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.

Total Knee Replacement (TKR)

A total knee replacement (TKR) or total knee arthroplasty is a surgery that resurfaces an arthritic knee joint with an artificial metal or plastic replacement parts called the ‘prostheses'.

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.

Uni Condylar Knee Replacement

This simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement. The knee joint is made up of 3 compartments, the patellofemoral and medial and lateral compartments between the femur and tibia (i.e. the long bones of the leg). Often only one of these compartments wears out, usually the medial one. If you have symptoms and X-ray findings suggestive of this then you may be suitable for this procedure.

Cruciate Ligaments

The anterior cruciate ligament (ACL) is a major ligament within the knee that connects the femur and the tibia and is very important for the stability and function of the knee. It is a fascinating mechanical stabiliser. Composed of collagen, it has 2 main functional bundles. An intact ACL opposes excessive translation between the femur and tibia in the anterior to posterior (front to back) direction and it also has a critical role in stabilising rotational movement.

Meniscal Injuries

Knee arthroscopy is a common procedure that orthopaedic surgeons use to examine and treat the inside of the knee. An arthroscope, a thin fibre-optic telescope about the width of a pencil, is passed into the joint through a small incision at the outer side of the knee. This is done under an anaesthetic.

Meniscal Injuries    

Articular Cartilage Injuries

Damage to the surface cartilage increases the friction in the kee joint and decreases its shock-absorption ability. If large pieces of cartilage are floating inside the knee joint, particularly if they are attached to a bone fragment, the joint may lock. These “loose bodies” cause further damage to the joint surfaces and osteoarthritis, which will worsen with time. The aim of surgery is to smoothen rough edges of the articular cartilage and remove loose debris.

Partial Knee Replacement

Uni-compartmental knee replacement is a type of resurfing option for the arthritic knee where only one of the articular compartments is affected by arthritis. Typically, this is the medial compartment of the knee.

Revision Knee Replacement

This means that part or all of your previous knee replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.
