Objective: The purpose of this study is to analyze arthroscopic findings in Maisonneuve lesions treated by arthroscopically-assisted reduction and percutaneous fixation. Materials and Methods: We evaluated the registry of patients operated on between May 2013-January 2019 with acute Maisonneuve lesions, treated by arthroscopically-assisted reduction and percutaneous fixation. We analyzed arthroscopic findings (chondral or osteochondral lesions, intraarticular loose fragments, injury of the distal tibiofibular joint with or without instability, and injury of the deltoid ligament with or without medial instability). Results: 13 ankles in 13 patients were evaluated. 100% evidenced injury of the anterior distal tibiofibular ligament and instability of the distal tibiofibular joint. 92.30% had medial structure injuries, 76.9% with complete deltoid ligament injury with instability and 15.38% with medial malleolus fractures. In 1 patient (7.69%), no medial injury was evidenced. 84.61% of patients presented chondral or osteochondral lesions. 53.84% (7 patients) of cases had intraarticular loose fragments. Conclusion: Maisonneuve lesions are a consequence of high-energy trauma and present with a high incidence of intraarticular structure injuries (ligaments and articular surface). Arthroscopy is a very useful tool to identify and treat intraarticular injuries, which would otherwise not be recognized.
