AbstractThe cost of health care in the United States has been rising steadily during the past 10 years. Total joint arthroplasty, a commonly performed orthopaedic procedure, accounts for approximately $10 billion dollars per year. The objective of this study was to perform a clinician-oriented cost analysis of primary and revision hip and knee arthroplasty. Twenty-five consecutive cases each of total knee arthroplasty, total hip arthroplasty, revision total knee arthroplasty, and revision total hip arthroplasty were analyzed. The length of stay and number of minutes spent in the operating room were significantly higher for the patients with revision hip surgery than for the other groups. The total charges for the prosthesis in the 4 groups exceeded 40% of the total charges for the procedure. Primary hip and knee surgery had similar billed costs, and work for revision hip surgery has a significantly higher billed cost than physician's work. The implant selection process by an orthopaedic surgeon performing arthroplasty of the hip and knee needs to include economic aspects.
