Osteoarthritis (OA) is a leading cause of disability and is more prevalent in women than men. Total joint arthroplasty is an effective treatment option for end-stage OA. We examined gender differences in utilization rates of total knee/hip arthroplasty in the Veterans Administration (VA) system.
The sample consisted of all VA patients for fiscal year (FY) 1999, 50 years of age or older, with or without the diagnosis of OA in any joint. We calculated the odds of patients undergoing total knee/hip arthroplasty adjusting for age, comorbidities, and presence of OA. We included the hospital site as a random effects variable to adjust for clustering.
Of the 1,968,093 (2.3% women) VA patients in FY 1999 who were 50 years of age or older, 329,461 (2.9% women) patients carried a diagnosis of OA. For women, 2-year adjusted odds of undergoing total knee or hip arthroplasty were 0.97 (0.83 to 1.14) and 1.00 (0.79 to 1.27), respectively.
Among patients potentially at risk for the procedure, men and women in the VA system were equally likely to undergo knee/hip arthroplasty.
骨关节炎（OA）是导致残疾的主要原因，在女性中比男性更为普遍。全关节置换术是终末期OA的一种有效治疗选择。我们研究了退伍军人管理局（VA）系统中全膝关节/髋关节置换术使用率的性别差异。
样本包括1999财政年度所有50岁及以上的VA患者，无论是否诊断出任何关节患有OA。我们计算了接受全膝关节/髋关节置换术患者的比值比，并对年龄、合并症和OA的存在进行了调整。我们将医院地点作为一个随机效应变量来调整聚类。
在1999财政年度1,968,093名（2.3%为女性）50岁及以上的VA患者中，329,461名（2.9%为女性）患者被诊断患有OA。对于女性，接受全膝关节或髋关节置换术的2年调整后比值比分别为0.97（0.83至1.14）和1.00（0.79至1.27）。
在可能有手术风险的患者中，VA系统中的男性和女性接受膝关节/髋关节置换术的可能性相同。
