    Abstract:
    BACKGROUND: There is only sparse scientific data about the long-term effects of the Charcot foot on patients' lives and the clinical outcome. This study evaluates the long-term effects of diabetic Charcot foot. METHODS: A cross-sectional follow-up study of consecutive series of patients with Charcot foot referred to the University Hospital Diabetic Foot and Ankle Clinic between 1991 and 2002. RESULTS: Forty-one patients were referred with Charcot foot between 1991 and 2002. After an average follow-up of 8 years their overall mortality rate was 29% (12/41) and 29 patients (30 Charcot feet) have been followed more than 5 years. Sixty-seven percent of Charcot feet suffered at least one episode of ulceration and 50% (15/30) of affected feet had surgical treatment resulting in 29 operations. Simple exostectomy was successful in 62% of cases. The need for surgical management increased markedly 4 years after the diagnosis. Correct diagnosis within 3 months resulted in better functional outcome (AOFAS) and walking distance (p=0.006 and p=0.008, respectively). Lower SF-36 component scores in physical functioning, social functioning and general health perceptions were found when the study population was compared to the general population and chronically ill control subjects. CONCLUSIONS: Diabetic Charcot foot decreases patient's physical functioning and general health but does not usually affect mental health. Surgical management is often required with an increase 4 years post-diagnosis. A delay of diagnosis of more than 3 months was found to adversely affect the quality of life and functional outcome.
