We describe surgeon-specific patient and procedure variability in a single center to determine how much variability exists between surgeons.


Data was analyzed from 2009 to 2013 at a single center. The total number of primary and revision hip and knee arthroplasty surgeries were quantified for each surgeon.


Surgeon caseload varied significantly, with the largest differences observed in primary TKA caseload. The largest patient differences were in regards to percentage of patients with diabetes mellitus amongst primary TKA patients


Significant differences in patient characteristics that could significantly impact outcomes after total joint arthroplasty were found amongst surgeons.
