The Total Hip and Knee Arthroplasty Outcome Calculator (“Outcome Calculator”)

The Total Hip and Knee Arthroplasty Outcome Calculator estimates the chance of specific outcomes (such as a complication or death) after surgery. The estimates are based upon information about the patient’s prior health history. The estimates are calculated from models developed and validated using data from a large number of patients who had a primary elective total knee or hip arthroplasty. More information about the development and accuracy of the models have been published here:
