This retrospective study explored the relationship between the volume of total hip arthroplasties (THA) and postoperative mortality and early complications from a single institution. One thousand hip arthroplasties in 932 patients were identified during a 1-year period, which included 786 primary and 214 revision hip arthroplasties. The postoperative 6-month combined medical and orthopedic complication rate for primary and revision THA was 7.9% and 16.5%, respectively. The 6-month mortality rate for the overall group was 0.5% (5 deaths), for the primary hips was 0.4% (3 deaths), and for the revision hip was 0.9% (2 deaths). The mortality and complication rates of many surgical procedures, including joint arthroplasties, are inversely related to hospital and surgical volume. The reduction in complication rate, however, approaches a plateau and does not improve regardless of an increase in the surgical and hospital volume.
