Total hip arthroplasty with an uncemented femoral component - Excellent results at ten-year follow-up

We followed 138 patients (145 hips) who had had uncemented total hip arthroplasty using the Taperloc femoral component for a mean of tell years (8 to 12.5). No patient was lost to follow-up; 31 (31 hips) died before the minimum time of eight years for inclusion in the study, and 30 of these still had their femoral component in place, One well-fixed prosthesis had been exchanged at the time of acetabular revision, Of the remaining 114 hips, one femoral component required revision for aseptic loosening and one for sepsis. Three other well-fixed femoral components mere removed during acetabular revision. Complete clinical and radiological follow-up was obtained in the 109 hips which had not had revision, Clinically, 94 (87%) mere rated good or excellent, eight (7%) fair and seven (6%) poor, The average Harris hip score increased from 48 before operation to 88 at the time of the last follow-up, Radiologically, 103 hips (94%) had fixation by bone ingrowth, three (3%) showed stable fibrous ingrowth and three (3%) were unstable, Osteolysis of the femoral cortex was seen in seven hips (6%), with major lysis in only one. At a mean follow-up of ten years, the results of the Taperloc femoral component are comparable with those of modern techniques of cementing in primary total hip arthroplasty.
