The clinical and radiological results of revision of low friction arthroplasty in the elderly.

We assessed 130 patients (138 hips) who were more than 70 years old at the time of revision arthroplasty and had a minimum follow-up of 4 years. The average follow-up was for 7 years 3 months. The clinical results were excellent or satisfactory in 95.6% of the cases. Systemic complications developed postoperatively in 47 patients (34.1%). Radiographically, 95.6% had a well-fixed, stable stem while 91.3% had a stable socket. Seven hips (5.1%) required re-revision. Analysis revealed a 96.5% survival of the arthroplasty at 8 years.
