External Validation of a Prognostic Model for Predicting Nonresponse Following Knee Arthroplasty.

ABSTRACT:

Background

Instruments designed to predict the extent of pain and function following knee arthroplasty (KA) recovery has strong potential to guide patients and clinicians in shared decision making. Our purpose was to test the external validity of a recently developed prognostic instrument designed to estimate the probability of nonresponse following KA.

Methods

We used data from the Osteoarthritis Initiative (OAI), a 9-year multisite National Institutes of Health study designed to examine the natural history of knee osteoarthritis in 4796 subjects. A total of 427 subjects underwent KA over the study period. Dowsey et al examined the prognostic role of obesity, general mental health, pain and function, and Kellgren and Lawrence knee osteoarthritis grades. Calibration of the p
