並列摘要
Purpose: The purpose of this study was to report the clinical results of a newly designed ceramic-on-ceramic total hip arthroplasty. Methods: Twenty-seven patients (31 hips) with a mean age of 45.3 years underwent primary total hip arthroplasty (THA) using contemporary ceramic-on-ceramic bearing prosthesis between July 2000 and March 2006. All patients were evaluated clinically using the Harris hip score system and radiographically, both before operation and at follow-up visits. Results: At an average follow-up of 52 months (range 2 to 8 years), the mean Harris hip score improved from 52 points (range, 26 to 81) pre-operatively to 95 points (range, 75 to 100) at the latest follow-up. All hips had radiographic evidence of bone in growth. Thirty of 31 hips (96.8%) achieved satisfactory results. There were no fractures or failures of ceramic bearings, no loosening of components or periprosthetic osteolysis, and no squeaking after operation. Second operations included revision of the acetabular component in 1 hip for recurrent posterior dislocations and open reduction and internal fixation of the femur in 2 hips for periprosthetic fractures. Conclusions: A high satisfactory result was reported using non-sandwich designed ceramic-on-ceramic THA of 27 patients followed up from 2 to 8 years. Fortunately, no ceramic bearing-related complications have been observed.
