Image Interpretation: High grade tear of right proximal adductors at pubic tubercle and body, involving at least 75% of adductor longus tendon, fibrocartilage, and muscle, extending to anterior third of adductor brevis.
Normal appearing origin of left adductor longus and brevis and pubic tubercle and body.
Teaching Pearl: The adductor longus is the most commonly injured adductor during sport, in part because of its long lever arm, high eccentric load, and relatively vulnerable pubic bone attachment. Ultrasound should evaluate the proximal adductor tendon origin, fibrocartilaginous enthesis, muscle extension, and adjacent adductor brevis involvement. Reporting the percent of tendon involved, retraction, hematoma, and muscle involvement can help guide prognosis and surgical referral decisions.
