ACL Reconstruction

Arthroscopic ACL Reconstruction


Anterior Cruciate Ligament (ACL) Reconstruction is performed arthroscopically, usually using a single hamstring tendon. Other grafts are Patella tendon, Quadriceps tendon or Allograft (Donor Tissue). The procedure takes approximately 1 to 1 and 1/2 hours depending on other pathology within the knee. ACL injury is often accompanied by meniscal or articular cartilage injuries.

There are important differences between ACL Reconstruction in adults and children because of the presence of Growth Plates. ACL injury in children is preferably treated early, due to the increased risk of meniscal tears and further injuries in the untreated group. ACL Repair is the preferred treatment for ACL tears of the femoral attachment. This must be managed early so it is vital that the patient is seen as soon as possible after the injury.

The hospital stay is one night. Crutches and a brace are used for 2-3 weeks. If there has been a meniscal repair as well as an ACL reconstruction, crutches and a brace will be needed for 4 weeks.

Post-operatively, icing begins immediately. You will be able to get out of bed when comfortable and usually discharged the following morning. You will be seen by a Physiotherapist before discharge, and advised about your rehabilitation program.

An appointment is made for 1 week post-operatively, for removal of the dressings and wound review. Rehabilitation is again discussed and instructions given. You have the opportunity to ask questions about the surgery and post-operative course. It is important that you have a physiotherapist to run your rehabilitation program. Generally the first 4 months are spent regaining range of motion and strength. You are usually off crutches by 3 weeks. Running usually starts around 4 months and sport at 8-10 months in adults and 12 months in children.
