The Charcot Reconstruction Preoperative Prognostic Score's Evaluation with Complication Rate and Functional Outcome
Background:
Charcot's neuroarthropathy (CN) treatment is still controversial, and the results are controversial. Owing to patient comorbidities, surgical intervention carries a high risk of complications. Thus, foreseeing the possible results of planned treatment is crucial. We retrospectively evaluated the Charcot Reconstruction Preoperative Prognostic Score (CRPPS) in patients with surgically treated CN.
Methods:
Twenty-two feet of 20 patients were included in the study. Two groups were formed according to their CRPPS. Twelve patients with values less than 4 were defined as group A, and eight patients with values of 4 or greater were defined as group B. Mean follow-up was 61 months (range, 5-131 months). Groups were compared according to American Orthopaedic Foot and Ankle Society (AOFAS) scores, Foot and Ankle Disability Index (FADI) scores, and complication rates.
Results:
Group A and B mean AOFAS scores were 76.83 (range, 71-85) and 70.5 (range, 20-85), respectively. All of the patients were improved according to AOFAS and FADI scores, but no correlation was found with the CRPPS. None of the group A patients required additional intervention, but five patients in group B underwent revision surgery. No amputations were performed.
Conclusions:
The CRPPS is focused on feasibility. The data needed to fill the scoring system is easily obtainable from medical records even retrospectively, and the score is helpful to predict a patient's outcome after CN-related surgery. Herein, CRPPS values of 4 or greater were related to high complication rates and lower functional outcomes.
