Total Knee Replacement
Total knee replacement surgery replaces a damaged knee joint with artificial components made of metal and plastic. This procedure relieves pain and restores function in knees severely damaged by arthritis or injury. Modern knee replacements are highly successful, lasting 15-20 years or more for most patients. Surgery is recommended when conservative treatments no longer control pain and disability significantly impacts quality of life.
