Knee replacement surgery, also known as knee joint arthroplasty (Arth-row-plas-tee) is a procedure that can relieve discomfort and improve function in knee joints that are severely damaged. The procedure involves removing damaged cartilage and bone from the shinbone, thighbone and kneecap, then replacing it with a synthetic joint (prosthesis) comprised from metal alloys, premium plastics and polymers. In determining whether a knee replacement is suitable for you, an orthopedic surgeon assesses your knee’s range of motion, stability, and strength. X-rays help determine the extent of the damage.
Your orthopedic doctor can choose various knee replacement prostheses and surgical techniques, considering your age, weight, activity level, knee size and shape, and overall health.
