We present a unique case of chronic peroneal tendon dislocation in a 47-year-old active duty military member with a 2-mo history of acute onset lateral ankle pain due to sports injury. Magnetic resonance imaging revealed superficial peroneal retinaculum (SPR) disruption, a flattened retrofibular groove, dislocation of the peroneus longus tendon, and a tear of the peroneus brevis tendon. The patient was managed operatively with fibular groove deepening, SPR reconstruction, peroneus brevis debridement, and peroneus longus tubulurization. No complications were observed during the intra- or perioperative periods. At their 3-mo follow-up, the patient reported near complete resolution of pain and the ability to ambulate without any brace or support. He returned to running and was able to deploy fit for full duty 4.5 mo from injury.
