a Diagram of the modified Broström operation: The lateral stabilization is achieved by sewing the inferior extensor retinaculum to the periosteum of the lateral malleolus, where it is fixated by means of two suture anchors (modified after Bell SJ, Walthour CS, Provencher MT, Sittler DF. Chronic Lateral Ankle Instability: The Broström Procedure. Operative Techniques in Sports Medicine. 2005). b Arthroscopic view with prepared tip of the fibula. The first suture anchor is fixed and the second one is now also inserted. The next step is to pass the sutures through thus sewing the inferior extensor retinaculum to the periosteum of the lateral malleolus
