injury (when the dash gets pushed back into the knee in a car accident). This also can occur from a fall directly on knee. In sports injuries, a PCL tear/sprain is often found alongside injury to other knee structures.

When to Seek Help
If you are experiencing the above symptoms, please see your physical therapist immediately. Your physical therapist will provide a comprehensive evaluation and determine if you need medical imaging or further assessment by an orthopedic surgeon, as well as provide immediate treatment to get you feeling and moving better – you won’t find this in an orthopedic quick care or PCP’s office!
