Creating a tibial tunnel (socket) for passage and placement of new ACL
Creating a femoral tunnel (socket) in the position where the normal ACL inserts on the femur.
The central 1/3 of the patients own patellar tendon is harvested along with a small piece of bone from the patella and a small piece of bone from the tibia. The bone plugs are placed into the femoral and tibial tunnels (sockets) and held in position with a screw. The tendon in between the two bone pieces becomes the new ACL as seen here.

Arthroscopy is a surgical procedure in which an arthroscope is inserted into a joint. Arthroscopy is a term that comes from two Greek words, arthro-, meaning joint, and -skopein, meaning to examine.
The benefits of arthroscopy involve smaller incisions, faster healing, a more rapid recovery, and less scarring. Arthroscopic surgical procedures are often performed on an outpatient basis and the patient is able to return home on the same day.

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the centre of the knee running from the femur to the tibia. When this ligament tears unfortunately it doesn't heal and often leads to the feeling of instability in the knee.
ACL reconstruction is a commonly performed surgical procedure and with recent advances in arthroscopic surgery can now be performed with minimal incisions and low complication rates.
