Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources.

Shoulder replacement removes damaged areas of bone and replaces them with parts made of metal and plastic (implants). This surgery is called shoulder arthroplasty (ARTH-row-plas-tee).The shoulder is a ball-and-socket joint. The round head (ball) of the upper arm bone fits into a shallow socket in the shoulder. Damage to the joint can cause pain, weakness and stiffness.
