define arthroplasty
Arthroplasty Definition. Arthroplasty is surgery to relieve pain and restore range of motion by realigning or reconstructing a joint. Purpose. The goal of arthroplasty is to restore the function of a stiffened joint and relieve pain. Two types of arthroplastic surgery exist. Joint resection involves removing a portion of the bone from a stiffened joint, creating a gap between the bone and the socket, to improve the range of motion. Scar tissue eventually fills the gap.
