Total Knee Replacement (TKR), also known as total knee arthroplasty, is a surgical procedure to replace a damaged or worn-out knee joint with an artificial joint. This procedure is commonly performed for individuals with severe knee pain and limited mobility due to conditions such as osteoarthritis or rheumatoid arthritis. During a TKR, the surgeon removes the damaged joint surfaces and replaces them with metal and plastic components. Recovery typically involves physical therapy, pain management, and gradually returning to normal activities. TKR can provide significant pain relief and improve function and quality of life for those with severe knee joint damage.
