Revision of the artificial total hip joint refers to the surgery after the artificial hip joint replacement, due to different reasons, the artificial joint cannot meet the physiological needs of the human body, and further removal or replacement of the prosthesis is needed to achieve the treatment purpose. In some cases, revision surgery is required again or several times. Due to the soft tissue scarring and bone loss caused by the surgery, revision surgery is much more difficult and the stability and durability of the postoperative prosthesis is relatively poor, and the results are not as satisfying as the initial replacement, but there is no alternative. Revision surgery takes a long time and involves a lot of blood loss, and postoperative complications such as infection, dislocation, thrombosis, nerve damage, femoral fracture, etc. are significantly increased, and the durability of the prosthesis is somewhat reduced. Therefore, revision surgery should be performed by a surgeon with extensive experience. Common reasons for revision include: loosening of the prosthesis; fracture of the prosthesis; repeated dislocation or joint dislocation that cannot be repositioned; post-arthroplasty infection; periprosthetic fracture, etc. During revision surgery, it is necessary to preserve bone tissue to the greatest extent possible, assess the degree of acetabular and femoral bone defects, develop a reasonable reconstruction method, prepare various revision surgery instruments to facilitate the removal of the prosthesis and residual bone cement, and prepare various types of revision prostheses: cement type, biological type, modular prosthesis, reinforcement cup, various fresh bone graft materials, etc.
