Abstract Background: Revision total hip arthroplasty is frequently accompanied by bone loss. The purpose of this study is to evaluate mid- to long-term results of revision total hip arthroplasty for massive femoral bone loss using cementless modular, fluted, tapered stems.Methods: During the period of 2007 to 2015 at a single hospital, 34 hips (33 patients) underwent primary revision surgery with cementless modular, fluted, tapered stems due to massive bone loss, and patients with prosthetic joint infection (PJI) or tumours were excluded. The hips were revised with the LINK MP (Waldemar Link, Hamburg, Germany) prosthesis. Bone loss was categorized by the Paprosky classification for prosthesis loosening and Vancouver classification for peri-prosthetic fracture. All revision bearing surfaces were ceramic-on-ceramic (CoC). Clinical outcomes, radiographic outcomes and survivorship were evaluated.Results: The mean follow-up was 9.1±2.5 years (range, 5-13 years). The Harris hip score was 43.6±11.5 preoperatively and maintained at 86.5±6.6 at the time of latest follow-up (p<0. 05). The X-ray showed bone ingrowth fixation in 30 hips (88%), fibrous stable fixation in 3 hips (9%) and instability in 1 hip (3%). The average stem subsidence was 3.9±2.2 mm (range, 1 to 10 mm). The survivorship of prostheses with re-revision for any reason was 95% (95% CI, 12.0 to 13.0) at the 10-year follow-up. Three (9%) re-revisions were needed, including 1 for aseptic loosening, 1 for dislocation and 1 for infection.Conclusions: The mid- to long-term results of revision total hip arthroplasty with the cementless modular, fluted, tapered stem (LINK MP stem) are encouraging for massive femoral bone loss.

Introduction. The perforation and fracture of the femur during the removal of bone cement in revision total hip arthroplasty (THA) are serious complications. The ROBODOC system has been designed to selectively remove bone cement from the femoral canal, but results have not been reported yet. The purpose of our study was to evaluate the clinical and radiographic results of revision THA using the ROBODOC system for cement removal.Materials and Methods. The subjects comprised 19 patients who underwent revision THA using the ROBODOC system. The minimum duration of follow-up was 76 months (median, 109 months; range, 76–150 months). The extent of remaining bone cement on postoperative radiography, timing of weight bearing, and the complications were evaluated.Results. The mean Merle d’Aubigne and Postel score increased from 10 points preoperatively to 14 points by final follow-up. Bone cement was completely removed in all cases. Full weight bearing was possible within 1 week after surgery in 9 of the 19 cases and within 2 months in all remaining cases. No instances of perforation or fracture of the femur were encountered.Conclusions. Bone cement could be safely removed using the ROBODOC system, and no serious complications occurred. Full weight bearing was achieved early in the postoperative course because of circumferential preservation of the femoral cortex.
