The outcome of cementless total hip arthroplasty in haemophilic hip arthropathy.

Total hip arthroplasty (THA) in haemophilic arthropathy is reported to be less successful than in non-haemophilic indications. Although preliminary results are encouraging, the survival and functional outcome of cementless THA in haemophilia are not known. The aim of this study was to analyse mid-term results of cementless THA in haemophilia. Twenty-seven consecutive cementless THAs with 23 patients performed between June 1995 and June 2003 were reviewed. Mean age at time of operation was 36 years and mean follow-up period was 92 months (range, 60-156). Radiographic assessment was done for fixation of components, loosening, osteolysis, wear and bone responses around the implants. The factor requirements, amount of transfusion and complications associated with bleeding were studied. The mean preoperative Harris hip score changed from 57 to 95.9 at the latest follow-up. The survival at mean follow-up was 95.2%. One patient with osteolysis around acetabular cup was re-operated with bone-grafting and change of polyethylene liner. One loose cup was revised with a cemented cup. All other components were deemed stable at the latest follow-up. A standardized management protocol and dedicated team approach comprising of haematologist, physicians, physical therapist, nurses and coordinators is needed for excellent results. The present retrospective study shows that the functional results of cementless THA in haemophilia are satisfactory as it happens in osteoarthritic patients according to the current literature, mainly the younger. Thus, taking into account that the majority of haemophilia patients requiring a THA are relatively young, cementless THA is currently recommended.
