Complications of total hip arthroplasty following solid organ transplantation.
PURPOSE: Solid organ transplants (SOT) continue to increase with recipients living longer than ever before. The lifelong immunosuppression in these patients also may place them at increased risk for postoperative complications. The efficacy of total hip arthroplasty (THA) in this patient population is undisputed but previous studies investigating the complication profiles in these patients often are underpowered to identify rare complications as well as make comparisons between individual organs. The purpose of this study was to use a large database to compare complications of a combined SOT cohort as well as each individual organ to a control population. METHODS: A search of the entire Medicare database from 2005 to 2011 was performed using International Classification of Disease version 9 (ICD-9) codes to identify patients who underwent THA after one or more solid organ transplants. A large cohort of patients served as a control with minimum 2-year follow-up. Post-operative complications at 30-day, 90-day, and overall time points were investigated. RESULTS: Transplant patients carry more medical comorbidities and are prone to increased medical complications, dislocations (OR 1.45, p < 0.001), need for irrigation and debridement (OR 1.90, p < 0.001), and periprosthetic infection (OR 1.69, p < 0.001) compared to patients without SOT. Total hip arthroplasty after renal transplantation has the worst complication profile of the individual organs whereas lung and pancreas transplants were no different than control with regard to overall surgical complications. CONCLUSIONS: The complications of THA after SOT vary by individual organ and these results may aid in patient selection and perioperative patient counseling.
