Traumatic dislocation of the posterior tibial tendon (PTT) is a rare and often misdiagnosed injury. The limited number of cases, ambiguous results of initial imaging studies, and presence of symptoms similar to medial ankle sprains can contribute to unsuccessful long-term treatment. Current studies, although limited, report high rates of failure in nonoperative compared with operative treatment. We describe a 21-year-old male baseball player who experienced pain and mild swelling in his ankle after falling while running at full speed. After 5 months of continuous pain in the medial ankle, the patient was referred to our clinic and underwent suture anchor repair for treatment of PTT dislocation. At about 4 months postoperatively, no recurrence of symptoms was noted.
