Is it worth the risk? Frailty transition and complications following robotic total knee arthroplasty: A retrospective observational study

Frailty is an underutilized prognostic parameter in the geriatric population. Our study aimed to analyse the frailty incidence, its transition over 1 year and its influence on complication rate in patients undergoing elective robotic-assisted total knee arthroplasty (TKA). This was a retrospective study wherein an accumulation of deficits model was used to evaluate frailty of 435 consecutive patients undergoing primary unilateral Mako-assisted cemented TKA between January 2020 and July 2021. Based upon the preoperative values, participants were divided into three groups; non-frail (FI 0.20) states and were followed up for 1 year for change in frailty class, complications, re-admissions and mortality. A total of 435 patients were divided into three groups, non-frail (178), vulnerable (208) and frail (49). Improvement in mean frailty scores was seen in all three groups (P
