Joint Replacement

Much like hip replacement, knee replacement surgery is also a very successful operation. It is an operation performed for end stage arthritis of the knee joint, primarily to relieve pain, but can also be of help with correcting deformity and improving the movement of stiff knees.

The most common cause of knee arthritis is osteoarthritis, with other causes including rheumatoid arthritis and post-traumatic arthritis. Surgery is only considered once all non-surgical treatments fail to provide sufficient relief.

Joint replacement involves removal of all arthritic surfaces from the joint, with replacement by synthetic materials. The most common components are metal caps on the end of the femur (thigh bone) and tibia (shin bone). There will be a bearing surface between these and it is usually made of polyethylene (a form of plastic).

Joint replacements have an excellent track record, although as with any procedure, there are recognised risks. There are general risks that are common to all surgeries, and risks specific to joint replacement. Your surgeon will discuss these risks with you in detail, at the time of consultation.
