Radiologic Progression of Talar Osteochondral Lesions With Subchondral Cyst: A Median 98-Month Observational Study

This study investigates the long-term radiologic progression of nonoperatively managed cystic osteochondral lesions of the talus (OLT) and aims to identify predictors of cyst progression while examining the relationship between radiologic changes and clinical outcomes. The findings reveal that most patients experienced minimal change in cyst volume over a median follow-up of 98 months, with significant predictors of progression including larger initial cyst volume, bone marrow edema, and wall breakage; however, changes in cyst size did not correlate with clinical symptoms. Notably, none of the cases progressed to osteoarthritis.
