Abstract
ABSTRACTBackgroundChronic lateral ankle instability causes significant problems in physical activity and accelerates development of osteoarthritic changes. Many procedures were designed to reconstruct the anterior talo-fibular ligament (ATFL) in the treatment of chronic lateral ankle instability. Although most of them were effective, but brought big trauma and sacrifice of some tendons.ObjectiveTo design a minimally invasive ATFL reconstruction with partial peroneus brevis tendon and evaluate its clinical outcomes.Study designNonrandomized controlled clinical trial.Materials and methodsFrom 2004 to 2012, 29 patients of chronic lateral ankle instability were treated with minimally invasive ATFL reconstruction with partial peroneus brevis tendon. A 3 cm curved incision was made to explore the ATFL origin and its insertion. Half peroneus brevis tendon was taken to reconstruct the ATFL through the bone tunnel from the insertion of CFL to the insertion of ATFL in the fibular, and then fixed to ATFL insertion location on the talus. All patients were followed-up by radiology and clinical examination at least two years. Their ATFLs were always evaluated by standard stress X-ray examination and magnetic resonance imaging (MRI) prior to surgery and every 1 year after the operation. Functional results were assessed in terms of Karlsson score and the American Orthopaedic Foot and Ankle Society (AOFAS) anklehind foot score.ResultsThe average follow-up period was 57.9 months (24- 114 months). The majority of results (93.1%) were satisfactory. The mean Karlsson score improved from 41.7 prior to surgery to 88.6 and AOFAS from an average 47.2 preoperatively to 91.7 postoperatively at the final follow-up visit. Paired t-tests showed improvements of great significance (p < 0.01). The ligaments were proved be reconstructed well in all patients by MRI. It showed the negative talar tilt sign postoperatively by stress X-rays. There was no recurrence of lateral ankle instability.ConclusionThe minimally invasive ATFL reconstruction with partial peroneus brevis tendon has advantages of small trauma, good reconstruction and excellent clinical outcomes, thus, is a safe and effective method for the treatment of chronic lateral ankle instability.How to cite this articleChen Q, Tan X, Yuan C, Tao X, Cao H, Xu J, Tang K.
