Sequelae of total hip replacement include pain, infection, loosening, and limitation of joint movement. However, the above sequelae are currently not very likely to occur after strict pre-operative evaluation and strict intra-operative operation, and not all patients will experience them. 1. Pain: If the limbs on both sides are not equal after total hip replacement, it will cause pain around the hip joint. 2. Infection: After surgery, if the wound is not well cared for or if there is an infected lesion in the body itself, it can cause the hip joint to become infected and septic, and the pain will be obvious. 3. Loosening: After the surgery, there is no good maintenance, strenuous exercise or the service life of the prosthesis causes loosening or displacement of the prosthesis. 4. Restriction of joint movement: If there is no rehabilitation exercise after surgery, it will cause restriction of hip joint movement. After total hip replacement surgery, you need to do rehabilitation exercise under the doctor’s guidance.
