Background: Chronic instability is a common complication of lateral ankle sprains. Furthermore, patients often have unrecognized associated lesions affecting the and subtalar joints. Many stabilizing surgical techniques been described, each with variable results. This article reports long-term results ligamentous retensioning combined reinforcement using an extensor retinaculum flap. Patients Methods: retrospective, multicenter study. One hundred fifty cases were reviewed at mean follow-up 11 years. Functional assessed Karlsson score. Pre- postoperative radiological assessment employed stress x-rays to measure varus tilt anterior drawer Van Dijk classification grade osteoarthrosis. The Stata 10 program was used for statistical analysis. Results: A thorough preoperative workup identified joint in 30% cases. At review, 93% satisfied. Residual present only 4.8%. Radiographic analysis both ankles revealed differential 0.12° 0.17 mm. There no deterioration articular surfaces after years follow-up. Conclusion: To authors' knowledge, this largest series reported such technique addressed without sacrificing peroneal tendons. It protected against progression posttraumatic arthrosis provided superior other terms patient satisfaction residual instability. Level Evidence: IV, Retrospective Case Series
