What is Anterior Cruciate Ligament (ACL) Surgery?

This is surgery to reconstruct the anterior cruciate ligament (ACL) in the knee after it is torn. Often, a graft made of tendon is used to reconstruct the torn ligament.

ACL surgery is an elective procedure. This means that surgery is not always necessary; it may depend on your lifestyle and age. The decision to have surgery should be made after talking to your doctor about:

  • Your athletic and occupational needs
  • The level of joint stability in your knee
  • Any other damage to the knee

Surgery may be recommended if you have:

  • A complete tear of the ACL
  • A high degree of joint instability
  • Injury to the knee that affects more than one ligament
  • A need to return to sports or other activities that require pivoting, turning, or sharp movements
  • No improvement with rehabilitative therapy

Possible Complications

Complications are rare, but no procedure is completely free of risk. If you are planning to have ACL surgery, your doctor will review a list of possible complications, which may include:

  • Instability of the knee (rupture or stretching of the new ligament)
  • Reconstructed ACL does not work properly
  • Kneecap pain after surgery
  • Stiffness in the knee
  • Loss of full range of motion
  • Numbness
  • Infection
  • Bleeding
  • Blood clot formation
  • Reaction to anesthesia

Discuss these risks with your doctor before the surgery.

Call Your Doctor

After you leave the hospital, call your doctor if any of the following occurs:

  • Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
