Ankle pain TENDONS: There is a mild amount of fluid surrounding the posterior tibialis tendon which is otherwise normal in course and caliber. The remaining extensor and flexor tendons are intact.LIGAMENTS: There is poor visualization of the anterior and posterior tibiofibular ligaments which may relate to prior injury. The anterior and posterior talofibular ligaments appear thinned but intact.ARTICULAR SURFACES AND BONE: Severe osteoarthritic changes affect the talocalcaneal articulation particularly anteriorly. There is subchondral cystic change and sclerosis along both portions of the joint. The posterior talocalcaneal demonstrates mild degeneration. The ankle mortise is intact. Small cystic changes are noted both in the lateral and medial aspects of the talar dome which are likely degenerative in nature. A possible loose body is seen within the posterior joint space.ADDITIONAL
1. Severe osteoarthritis of the talocalcaneal joint anteriorly.2. Absence of the anterior and posterior tibiofibular ligaments which may relate to prior injury.3. Minimal tenosynovitis of the posterior tibialis.
