Knee Replacement

Overview

In knee replacement surgery, the damaged surfaces of the knee joint are removed and replaced with metal and plastic parts. It is most often done for severe arthritis.

Why it is done

• Severe knee pain that limits walking, climbing stairs or sleep
• Knee damage from osteoarthritis or rheumatoid arthritis
• When medicines, physiotherapy, injections and walking aids no longer help

Before the surgery

Your surgeon will review X-rays and your general health. Blood tests, an anaesthesia assessment and advice on preparing your home for recovery are usually part of the plan. Losing excess weight and doing exercises beforehand can help recovery.

During the surgery

The operation is performed under spinal or general anaesthesia and usually takes one to two hours.

After the surgery

Physiotherapy starts soon after surgery, often on the same or the next day. Most people stay in hospital for a few days and use a walker or crutches at first. Recovery continues over several months, and exercises are essential for a good result.

Risks

Possible risks include infection, blood clots in the legs, stiffness, persistent pain and, over many years, wear or loosening of the new joint.
