Chronic ankle instability causes intra-articular lesions, which may lead to secondary degenerative changes. The aim of this study was to evaluate the usefulness of the ankle arthroscopy for the evaluation and treatment of intra-articular pathologies associated with chronic ankle instability. Between January 2013 and March 2016, 25 anterior ankle arthroscopies with modi ed anatomic Broström-Duquennoy-Tourne lateral ankle ligaments reconstructions were performed. In arthroscopy all patients (100%) had some intra-articular pathologies: 75% synovitis or so tissue scarring, 19% - deep chondral defect, 56% - superficial chondral lesion, 52% - osteophytes, 24% - bony or avulsion fragments, 20% - loose bodies. All intra-articular pathologies were treated during procedure. In conclusion, it is recommended to perform anterior ankle arthroscopy in addition to lateral ankle ligament reconstruction to diagnose and treat intra-articular lesions.
