Downtown Physical Therapy treats many conditions related to the knee, this includes post-surgical Anterior Cruciate Ligament (ACL) repairs. Here is what to expect after ACL surgery.

WHAT IS AN ANTERIOR CRUCIATE LIGAMENT (ACL) INJURY?

The ACL is a ligament that runs diagonally in the middle of the knee. It prevents the tibia from sliding out in front of the femur, as well as provides rotational stability to the knee. One of the most common knee injuries is an anterior cruciate ligament sprain or tear. Athletes who participate in high demand sports are more likely to injure their anterior cruciate ligaments. An injury to an ACL, may require surgery to regain full function of your knee.

WHEN IS AN ACL SURGERY PERFORMED?

The surgical procedure is performed by an Orthopedic surgeon after testing has been performed to determine the severity of the injury. This testing can include a physical test, x-rays, and MRI’s.

Most ACL tears cannot be sutured back together. To surgically repair the ACL and restore knee stability, the ligament must be reconstructed. Your orthopedic surgeon will replace your torn ligament with a tissue graft. This graft acts as a scaffolding for a new ligament to grow on.

Grafts can be obtained from several sources. Often they are taken from the patellar tendon, which runs between the kneecap and the shinbone. Hamstring tendons at the back of the thigh are a common source of grafts. Sometimes a quadriceps tendon, which runs from the kneecap into the thigh, is used. Finally, cadaver graft (allograft) can be used.

There are advantages and disadvantages to all graft sources. You should discuss graft choices with your own orthopedic surgeon to help determine which is best for you.

HOW LONG IS THE RECOVERY PROCESS AFTER ACL SURGERY?

Most procedures are performed in outpatient facilities, meaning the patient can return home same day.  While recovery time is on a case per case basis, one can expect up to 6 months before returning to full activity.
