The Anterior Cruciate Ligament (ACL) is a strong ligament inside the knee joint connecting the femur (thigh bone) and tibia (shin bone). Its main role is to control the amount of rotation and glide between the two bones during activity. This ligament can be partially torn or completely torn (ruptured) in an accident leading to feelings of instability and pain.

Reconstruction of the ACL involves using either two of the hamstring tendons or part of the knee cap tendon (patella tendon) to create a new ligament. Surgery is carried out as a day case and patients are discharged with a bandage around the knee and go home walking with crutches.

Rehabilitation following this operation is just as important as the surgery itself. Outpatient physiotherapy will be arranged and should continue for up to 6 months. There is a gradual return to full activities with running from 3 months and contact sports such as football permitted after 12 months.
