ABSTRACT
We report the clinical and radiographic outcomes and complications of revision surgery using a cementless interlocking stem with an allograft-prosthesis composite (APC). This study included 11 patients with an average follow-up of 73 years. Of the 11 revisions, 1 was aseptic, 7 were septic, and 3 were periprosthetic femoral fractures. The mean Harris hip score improved from 25.6 points before surgery to 74.8 points at final follow-up. Osseous union at the proximal allograft-host bone junction occurred in 10 hips (90.9%) ; the greater trochanter did not unite in 4 of 7 hips (57.1%). Moderate and severe allograft resorption occurred in one hip each. Postoperative complications included 1 deep infection, 2 heterotopic ossifications, and 1 dislocation. Using an interlocking stem with an allograft-prosthesis composite in revision surgery provided acceptable results in the presence of circumferential massive bone deficiency of the proximal femur.
