Hypogonadism Is Associated With Increased Risks of Postoperative Complications Following Total Hip Arthroplasty

BackgroundDespite being a relatively common problem among aging men, hypogonadism has not been previously studied as a potential risk factor for postoperative complications following total hip arthroplasty (THA).MethodsIn total, 3903 male patients with a diagnosis of hypogonadism who underwent primary THA from 2006 to 2012 were identified using a national insurance database and compared to 20:1 matched male controls using a logistic regression analysis.ResultsHypogonadism was associated with an increased risk of major medical complications (odds ratio OR] 1.24, P = .022), urinary tract infection (OR 1.43, P < .001), wound complications (OR 1.33, P = .011), deep vein thrombosis (OR 1.64, P < .001), emergency room visit (OR 1.24, P < .001), readmission (OR 1.14, P = .015), periprosthetic joint infection (OR 1.37 and 1.43, P < .05), dislocation (OR 1.51 and 1.48, P < .001), and revision (OR 1.54 and 1.56, P < .001) following THA. A preoperative diagnosis of hypogonadism was associated with increased total reimbursement and charges by $390 (P < .001) and $4514 (P < .001), respectively.ConclusionThe diagnosis of hypogonadism is associated with an elevated risk of postoperative complications and increased cost of care following primary THA. Data from this study should influence the discussion between the patient and the provider prior to undergoing joint replacement and serve as the basis for further research.
