Modified frailty index is a useful predictor for complications following total elbow arthroplasty in all populations

Higher mFI-5 scores in patients aged 50 and older were associated with worse postoperative outcomes including non-home discharge, transfusion likelihood, and prolonged hospitalization. Similar trends were observed in both the 65 + and 80-89-year-old cohorts regarding the risk of non-home discharge, however, higher mFI-5 scores in these older groups did not have an increased likelihood of postoperative transfusion or prolonged hospital stay.
