Orthopedic frailty risk stratification (OFRS): a systematic review of the frailty indices predicting adverse outcomes in orthopedics.

Background: With a growing number of elderly patients requiring elective and non-elective procedures, frailty-based preoperative risk stratification is an emerging tool in orthopedic surgery to minimize adverse postoperative outcomes. This paper sought to understand the current literature regarding preoperative Orthopedic Frailty Risk Stratification (OFRS) and describe the disparate frailty indices and their capabilities for discrimination in predicting adverse postoperative outcomes.

Methods: A literature search was conducted in Pubmed, Cochrane, and Scopus for articles published during or prior to February 2024 assessing frailty following surgery for orthopedic pathologies.
