Joint Replacement Types
Hip Replacement Overview
The hip joint is made up of a ball-and-socket. The socket is made of bone and cartilage, and the ball is the top of the thighbone, also known as the femoral head.
Hip replacement surgery is an operation used to replace the damaged ball-and-socket with new and durable artificial synthetic parts that mimic the ball-and-socket.
