The hip joint is made up of the ball and socket, where the socket is made of bone and cartilage, and the balls are the top of the thigh bone called the femoral head. Sometimes, any injury to the socket of the hip or even the thigh bond leads to pain, or difficulty with regular tasks, and the pain subsides. To overcome such situations, hip replacement surgery is the operation that replaces the damaged ball and socket with a new and durable artificial synthetic part which mimics the ball and socket.
