What is knee replacement surgery?

Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure in which a damaged or diseased knee joint is replaced with an artificial joint, called a prosthesis. This procedure is commonly performed to relieve pain and restore function in individuals with severe knee arthritis or other conditions that affect the knee joint. During the surgery, the damaged portions of the knee joint, including the cartilage and bone, are removed and replaced with metal and plastic components that mimic the natural movement of a healthy knee. Knee replacement surgery can significantly improve mobility, reduce pain, and enhance the overall quality of life for individuals with debilitating knee conditions.
