Tibialis Posterior Tendon Dislocation: A Review and Suggested Classification

Tibialis posterior tendon dislocation is a rarely described entity that is easily missed, resulting in delayed diagnosis and treatment. A review of the English published data on the topic showed inconsistency in the reporting of injuries and surgical management techniques, leading us to describe a novel classification system to guide treatment and future reporting. We also describe a case of tibialis posterior tendon dislocation in a professional volleyball player and our surgical technique for correction, including retromalleolar groove deepening.
