A Total Knee Replacement, also known as Knee Arthroplasty, is a procedure that is undertaken to relieve pain and restore function of knee joints which are severely worn out due to arthritis.
What is a Total Knee Replacement?
During the procedure, damaged cartilage and bone are cut away, and are replaced with a Prosthesis (artificial joint). The Prosthesis is made from metal and high-grade plastic.
There is a broad range of knee replacement prostheses which can be chosen. The type which your doctor chooses will be dependent on several factors, including the size and shape of your knee, your age, your overall health, and your activity level.
The decision to undergo a Total Knee Replacement is a joint one between you, your family, GP and the Orthopaedic Surgeon. Those who benefit from a Knee replacement have one of the following symptoms:
- Severe pain or stiffness in the Knee that limits day to day activities like walking, climbing stairs, and getting into and out of vehicles.
- Knee deformity: bow leg or knock knee
- Severe Knee pain at rest or disturbing sleep
- Failure to improve with other treatments like pain killers/anti-inflammatory tablets, cortisone injections or physiotherapy
It should be noted that there are no restrictions for a Total Knee Replacement in terms of weight or age. In general, patients who undergo this procedure are aged between 50 and 80 years old, although the procedure can be performed on people of all ages.
