Unicompartmental knee replacement works within a single compartment of the knee, usually the medial compartment, instead of all three compartments of the knee, like total knee replacement

Osteoarthritis of the knee is a prevalent form of arthritis that affects the cartilage, causing it to thin out over time, and as a result, the bones rub painfully against one another. Inadequate cartilage, bone degeneration and the presence of bone spurs may alter the anatomical shape of the joint.

Fortunately, partial knee replacement can be performed through a tiny incision over the knee rather than a large cut made during a total knee replacement.

Why is it done?

Indications for unicompartmental knee replacement include the following:

• Osteoarthritis of the knee affecting one compartment
• Age >60 years
• A stabilised body weight <82 kg
• Symptoms of inflammatory arthritis

How do you perform unicompartmental knee replacement surgery?

Unicompartmental knee replacement involves removing worn cartilage and bone and replacing them with artificial components. Dr Vardi creates an incision over the anterior region of the knee and creates a tunnel behind the patella in order to access the joint and remove the damaged cartilage. The procedure aims to preserve as much healthy tissue (ligaments and cartilage) as possible. Next, Dr Vardi prepares the damaged surfaces of the tibia and femur. Afterwards, he fits the prosthesis, which comprises the femoral and tibial components, in order to enhance the stability and flexibility of the knee. Using advanced computer-aided techniques, Dr Vardi can position the prosthesis accurately.

What is robotic unicompartmental knee replacement?

Robotic-assisted partial knee replacement is an advanced surgical approach to treat degenerative knee arthritis (osteoarthritis) that causes pain and swelling in the knee. The procedure entails utilising robotic-arm technology that allows Dr Vardi to precisely perform unicompartmental knee replacement through small incisions made over the knee.
