Assessment of Evertor Strength Following Inferior Extensor Retinaculum Flap Ligamentoplasty in Patients With Chronic Lateral Ankle Instability

The primary aim of our study was to evaluate the strength ankle evertor muscles in patients who have undergone a lateral ligamentoplasty (which combined tensioning ligament group and reinforcing it with pediculated extensor retinaculum flap), using 2 measurement systems (isokinetic functional weightbearing test [MyoLux). Our hypothesis on treated side comparable that contralateral healthy side. This prospective included 23 had chronic instability underwent an inferior flap ligamentoplasty. Clinical results were assessed American Orthopaedic Foot & Ankle Society Karlsson scores. muscle analyzed, both ankles, isokinetic testing (gold standard) – open kinetic chain closed (MyoLux). Data interpreted Stata 14.0 software. score 88.1 ± 4.5, 89.6 4.0. Isokinetic tests did not show any significant difference between ankles one. Functional measuring inversion control at demonstrate differences ankles. As confirmed by good scores lack strength, this reports is satisfactory treatment instability. In addition, MyoLux reliable effective properly assess proprioception ankle.
