Anterior cruciate ligament (ACL) revision
A surgical procedure to correct a failed ACL repair operation.
About ACL revision surgery
Anterior cruciate ligament (ACL) revision surgery is a procedure to correct a failed ACL reconstruction. The ACL is a thick band of tissue that joins the thigh bone to the shin bone in your knee. It can be torn as a result of a sudden twisting or wrenching movement. If you've had ACL reconstruction surgery in the past, it's possible that the graft (a tendon taken from another part of your body) might have failed. This could be because:
- the graft was attached at the wrong point in the bone
- other knee instabilities were not addressed during the original procedure
- your body did not accept the graft properly
- you returned to activity before your body had accepted the graft properly
How is ACL revision carried out?
ACL revision is carried out through keyhole surgery (arthroscopically), usually under general anaesthetic. You'll be asleep during the operation. Your surgeon makes a number of small cuts and inserts a telescopic video camera and surgical instruments. Depending on the cause of graft failure, your surgeon might need to graft more bone into the original area where the tendon was attached.
- If the graft tendon has torn – your surgeon will take more tendon from your thigh or knee or may use a donor ligament, and insert the ends into your thigh bone and shin bone.
- If the cartilage has torn – your surgeon will correct these issues by shaving or repairing the cartilage .
Recovering from ACL revision
You will usually go home on the same day as the surgery, or when you have recovered from the anaesthetic.
Recovery from revision reconstruction is usually takes longer than for the original ACL reconstruction.
Initially, you will need to rest your leg and keep it elevated as much as you can.
You'll need to use crutches for up to four to six weeks and wear a knee brace for a similar amount of time.
You can expect to return to work about six weeks after the operation if your job isn't too physically demanding. Those with more active jobs will need a longer recovery time.
You should be able to start doing single leg squats and gentle jogging after four months. It usually takes nine months to make a full recovery and return to sports.
