ACL Surgery is a procedure in which damaged anterior cruciate ligament in the centre of knee is replaced with a new ligament. Anterior Cruciate Ligament is mainly responsible to join the femur to the tibia and to keep the tibia (shin bone) in right place. A torn or damaged ACL cannot be repaired successfully so it must be replaced with a new tissue graft.



Computer-aided navigation systems offers great precision & accuracy in tunnel placement minimizing the need of revision surgery. In Computer Navigated Minimal invasive technique, a small incision is made on knee joint and then knee arthroscope (a narrow tube, which has a camera and light source in it) is inserted into knee joint to view the damage on a monitor. After analyzing the damaged joint, other incision/s is made to insert surgical instrument through these incisions and then the damaged ligament is removed with the help of instruments and then new tissue is put in the place of old tissue. Then new ligaments are then attached to the surrounding bones to keep them in right place and then incisions are sewn back.


The new tissue used can be from the patient’s own body or from a deceased donor. Accordingly they are called as-

  • Autograft – If the grafted tissue is taken from the patient’s own body, it is called autograft. Generally tissue is taken from knee cap tendon or from the hamstring tendon.
  • Allograft – When tissue is taken from a deceased donor, it is called as allograft.
