21-year results of the uncemented fully textured lord hip prosthesis.
We report the updated results for a previously evaluated patient cohort who had uncemented total hip arthroplasties using the Lord femoral component. The original cohort consisted of 114 total hip arthroplasties (110 patients) performed from 1979 to 1984. The patients were followed up for an average of 21 years postoperatively. We describe the radiographic findings of 57 hips. At the last followup 11 (9.6%) of the 114 femoral components were revised or removed. Excluding infection there was an 83% 21-year survival according to Kaplan-Meier analysis. No significant radiographic changes occurred since the last publication. The prostheses are very well-fixed with no signs of loosening. Our current findings show the durability of the uncemented Lord femoral component indicating this prosthesis provides good long-term results.
