Machine learning-based prediction of postoperative frailty progression in geriatric hip arthroplasty patients: a retrospective cohort study
Frailty is a significant geriatric syndrome that adversely affects postoperative recovery in older patients undergoing hip arthroplasty. This study aimed to identify distinct frailty trajectories in older adults after hip arthroplasty, develop and validate a machine learning-based prediction model for these traje...
