Osteochondral Lesions of the Talus: Factors Predictive of Cartilage Integrity

Video Transcription

Video Summary

This study evaluated predictors of cartilage integrity in osteochondral lesions of the talus (OLT) in patients under 19. Reviewing 54 OLT cases, researchers assessed MRI and radiographic findings compared to arthroscopic cartilage status. MRI showed 95% sensitivity and 75% specificity overall, with better accuracy in patients with open distal tibial physes. Radiographic stage combined with MRI grading provided the highest reliability (AUC 0.95) in predicting cartilage disruption. Key independent predictors were physeal status, radiographic stage, MRI grade, and MRI-assessed cartilage integrity. Accurate prediction aids treatment planning and informs patient expectations for OLT management.
