Abstract:

BACKGROUND: With the prevalence of total hip arthroplasty, the demand for revision has been increased due to the prosthesis life and various complications.

OBJECTIVE: To retrospectively analyze the reasons and clinical effectiveness of revision, clinical application of revision prosthesis, and related revision techniques.
METHODS: Clinical data of 85 patients undergoing total hip revision were analyzed retrospectively. Among which, there were 23 cases of biological T.O.P acetabular cup (allograft bone graft) plus polyethylene liner, 51 cases of titanium mesh cup plus bone cement fixation, and 11 cases of common acetabular cup; common hip stem in 63 cases (including 47 cases of bone cement fixation); lengthened hip stem in 34 cases (16 cases of modular prosthesis and 18 cases of bone cement fixation). Subsequently, the hip function was assessed by Harris hip scores.
RESULTS AND CONCLUSION: All cases were followed up, and the mean follow-up was 30.2 months. (1) The average Harris hip scores changed from preoperative 30.07 to postoperative 90.32. The wound healed well, no dislocation or infection, and the hip function was improved significantly. (2) To conclude, aseptic loosening of the prosthesis is the main cause of reversion occurred, followed by prosthesis dislocation. Acetabular wall bone defect and decrease in bone mass are the main problems in revision. Adequate preoperative preparation for possible and unexpected events, and reasonable selection of prosthesis according to the bone defects will be helpful. Noticeably, early arthroplasty reversion will obtain good clinical efficacy.
