The Exeter™ Universal Hip in Patients 50 Years or Younger at 10–17 Years’ Followup

The Exeter™ Universal hip (Stryker Inc., Newbury, UK) has reported survival rates of 91.74% at 12 years in all patients with reoperation as an endpoint. However, its performance in younger patients has not been fully established. We reviewed survivorship and the clinical and radiographic outcomes of this hip system implanted in 107 patients (130 hips) 50 years old or younger at the time of surgery. The mean age at surgery was 42 years. The minimum followup was 10 years (mean, 12.5 years; range, 10–17 years) with no patients lost to followup. Twelve hips had been revised. Of these, nine had aseptic loosening of the acetabular component and one cup was revised for focal lysis and pain. One hip was revised for recurrent dislocation and one joint underwent revision for infection. Radiographs demonstrated 14 (12.8%) of the remaining acetabular prostheses were loose but no femoral components were loose. Survivorship of both stem and cup from all causes was 92.6% at an average of 12.5 years. Survivorship of the stem from all causes was 99% and no stem was revised for aseptic loosening. The Exeter™ Universal stem performed well, even in the young, high-demand patient.
