The number of total knee replacements far exceeds the number of primary total hip replacements (THR) in Singapore. There is a paucity of data regarding patients who undergo THR in Singapore. This paper aimed to study the epidemiology and early postoperative outcomes of patients receiving primary THR in a single tertiary institution.
This is a retrospective study of all patients undergoing primary THR between January 2003 and December 2005. The following variables were analysed: patient demographics, surgical approach, mode of implant fixation, postoperative complications and functional outcomes using D'Aubigne and Postel scoring.
There were a total of 115 patients who underwent primary THR over a 36-month period. The mean age of patients was 55 (range 23-80) years. The male-to-female ratio was 1:2. The most common diagnoses in descending order were as follows: inflammatory arthritis, osteoarthritis, avascular necrosis, hip dysplasia and post-traumatic osteoarthritis. Patients were evaluated at a mean follow-up of 41 months, with 90.8 percent having excellent and good outcomes. There were no statistical differences between the surgical approach and implant fixation with regard to postoperative outcome.
In Asian patients, the three commonest aetiologies for degenerative hip arthritis were inflammatory arthropathies, primary osteoarthritis and avascular necrosis. Regardless of diagnosis, the patient groups had comparable functional outcomes following THR.
在新加坡，全膝关节置换术的数量远远超过初次全髋关节置换术（THR）的数量。关于新加坡接受THR手术患者的数据很少。本文旨在研究在一家三级医疗机构接受初次THR手术患者的流行病学情况及术后早期结果。
这是一项对2003年1月至2005年12月期间所有接受初次THR手术患者的回顾性研究。分析了以下变量：患者人口统计学特征、手术方式、植入物固定方式、术后并发症以及使用D'Aubigne和Postel评分评估的功能结果。
在36个月的时间里，共有115例患者接受了初次THR手术。患者的平均年龄为55岁（范围23 - 80岁）。男女比例为1:2。按降序排列，最常见的诊断依次为：炎性关节炎、骨关节炎、缺血性坏死、髋关节发育不良和创伤后骨关节炎。患者平均随访41个月，90.8%的患者结果为优或良。手术方式和植入物固定方式在术后结果方面无统计学差异。
在亚洲患者中，退行性髋关节炎最常见的三种病因是炎性关节病、原发性骨关节炎和缺血性坏死。无论诊断如何，THR术后各患者组的功能结果相当。
