Clinical prediction models for patients undergoing total hip arthroplasty: an external validation based on a systematic review and the Dutch Arthroplasty Register

Abstract

Several prediction models have been developed for hip and knee arthroplasty, aiming to predict the probability of an outcome after surgery . These predicted probabilities can provide valuable information to patients and clinicians as an aid in clinical decision-making and expectation management. However, existing prediction models for arthroplasty are often not suitable for use in clinical practice, due to either poor predictive performance or lack of external validation . External validation plays an important role in assessing the generalizability and performance of these models in a differe
