Long-term results of cemented femoral revision surgery using second-generation techniques. An average 11.7-year follow-up evaluation.

Abstract

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