RESULTS OF CEMENTED FEMORAL REVISION TOTAL HIP-ARTHROPLASTY USING IMPROVED CEMENTING TECHNIQUES

Seventy-nine consecutive femoral component revision total hip arthroplasties done in 73 patients from 1977 to 1983 using a distal intramedullary cement plug and a cement gun delivery system were evaluated to determine if improved results were obtained with newer cementing techniques. At a minimum 19-year followup interval, only 1 patient was not available for followup and 47 hips had minimum 10-year followup radiographs. The incidence of femoral rerevision for aseptic loosening was 9.5% for those hips with minimum 19-year followup and 5.4% for the entire group. The incidence of radiographic femoral failure (defined as a revision or definite or probable loosening) was 26.1% for those hips followed for a minimum of 10 years and 16.3% for the entire group. Compared with historical controls, these results represent an improvement over those reported with the use of earlier cementing techniques.
