Frailty in elderly patients undergoing arthroplasty increases the risk of postoperative complications,prolongs hospital stays,delays the rehabilitation process,and aggravates the economic burden.Frailty is a dynamic condition,and early detection and effective intervention can delay its progression.Therefore,early assessment of frailty status in patients is necessary.Currently,there are numerous frailty assessment tools,but the selection of these tools lacks a solid basis.This paper reviews the impact of frailty on the physical condition of elderly arthroplasty patients,as well as the content,application,advantages,and limitations of existing frailty assessment tools at home and abroad.Furthermore,it summarizes the problems in the process of frailty assessment and puts forward prospects,aiming to provide reference for the identification and assessment of frailty in elderly arthroplasty patients in the future.
