Arthroscopy of the Knee Joint
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.

Anterior Cruciate Ligament ACL Reconstruction
The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the center 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 incision and low complication rates.

Multiligament Knee Reconstruction
The knee is the most complex joint in the body and is formed by the articulation between the thigh bone (femur) and the shinbone (tibia). A knee cap is present over the front of the joint to provide extra protection. These bones are held together by four strong rope-like structures called ligaments. Two collateral ligaments are present on either side of the knee and control the sideway movements of the knee. The other two ligaments are the anterior and posterior cruciate ligaments, ACL and PCL respectively, which are present in the centre of the knee joint and cross each other to form an “X”. The cruciate ligaments control the back and forth movement of the knee.

Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of the bone separates from the end of the bone because of inadequate blood supply. The separated fragments are sometimes called “joint mice”. These fragments may be localized, or may detach and fall into the joint space causing pain and joint instability.

Meniscus Tear and Repair
Meniscus tear is the commonest knee injury in athletes, especially those involved in contact sports. A suddenly bend or twist in your knee cause the meniscus to tear. This is a traumatic meniscus tear. Elderly people are more prone to degenerative meniscal tears as the cartilage wears out and weakens with age. The two wedge-shape cartilage pieces present between the thighbone and the shinbone are called meniscus. They stabilize the knee joint and act as “shock absorbers”.
