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 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.

Cartilage Restoration

Articular Cartilage is the white tissue lining the end of bones where these bones connect to form joints. Cartilage acts as cushioning material and helps in smooth gliding of bones during movement. An injury to the joint may damage this cartilage which cannot repair on its own. Cartilage can be damaged with increasing age, normal wear and tear, or trauma. Damaged cartilage cannot cushion the joints during movement and the joints may rub over each other causing severe pain and inflammation.

Revision ACL reconstruction

The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is located in the middle of the knee and runs from the femur (thigh bone) to the tibia (shin bone).

Multi ligament 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).Two collateral ligaments are present on either side of the knee and control the sideway movements of the knee.

MPFL reconstruction (kneecap stabilization)

Patella (knee cap) is a protective bone attached to the quadriceps muscles of the thigh by quadriceps tendon.

Meniscus 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.

Meniscectomy

Meniscectomy is a surgical procedure indicated in individuals with torn meniscus where the conservative treatments are a failure to relieve the pain and other symptoms. Meniscectomy is recommended based on the ability of meniscus to heal, patient’s age, health status and activity level.

Autologous chondrocyte implantation

Autologous chondrocyte implantation (ACI) is a procedure to treat the articular cartilage defects of the knee. This procedure is effective for treating small areas of cartilage damage that causes pain and swelling and restricts the range of motion.

Microfracture

Microfracture is a surgical procedure used for cartilage restoration. Cartilage restoration is a surgical procedure where orthopedic surgeons stimulate the growth of new cartilage tissue and restore the normal function.

Subchondroplasty

Knee osteoarthritis (OA) is a common form of arthritis that causes joint pain and stiffness. It is a progressive disease in which the joint cartilage gradually wears away and may lead to disability.

Tibial Osteotomy

Knee Osteotomy is a surgical procedure in which the upper shinbone (tibia) or lower thighbone (femur) is cut and realigned.

Fractures

The knee cap or patella is the largest sesamoid bone in the body and one of the components of the knee joint, present at the front of the knee.
