The so-called sequelae of bone joint replacement are often referred to as complications and long-term complications. As a result of joint replacement, since it is an artificial joint, common complications include: first, dislocation; second, it can cause infection; third, it can cause rattling. For example, sometimes when ceramic hip replacement is performed, it can make a sharp rattling sound or a slight rattling sound; fourth, other problems. When there is pain after a longer period of time, it is also necessary to rule out loosening of the femoral head prosthesis or even whether there are other pathologies such as fractures around the prosthesis.
