The purpose of this study is to evaluate the medical and surgical postoperative complication profile in patients with PD and we hypothesize they will be significantly increased compared to control. Methods A search of the entire Medicare database from 2005-2011 was performed using International Classification of Disease version 9 (ICD-9) codes to identify 86,976 patients who underwent primary THA with PD including bipolar (5,626), depression (82,557), and schizophrenia (3,776).
