Surgery for Anterior Cruciate Ligament (ACL) Injury

The ACL (anterior cruciate ligament) is a band of tough, fibrous tissue that helps stabilize the knee. Injury to this ligament often happens when the knee is forced beyond its normal range of motion. This can stretch or tear the ligament, much like the fibers of a rope coming apart. Both surgical and nonsurgical treatment has been used to recover from an ACL tear. Several types of surgery are available based on you and your healthcare provider's preferences as well as other factors. Some surgeons will operate soon after an ACL tear, others prefer several weeks of physical therapy first. There are also different anesthesia choices available.

Preparing for surgery

Do's and don'ts:

  • Stop taking aspirin and other medicines 7 or more days before surgery as advised by your healthcare provider.

  • Arrange to get crutches to use during recovery.

  • Don’t eat or drink for 10 hours before surgery.

  • Arrange for an adult to drive you home after surgery.

The most common type of surgery for an ACL injury is reconstruction. There are several types of surgeries used:

  • Patellar tendon graft, which uses a piece of your own patellar tendon between the knee cap and tibia

  • Quadriceps tendon graft, which uses a piece of your own quadriceps tendon between the quadriceps muscle and the knee cap

  • Hamstring tendon graft, which uses a piece of your own hamstring tendon between the hamstring muscle and the tibia

  • A cadaver (allograft) tendon graft, which uses any one of several tendons from a cadaver

To rebuild your ACL, your healthcare provider may do open surgery or arthroscopy. During arthroscopy, a long, thin tube with a tiny camera is inserted into the knee joint so your healthcare provider can see inside the joint. Tools inserted through small incisions are used to repair the joint.

After surgery

Here is what to expect:

  • You’ll spend a few hours in a recovery area. You’ll have ice on your knee to prevent swelling, and your leg may be in a brace.

  • You may receive a continuous cooling machine to relieve swelling and pain.

  • You may receive medicines to reduce pain and swelling. Take these as prescribed by your healthcare provider.

  • Depending on the procedure, physical therapy may begin shortly after surgery. This may include light exercises. In some cases, you may use a CPM (continuous passive motion) machine for a time. This machine flexes and extends the knee, keeping it from getting stiff.

  • You can usually go home the same day as surgery. Have an adult family member or friend give you a rid
