Open reconstructive procedures carry the disadvantages of subtalar joint stiffness and potential morbidity at the harvesting site. Recently, arthroscopic treatment of chronic lateral ankle instability has been proposed in order to minimize invasiveness, reduce operating time, and allow a faster rehabilitation period. The purpose of our paper was to assess the outcomes in terms of postoperative recovery and return to sport following arthroscopic reconstruction of lateral ankle instability.\n                    <jats:italic toggle=\"yes\">Methods:<\/jats:italic>\n                    Ninety patients with chronic lateral ankle instability were treated at our Department from 2004 to 2009. Mean age was 32.4 (range, 17 to 56) years. All patients underwent a four-step operative procedure, including: synovectomy, debridement of ATFL lesion borders, capsular shrinkage, and 21-day immobilization and nonweightbearing.\n                    <jats:italic toggle=\"yes\">Results:<\/jats:italic>\n                    Followup examination at an average of 4 years after surgery showed significant improvement of mean AOFAS scale (preoperative, 63.5; postoperative, 92.3;\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.001) and average Karlsson score (preoperative, 61.8; postoperative, 88.4;\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.001). Mean Tegner rating changed from 3.6 preoperatively to 4.9 at followup (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.001). Articular stability as assessed by Sefton scale significantly improved from a preoperative value of 4.0 to 1.8 (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.001). Most patients (96.6%) rated the success of their surgery as good to excellent.\n                    <jats:italic toggle=\"yes\">Conclusion:<\/jats:italic>\n                    Based on our results, we propose arthroscopic treatment as a suitable option for moderate chronic ankle joint laxity in patients with a complete ATFL lesion.\n                  <\/jats:p>\n                  <jats:p>Level of Evidence: IV, Retrospective Cohort Study<\/jats:p>","DOI":"10.3113\/fai.2012.0029","type":"journal-article","created":{"date-parts":[[2012,3,14]],"date-time":"2012-03-14T18:55:48Z","timestamp":1331751348000},"page":"29-36","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":34,"title":["Arthroscopic Four-Step Treatment for Chronic Ankle Instability"],"prefix":"10.1177","volume":"33","author":[{"given":"Alberto","family":"Ventura","sequence":"first","affiliation":[{"name":"U.O.S.D.
