Subchondral cystic lesions are rarely found in or around the fetlock. Most documented cases occur in the stifle, where joint anatomy and load patterns make cyst formation more likely. When these lesions appear in the fetlock, they involve a high impact joint that is essential to daily movement and performance. That rarity is important, because it changes how the case is evaluated, treated, and managed for long term soundness. | Equine Performance Innovative Center: EPIC
