LONG-TERM RESULTS OF CEMENTED FEMORAL REVISION SURGERY USING 2ND-GENERATION TECHNIQUES - AN AVERAGE 11.7-YEAR FOLLOW-UP EVALUATION

From a group of 43 hips in 41 patients, previously reported at an aver age of six years of follow-up evaluation, in whom second-generation ce menting techniques were used during femoral revision hip surgery, 38 h ips in 36 patients were rereviewed at an average follow-up period of 1 1.7 years (range, 118-172 months). The average age of the patients at the time of revision surgery was 52.8 years. Only four femoral compone nts (10.5%) required rerevision for aseptic loosening. Of those not re revised, the average Harris hip score at the time of follow-up evaluat ion was 81. Four additional hips (10.5%) had radiographic evidence of definite femoral component loosening. The survival of 90% of the impla nts of cemented femoral revision surgery and the 79% incidence of well -fixed femoral components for more than 11.7 years is attributed to th e improved cementing techniques and modern stem design.
