The Total Hip and Knee Arthroplasty 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:

The Total Hip and Knee Arthroplasty Outcome Calculator for patients within the Veterans Health Administration (“Outcome Calculator”)

The Total Hip and Knee Arthroplasty Outcome Calculator estimates the chance of specific outcomes of a large number of patients of the Veterans Health Administration (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:
