Background: Patient-Reported Outcomes Measurement Information System (PROMIS) is a newly developed patient-reported outcome that has been validated for the general foot and ankle population and has been applied to a variety of specific foot and ankle procedures. However, there is little data regarding clinical outcomes of patients at a more intermediate subgroup level. Thus, our study utilized PROMIS to provide normative data on pathologic conditions of the foot and ankle and assess postoperative outcomes based on anatomical location. Methods: Preoperative and 1-year postoperative PROMIS Physical Function (PF) and Pain Interference (PI) surveys were prospectively collected from a cohort of patients undergoing a foot and ankle procedure at a tertiary medical center. The cohort was split into forefoot (n = 136), midfoot (n = 44), hindfoot (n = 109), and Achilles (n = 62) procedure groups. Paired-t tests were used to compare preoperative versus postoperative outcomes within operative groups, while a 1-way analysis of variance (ANOVA) was used to detect differences in PROMIS scores between anatomic subgroups. Results: Paired t tests indicated that all 4 operative groups had significantly improved PROMIS PF and PI scores preoperatively versus 1 year postoperatively (all P < .001). One-way ANOVA demonstrated that there were no differences in postoperative PROMIS PF and PI scores between anatomic subgroups. A majority of patients achieved the minimal clinically important difference level of improvement in PROMIS PF and PI scores following surgery. Conclusions: All 4 operative groups had improvement in physical function and pain outcomes. Additionally, there were no differences in physical function and pain outcomes between operative groups. Level of Evidence: Level III, retrospective cohort study.
