Пациенты были разделены на две группы по типу использованного метафизарного фиксатора: втулки (группа 1) – 97 пациентов, и конусы (группа 2) – 37 пациентов. Оценку результатов операции проводили при выписке из стационара, через 6, 12, 24 месяца после оперативного вмешательства. Проводили анализ выживаемости эндопротеза методом Каплана - Мейера. Критическим событием считали реоперацию с полной заменой эндопротеза или его компонентов.</p></sec><sec><title>   Результаты</title><p>   Результаты: проведенный анализ выживаемости эндопротеза не выявил статистически значимых различий в группах втулок и конусов (критерий Log Rank (Mantel-Cox) р = 0,108). Разработан и внедрен алгоритм выбора метафизарного фиксатора при реТЭКС.</p></sec><sec><title>   Заключение</title><p>   Заключение: применение метафизарных втулок и конусов для замещения обширных костных дефектов при ревизионном эндопротезировании коленного сустава демонстрирует сходные результаты в среднесрочной перспективе. Внедрение алгоритмов выбора того или иного метода фиксации, учитывающие размер дефектов кости, возраст, уровень активности является шагом к улучшению результатов реТЭКС.</p></sec></abstract><trans-abstract xml:lang="en"><p>   The aim of this research was to study the immediate and long-term outcomes of revision total knee replacement (reTNR) using metaphyseal fixators (sleeves and cones), and to design the algorithm for choosing a metaphyseal fixator.</p><sec><title>   Material and methods</title><p>   Material and methods. The research involved 134 patients who underwent revision knee arthroplasty. The patients were divided into two groups according to the type of metaphyseal fixator used for their surgeries: sleeves (Group 1) – 97 patients, and cones (group 2) – 37 patients. The outcomes were evaluated at their discharge from the hospital, 6, 12, 24 months after surgeries. The implants survival was analyzed with the Kaplan - Meier estimate. Reoperation with the complete replacement of the implant or its components was considered a critical event.</p></sec><sec><title>   Results</title><p>   Results. The analysis of the implants survival rate revealed no statistically significant differences between the groups (Logrank (the Mantel-Cox) test, p=0.108). We designed the algorithm for metaphisal fixator selection in revision knee arthroplasty and implemented it into practice.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The implantation of metaphyseal sleeves or cones to replace extensive bone defects in reTNR surgeries presents similar outcomes in the mid-term. The introduction of the algorithm for choosing a metaphyseal fixator that takes into account the bone defect size, patient’s age and activity is a step towards improving the outcomes of reTNR.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревизионное эндопротезирование</kwd><kwd>коленный сустав</kwd><kwd>дефекты костей</kwd><kwd>алгоритм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>revision arthroplasty</kwd><kwd>knee joint</kwd><kwd>bone defects</kwd><kwd>algorithm</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Куляба Т.А., Корнилов Н.Н., Селин А.В., Разорёнов В.Л., Кроитору И.И., Петухов А.И., Каземирский А.В., Засульский Ф.Ю., Игнатенко В.Л., Сараев А.В.
