The purpose of the present study was to review the general and hip-specific factors potentially compromising total hip replacement (THR) in patients with Down\u2019s syndrome, as well as to summarise both the surgical techniques that may anticipate the potential adverse impact of these factors and the clinical results reported to date. A search of the literature was performed, and the findings further informed by the authors\u2019 clinical experience, as well as that of the hip replacement in Down Syndrome study group. The general factors identified include a high incidence of ligamentous laxity, as well as associated muscle hypotonia and gait abnormalities. Hip-specific factors include: a high incidence of hip dysplasia, as well as a number of other acetabular, femoral and combined femoroacetabular anatomical variations. Four studies encompassing 42 hips, which reported the clinical outcomes of THR in patients with Down\u2019s syndrome, were identified. All patients were successfully treated with standard acetabular and femoral components. The use of supplementary acetabular screw fixation to enhance component stability was frequently reported. The use of constrained liners to treat intra-operative instability occurred in eight hips. Survival rates of between 81% and 100% at a mean follow-up of 105 months (6 to 292) are encouraging. Overall, while THR in patients with Down\u2019s syndrome does present some unique challenges, the overall clinical results are good, providing these patients with reliable pain relief and good function.<\/jats:p><jats:p>Cite this article: Bone Joint J 2013;95-B, Supple A:41\u20135.<\/jats:p>","DOI":"10.1302\/0301-620x.95b11.32901","type":"journal-article","created":{"date-parts":[[2013,11,1]],"date-time":"2013-11-01T13:44:23Z","timestamp":1383313463000},"page":"41-45","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":21,"title":["Surgical challenges and clinical outcomes of total hip replacement in patients with Down\u2019s syndrome"],"prefix":"10.1302","volume":"95-B","author":[{"given":"M.
