ABSTRACT
PURPOSE:
To present the survival of consecutive patients with a minimum of three years follow-up after undergoing a metal-on-metal hip resurfacing arthroplasty. MATERIALS ANDMETHODS:
Twenty hips from twenty patients (male 16, female 4) who underwent metal-on-metal resurfacing arthroplasty between October 2001 and April 2004 were followed up for at least 3 years. The mean patient age was 49 years (range 23~70), and the mean follow-up period was 56 months (range 36~84 months). A clinical evaluation was performed using the Harris hip score, and radiologic evaluation was performed regularly after surgery with plain radiographs.RESULTS:
The mean Harris hip score improved from 46 points (range 73~32) preoperatively to 94 points at final follow-up. There were no cases of radiolucency or osteolysis around the stem or acetabular cup, and there was no migration of the acetabular or femoral component. The average femoral stem-shaft angle was 135degrees(range 121degrees- 139degrees), and at the final follow-up study, there was no change of the femoral stem.CONCLUSION:
In the short-term, metal-on-metal resurfacing arthroplasty performed on the basis of bone quality and patient selection, showed excellent clinical and radiological results. Hip resurfacing is an attractive option for young patients fearing a potentially difficult future revision or for more active patients with hip disease.
