Knee replacement (TKR), also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. The knee is one of the most complex joints in the body. The knees support the body's entire weight and are vulnerable to injury and arthritis.
It is most commonly performed for osteoarthritis. Other major causes of debilitating pain include meniscus tears, cartilage defects, and ligament tears. Debilitating pain from osteoarthritis is much more common in the elderly.
Knee replacement surgery can be performed as a partial or a total knee replacement. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued function and motion of the knee.
Treatment for knee pain and joint damage caused by injury or arthritis may involve weight loss, anti-inflammatories, pain killers and activity modification. Physiotherapy, use of a cane or walker, steroid injections, and visco-supplementation or a combination of these therapies may be used to delay joint replacement.
Severe damage to the knee that does not respond to these treatments may require total knee replacement. Should a patient require a TKR, Dr McAllister will discuss all the risks and benefits. The practice sisters, Colleen or Carol will also spend an hour with the patient prior to the operation to go through any issues, worries and concerns, as well as to conduct a preoperative medical. Each patient is given a comprehensive booklet which covers everything you need to know about a TKR and what to expect after the operation.
Dr McAllister uses a technique developed and refined in Scotland which allows minimal pain and very rapid rehabilitation.
