This study was designed to evaluate the minimum 10 year results of a cementless
straight tapered stem with rectangular cross-section for revision. Between October
1991 and the end of 1998, 129 patients (138 hips) underwent revision surgery. 51
patients (54 hips) died during the follow-up time. Their implants had been followed
radiographically. Four of them had been revised again, 3 for aseptic loosening and
one because of a periprosthetic fracture. 13 patients refused to come to follow-up
because of poor cooperation or advenced age. None of these patients were revised.
Five patients were lost to follow-up. Seven patients had to be revised 1.4 to 11 years
post surgery, 6 for low-grade infection and one for periprosthetic fracture. This left a
total of 59 hips (54 patients) for analysis at a follow-up time of 10.0 to 16.9 (mean
12.3) years. For radiographic FU, monitor-guided ap and axial radiographs were
recorded. These were analyzed according to Gruen. From a total of 59 hips reviewed
more than 10 yeas postop. 56 were classified as stable. Two patients were at risk,
both presented with osteolytic lesions, one of them with metal-on-polyethylene and
one with metal-on-metal articulation. One patient was revised because of aseptic
loosening after 14 years. Again a cementless revision stem was inserted. The results
of the study are showing that the SLR-revision stem is a valuable implant for
cementless fixation in revision surgery.
