Treatment of Charcot neuroarthropathy (CN) of the foot and ankle remains challenging for both patients and surgeons. Nonoperative treatment with cast/orthosis immobilization has long been the main treatment, but surgical intervention has gained interest to improve poor long-term outcomes. Few long-term outcome studies exist on operative management of CN. A retrospective chart review was performed to analyze demographics, comorbidities, complications, and outcomes of operative management of CN. Patients were divided into two cohorts for analysis: limited surgical intervention (LSI) and reconstructive surgery (RS). Fifty-eight patients with CN treated surgically over 11 years were identified. Average follow-up was 46 months (range, 1 to 173 months). The mean age was 60.2 (range, 29 to 81) years, and the average body mass index was 34.3. Diabetes caused CN in 72.4 % (42/58) of patients. The LSI cohort (n = 32) had significantly higher rates of presenting infection (59.4 %; 19/32) and ulceration (87.5 %; 28/32) compared with the RS cohort (n = 26; 23.1 % [6/26] and 50 % [13/26], respectively). Rates of postoperative infection and ulceration were lower in the LSI group (25 % [8/32] and 34.4 % [11/32], respectively) than the RS group (42.3 % [11/26] and 42.3 % [11/26], respectively). The amputation rate for the LSI cohort was 21.9 % (7/32) compared with 23.1 % (6/26) for RS. This large, single-center study of operatively treated CN patients showed no significant difference between LSI and RS. This study provides data to help surgeons counsel patients on expected outcomes.
