摘要Introduction: Arthroscopic microfracture chondroplasty has been widely published as a treatment for osteochondral lesions of the talus (OLT). However, the clinical outcomes are inconsistent and prognostic predictors following arthroscopic microfracture for OLT are unknown. This study aimed to investigate clinical and magnetic resonance imaging (MRI) prognostic outcome predictors after microfracture chondroplasty treatment of OLT.
Methods: This is a retrospective study investigating patients who received arthroscopic microfracture for OLT between 2011 and 2021. The clinical function was evaluated using Foot and Ankle Outcome Scores (FAOS) and Visual Analog Scale. Pre- and postoperative MRI findings, including the size of the defect, lesion location, bone marrow oedema, cysts, effusion, and integrity of the cartilage were recorded. Multivariate regression models were used to evaluate factors affecting the clinical and radiological outcomes.
Results: Total of 21 patients was included in the study (14 men and 7 women) with a mean age of 57 years (range, 45-62). Mean follow-up was 4.2 years, and long-term postoperative and pre- and early postoperative MRI results were compared. The mean FAOS pain significantly improved from a baseline 41.7 ± 11.1 to 69.4 ± 16.7 postoperatively. The mean VAS improved from 7 to 3 postoperatively. Male gender (p=0.008), smoker (p=0.017), atraumatic (p=0.038), were risk factors for a poor outcome. However, there was no significant correlation between MRI parameters and clinical outcomes.
Conclusion: Arthroscopic microfracture provided satisfactory clinical outcomes. Gender, smoking history, and trauma history are independent predictors of clinical outcome, but no MRI parameters were identified as useful prognostic predictors.
