Knee Replacement

Knee Replacement, also known as Total Knee Arthroplasty (TKA) or Total Knee Replacement (TKR), is a surgical procedure where the damaged cartilage and the bone from the surface of the knee joint are replaced with artificial components. This procedure is performed on people of all ages, with the exception of children, whose bones are still growing. Normally the knee functions like a hinge between the femur – the thigh bone and the tibia and fibula – the lower leg bones. The articulating surfaces of these bones wear out over time because of arthritis or other such conditions that cause pain and swelling. Thus, the vital goal of knee replacement is to relieve pain, improve quality of life, and maintain or improve knee function.

Risks and Complications
Most knee joint operations are problem-free but about 1 person in every 20 may have complications. Most of these complications are minor and can be successfully treated.
The risk of complications developing will depend on a number of factors including your age and general health. In general, a younger patient with no other medical problems will be at a lower risk of complications.
It’s important to remember that any drugs used throughout your stay in hospital, for example anaesthetic or painkillers, may also have side-effects. Your surgeon or anaesthetist will be able to discuss these with you.
