5.What Happens During Surgery?
Knee replacement usually takes 1 to 2 hours. The surgeon removes damaged cartilage and bone from the knee. Then the doctor attaches metal implants to the ends of the thigh and calf bones. A plastic spacer goes between the metal pieces and helps the new joint move smoothly.
6.Your Hospital Stay
Most people stay in the hospital for one to two days or longer after knee replacement surgery. You will take some pain medicine. You should try to move your leg soon afterward. Moving around increases blood flow to the leg muscles and can help reduce swelling.
