Why may I need ACL surgery?

You may need anterior cruciate ligament (ACL) surgery if you have an ACL tear because ACL tears do not heal. If you want to stay active, if you want to continue to do running and jumping and cutting activities, the ACL tear needs to be repaired and reconstructed surgically.

Whether or not someone may need ACL surgery depends on the patient’s function and the stability of their knee.

Although the anterior cruciate ligament (ACL) cannot heal, one in three people can regain enough strength in the knee to return to nondemanding activities without surgery. But this isn't easy. It may require a year of rehabilitation before muscles are strong enough to compensate for the loss of ACL-provided stability. Even so, your knee may sometimes pop out of joint. Your doctor may suggest an ACL brace to use during occasional strenuous activity. If you wish to return to activities involving jumping and pivoting, you will probably need surgery.

To determine whether you should have surgery, you and your doctor will need to consider your age, your activities, how unstable your knee is, whether your ACL is partially or completely torn, and other injuries. Patients who undergo ACL reconstruction surgery have long-term success rates of 82% to 95%. However, the reconstructed ACL fails or becomes unstable in about 8% of cases.
