LONG-TERM RESULTS OF THE MODIFIED EVANS REPAIR FOR CHRONIC ANKLE INSTABILITY

We treated 19 patients for chronic ankle instability with a modified E vans procedure. All patients were evaluated after an average follow up of 128 months with detailed questionnaire, clinical examination, and stress radiographs. Although the subjective results were reported as 8 excellent, 7 good, and 4 fair, residual pain was reported by 11 patie nts. There was a significantly increased number of osteophytes in the treated ankle joint, Stress radiographs demonstrated significantly imp roved stability in the operated ankle joint, Range of motion was signi ficantly reduced in hindfoot inversion. The results showed that the mo dified Evans procedure achieved sufficient joint stability at the expe nse of inversion range of motion, This reconstruction method apparentl y did not prevent the development of arthrosis.
