Severe osteochondral lesions associated with loose bodies may lead to early arthritis and chronic pain if diagnosis and treatment are delayed. Most common symptoms are pain and swelling, with less common stiffness and locking. Etiology is not known, with many suggesting post-traumatic or associated with longer term ankle instability. Initial conservative therapy is appropriate for lesions grades I-III. Our patient presented with imaging concerning for a grade IV lesion, which would be an indication for surgical intervention.
