Knee replacement surgery, also known as knee arthroplasty, is one of the most successful procedures in orthopaedic medicine. It involves replacing the damaged surfaces of the knee joint with artificial implants made of metal and plastic.
Who Needs Knee Replacement?
Knee replacement is typically recommended for patients who have: - Severe knee pain that limits daily activities like walking, climbing stairs, or getting up from a chair - Moderate to severe knee pain while resting - Chronic knee inflammation and swelling that doesn't improve with rest or medications - Knee deformity — a noticeable bowing in or out of the knee - Failure to respond to other treatments like medications, injections, or physical therapy
The Procedure
During knee replacement surgery, the surgeon removes damaged cartilage and bone from the knee joint and replaces it with artificial components. The surgery typically takes 1-2 hours and is performed under regional or general anaesthesia.
