| Popis: | Purpose. To review the outcome of revision hip arthroplasty using extensively coated femoral components. Methods. We reviewed the results of revision involving 24 extensively porous-coated cementless femoral components in 23 patients, whose mean age was 52.4 years (range, 28.0–79.0 years). Most revisions were performed for aseptic loosening of the previously cemented femoral component. All patients were followed up for a minimum period of 24.0 months (mean, 61.1 months). Results. Of the 24 femoral stems, 20 showed bone ingrowth, 3 showed stable fibrous ingrowth, and one was unstable because of deep infection. Intra-operative anterior femoral diaphyseal perforation occurred in 2 hips during the insertion of straight femoral components of 200 mm. Postoperative radiographs displayed marked cortical erosion in 3 other hips and cortical perforation in one. Conclusion. The results from the use of extensively coated femoral components were promising. Nevertheless, anterior cortical perforations were also common, which may be related to more bowing of the femora among the Chinese patients. Caution must be exercised when inserting a long, straight, extensively coated femoral component. |
