Effect of Obesity on Clinical and Radiographic Outcomes Following Reconstruction of Stage II Adult Acquired XXXX .

@entity1 @entity85 @entity158 @entity28
BACKGROUND: Obesity is a known risk factor for the development of @entity85 ( @entity85 ), but @entity28 's effects on outcomes following @entity85 reconstruction are unknown. We hypothesized that @entity28 would negatively impact outcomes following joint-preserving stage II @entity85 reconstruction. METHODS: This retrospective study compared the outcomes of normal-weight (18.5 kg/m(2)  <= BMI < 25 kg/m(2)), overweight (25 kg/m(2)  <= BMI < 30 kg/m(2)), and @entity28 (BMI >=  30 kg/m(2)) @entity1 after @entity85 reconstruction. Clinical outcome measures included the Foot and Ankle Outcome Score (FAOS), Short-Form 12 (SF-12), and Numeric Rating Scale of @entity158 (NRS @entity158 ) administered preoperatively and at least 1 year postoperatively. Anteroposterior and lateral radiographs were taken preoperatively and at least 6 months postoperatively. Pre- to postoperative changes in outcome measures were assessed within BMI classes. Preoperative, postoperative, and pre- to postoperative changes in outcomes were compared among BMI classes. There were 41 normal-weight @entity1 , 39 overweight @entity1 , and 44 @entity28 @entity1 with a mean age of 56 years, FAOS follow-up of 2.9 years, and radiographic follow-up of 2.1 years. Demographics and reconstructive procedures were comparable among the 3 BMI classes. RESULTS: All outcomes significantly increased pre- to postoperatively in the 3 groups with the exception of the FAOS Symptoms subscale for normal-weight @entity1 (P = .340) and SF-12 Mental Component score for all 3 BMI classes (P > .999). Preoperatively, @entity28 @entity1 had more symptoms than normal-weight @entity1 , scoring 12 points lower on the FAOS Symptoms subscore (P = .008). @entity28 @entity1 also scored 11 points lower preoperatively on the SF-12 Overall score (P = .028) and had 31% greater @entity158 than normal-weight @entity1 (P = .003). There were no differences among the 3 BMI classes in any postoperative outcomes assessed. CONCLUSION: Although @entity28 @entity1 had significantly worse symptoms, overall health, and NRS @entity158 scores preoperatively, the short-term clinical and radiographic outcomes of stage II @entity85 reconstruction were similar for normal-weight, overweight, and @entity28 @entity1 . We suggest that joint-preserving reconstruction remains a viable alternative to fusion of the triple joint complex for the treatment of overweight and @entity28 stage II @entity85 @entity1 . LEVEL OF EVIDENCE: Level III, retrospective cohort study.
