A patient with pain after right total hip arthroplasty (THA) in the Affiliated Hospital of Nanjing University of Traditional Chinese Medicine was recorded. The patient conducted the posterolateral approach hip revision by comprehensive diagnosis after admission. The AIHIP system was used for preoperative design. During the operation, it was found that the polyethylene liner was worn and broken, but the bone of the acetabular cup was well inserted and extremely firm. Therefore, the internal surface of the acetabular cup was polished, the polyethylene liner was implanted, and the revision was performed by using bone cement fixation, instead of all replacement of the femoral head, lining and acetabular side prosthesis. The operation was successful, the patient recovered well after the operation, and was cured and discharged. The loss of conventional polyethylene material lining is about 20 years, and the lining of this patient was worn through and broken in 8 years after surgery without further loosening of the prosthesis, which was relatively special. In this study, the causes of rupture and treatment revision methods were discussed, surgery, treatment methods and precautions were exchanged, and relevant literature was reviewed.
