39-year-old male with significant ankle pain for 2 years and associated inflammation. TENDONS: No significant abnormality noted.LIGAMENTS: The anterior talofibular ligament appears slightly elongated and thin. The calcaneofibular ligament appears thickened. There are small foci of near-fluid signal intensity along the posterior talofibular ligament. This constellation of findings may represent prior injury to the lateral collateral ligament complex. The distal tibiofibular syndesmotic complex appears intact. There is loss of the normal fatty striation of the deep component of the deltoid ligament which may reflect prior trauma. There is a 1 cm ossicle along the anterior inferior margin of the medial malleolus likely reflects old trauma as well.ARTICULAR SURFACES AND BONE: There are 1.5-2 cm ossicles along the dorsal aspect of the talonavicular joint which may reflect old trauma. There is severe osteoarthritis of the talonavicular joint. Relatively mild osteoarthritis affects the tibiotalar joint. ADDITIONAL
Findings suggestive of prior trauma to the ankle as described above with severe osteoarthritis of the talonavicular joint and relatively mild osteoarthritis of the tibiotalar joint.
