INFLUENCE OF INCORRECT POSITION OF ANKLE-JOINT ENDOPROSTHESIS COMPONENTS ON CLINICAL AND FUNCTIONAL RESULTS IN PATIENTS AFTER ANKLE-JOINT TOTAL ENDOPROSTHESIS

The experiment of ankle-joint endoprosthesis in 26 patients is introduced. The importance of studies is predicted by the complexity of such surgery and inevitability of some or other implant location errors, which however do not result in dramatic consequences within three years of post-surgery monitoring. It is demonstrated that there is a possibility of eventual “functional autocorrection” of talar and tibial components under the influence of everyday bearing load subject to stable ligament apparatus, presence of movements in the scope of not less than 15 grades and absence (up to 5-7°) of sustained ankle joint equinus. Presence of primary component implantation defects and instability symptoms onset during endoprosthesis operation should be compared to clinical data. Misalignment of talar and tibial components by up to 1/3 of their surface, deviations from horizontal plane without severe pain syndrome, sufficient foot function for a specific patient requires further observation and correction of patient’s exercise, rather than urgent reimplantation of endoprosthesis or arthrodesis.
