Abstract: Introduction: One of the rare causes of chronic ankle pain is a longitudinal tear of peroneus brevis tendon. Peroneus Brevis (PB) tears are thought to occur from both trauma and chronic instability, with and without subluxation former being more common. We report a case of chronic lateral ankle pain due to longitudinal tear of the peroneus brevis tendon without subluxation. Case report: A 51 years female, presented with pain and swelling behind the lateral malleolus on the left side. She had a twisting injury to the ankle before six months. The patient had pain with active resistance to eversion and single- legged standing. Magnetic Resonance image showed an irregularity at PB tendon and excessive fluid inside the synovial sheath, consistent with a partial-thickness tear. Surgical exploration of the peroneal tendon was performed. A longitudinal split of the peroneus brevis tendon about 3 cm long was noted at the level of retrofibular groove, the peroneus longus was intact and neither of the tendons was subluxated. The one part of the torn PB tendon which was frayed was trimmed distally and sutured to the main tendon using an absorbable suture. The lax superior peroneal retinaculum was plicated and fixed to the fibula using a suture anchor. The bony irregularities in the posterior aspect of lateral malleolus were smoothened to prevent further attrition tear. At one year follow up, the patient had no residual symptoms. Conclusion: Injury to the peroneal tendons is a frequently overlooked cause of persistent lateral ankle pain after trauma. High degree of clinical suspicion is important to diagnose the injuries. MRI serves as the key diagnostic tool. These tendon injuries need to be managed based on the extent and quality of the tears. Associated pathologies have to be addressed to prevent recurrence.
