Background: The syndesmotic sprains account for 1% to 11% of all ankle injuries. Good understanding of the mechanism of injury, physical examination, new imaging techniques and ankle arthroscopy help to improve assessment and management of high grade ankle sprains with a normal mortise relationship. Methods: Eleven patients (9 men, 2 women) with average age of 26 years (22-38 years), who had syndesmotic sprain confirmed by ankle arthroscopy, were studied by the clinical symptoms and imaging assessments. The treatment results were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score. The mean duration of injury was 9 months, and the follow up was 12 months Results: Postoperatively, 7 ankles obtained excellent and 4 good results according to AOFAS score. Impingement of syndemotic scar tissue in the ankle joint was the main cause of persistent pain. These cases had no diastasis on the plain radiography and no obvious sign of instability during the ankle arthroscopy. In some cases, chondral softening and lesion were seen at the medial ridge of the Talus, which could be due to subtle instability and change in the ankle biomechanics. Conclusions: Syndesmosis ankle injury could produce chronic pain. Arthroscopic debridement, in the absence of ankle instability could be an effective tool.

Background: Persistent instability following an acute lateral ankle sprain has been reported to vary in incidence from 15% to 48%. Surgery is indicated when conservative management fails to produce a satisfactory functional outcome. Associated intraarticular lesions of talus or extraarticualr lesions like peroneus Brevis tendon injuries can impact the functional outcome of lateral ankle reconstruction. The aim of this study was to report our short-term experience and treatment of concomitant lesions in chronic lateral ankle instability.Methods: 18 patients, aged 21 to 45 years with recurrent ankle sprain and lateral ankle instability who had not responded to at least 3 months conservative treatment and had underwent direct lateral ligament repair were studied. All the patients received ankle arthroscopy and exploration of peroneus Brevis tendon before repair of anterior talofibular and calcaneofibular ligaments with 14 months (6-22 months) follow-ups. The cases were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score.Results: The mean duration of injury was 19 months. In the diagnostic ankle arthroscopy, 6 patients had some degree of talar chondral lesions, two requiring shaving and drilling. Preoperatively, all patients had poor scores (
