Key Points

  • To evaluate the radiologic progression of talar osteochondral lesions with subchondral cysts over a median of 98 months and analyze correlations with clinical outcomes.
  • Conducted an observational study over 98 months with standing ankle radiographs, computed tomography, and magnetic resonance imaging.
  • Assessed three categories of cyst changes: increased, not changed, and decreased.
  • Analyzed correlation between radiologic findings and clinical outcomes.
  • A substantial number of lesions showed radiologic stability or slow progression in cyst volume.
  • No cases progressed to osteoarthritis (OA).
  • No significant correlation found between cyst size changes and clinical symptoms.

Abstract

BACKGROUND: /y): (1) increased, (2) not changed, and (3) decreased. Factors were assessed using standing ankle radiographs, computed tomography, and magnetic resonance imaging. Additionally, the correlation between radiologic progression and clinical outcomes was analyzed. RESULTS: > .05). Notably, none of the cases progressed to OA.ConclusionA substantial number of OLT with subchondral cysts demonstrated radiologic stability, spontaneous reduction, or slow progression in cyst volume during long-term observation. We found no correlation between changes in cyst size and clinical symptoms.
