One hundred eight uncemented total hip arthroplasties were performed in 91
patients who were 50 years of age or younger using the Taperloc femoral com
ponent. The average age of the patients at time of surgery was 37 years (ra
nge, 20-50 years). The mean followup was 10.2 years (range, 8-13 years), No
patient was lost to followup. Seven patients (eight hips) died before obta
ining the minimum time of 8 years for inclusion in this study. All seven di
ed with their femoral components in place, Of the remaining 100 total hip a
rthroplasties, no femoral component required revision for aseptic loosening
. One femoral component was revised to correct a leg length discrepancy, an
d one well-fixed femoral component was revised for sepsis, In the 98 total
hip arthroplasties that had not undergone femoral component revision, compl
ete radiographic and clinical followup was obtained. Radiographically, 96 (
98%) femoral components were determined to have fixation by bone ingrowth,
two (2%) femoral components showed stable fibrous ingrowth, and no femoral
component was unstable. Femoral cortical osteolysis occurred in seven (7%)
hips; major lysis was present in only one (1%), Clinically, 91 (93%) total
hip arthroplasties were rated good or excellent; six (6%) were rated fair,
and one (1%) was rated poor. Thirty-nine patients with 47 total hip arthrop
lasties (48%) were engaged in moderate to strenuous manual labor. These res
ults indicate that excellent fixation and minimal lysis can be achieved wit
h an uncemented femoral component in young and active patients at 10 years.
