Results of the cementless Plasmacup in revision total hip arthroplasty: a retrospective study of 72 cases with an average follow-up of eight years

Introduction: During revision total hip arthroplasty (THA), the surgeon commonly faces deficient proximal femoral bone. In this situation, distal fixation of the prosthesis is required. The aim of the current retrospective study is to assess the clinical and radiographic mid-term outcome of revision total hip arthroplasty using a modular uncemented, tapered, grit-blasted, distal straight stem system. Methods: This retrospective study included 70 femoral revisions that were performed in 67 patients using the device of interest. All patients were operated on via an extended trochanteric osteotomy. 60 revisions were performed as 1-stage (12 infected) and 10 as 2-stage (all infected) revisions. At 3 months postoperatively and at final follow-up, patients were assessed radiographically for the presence of osteolysis and for distal integration. Results: The mean follow-up time was 4.3 (2.0-7.6) years. 4 patients had a removal of at least 1 prosthetic component. Stem survival for any reason was 92% after 5 years (95% confidence interval [CI], 83%-100%). With aseptic loosening of the stem as the endpoint of interest, survival after 5 years was 96% (95% CI, 88%-100%). A postoperative subsidence rate of 14.7% was found. No perioperative femoral fractures were found in the current patient series. Conclusions: This study showed excellent mid-term survival and good clinical and radiographic outcomes in patients who had undergone revision THA with a modular uncemented, tapered, straight design.

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.

Background: Cementation of polyethylene liners into well-fixed cementless metal shells has become an option during revision total hip arthroplasty (THA). We report the results of cementing a dual-mobility (DM) component into a stable acetabular shell in high-risk patients undergoing revision THA. Methods: A single-centre series of 10 patients undergoing revision THA with a DM cup cemented into an existing well-fixed shell between 2012 and 2016 were retrospectively reviewed. Failure due to aseptic loosening or instability and implant survival at last follow-up were analysed. The average age was 79.2 years and mean follow-up was 3.5 years. Indications were recurrent hip dislocation in 8 cases and intraoperative instability with moderate abductor insufficiency in 2 cases. In cases with recurrent dislocation, the aetiology of instability was classified by Wera type. Results: At the latest follow-up, Harris Hip Scores had improved from 49.3 preoperatively to 71.3 postoperatively ( p = 0.098). In the 8 patients with recurrent dislocation, 4 cases (50%) had an unclear aetiology (Wera type 6), 2 (25%) abductor deficiency (Wera type 3) and 2 (25%) late polyethylene wear (type 5). Postoperative recurrent dislocation occurred in 1 hip (10%). No cases of intraprosthetic dislocation, aseptic loosening of the previous shell or dissociation at the cement-cup interface were identified. Conclusion: Although the follow-up of this series is short, cementation of a DM cup into a previous well-fixed socket seems to be a viable option to treat and prevent instability after revision THA, without providing constraint at the cement-cup interface.

Cement Removal

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.
