Twenty-one patients (21 hips) underwent cementless total hip replacement surgeries for previous acetabular fractures. The mean age at the time of hip replacement was 52 years (range, 23-78 years). The mean follow-up was 65 months (range, 48-104 months). One hip required revision of the stem secondary to a periprosthetic femur fracture from a fall at 3 months after surgery, good to excellent clinical rating was achieved and maintained in 19 hips. Radiographic evaluation demonstrated stable cup and stem fixation in 17 and 15 hips. Only 1 patient with radiographic loosening of the components was sufficiently symptomatic. The results in this series appeared slightly better than those reported previously in hip replacements done with cement at comparable medium-term follow-up. The mechanical failure rates remained high in this patient population: 19% for the cups and 29% for the stems.
