The relevance and increasing number of PKR are confirmed by data from various national registers.</p><p><bold>The aim of the study </bold>was to research the early functional results of PKR and to analyze the complications at various stages of the postoperative period.</p><p><bold>Material and Methods. </bold>Study design: a single-center prospective study. The results of 90 operations of PKR in the period from March 2018 to April 2020 are presented. Assessment of knee function and quality of life of patients was performed according to three scalesquestionnaires: KOOS, WOMAC, SF-36, which were filled in preoperatively and then at 3, 6, 9, 12, 18 months. after surgery. Patients within the reporting period provided X-rays and filled in the scales at the face-to-face examination and at remote contact.</p><p><bold>Results.</bold> The most significant improvement of quality of life and median values of the functional results observed after 3 months, and after 18 months. After replacement the best median functional outcome scales KOOS, WOMAC, SF-36 — 79,4 (73,6–84,3); 27,1 (24,8–30,6); 89,1 (85,3–92,6) compared with the functional results obtained before surgery 32,3 (22,8–38,4); 73,6 (63,6–78,8); 35,2 (31,3–42,1); p = 0,027; p = 0.023; p = 0,028, respectively. A negative correlation was obtained between BMI and functional outcome (p = 0.027, R = -0.7).</p><p><bold>Conclusion.</bold> PKR allowed us to achieve an improvement in the quality of life and functional results already in the early postoperative period (from 3 to 18 months after the operation). The improvement of the operating technique, the analysis of errors and the regularity of the performed PKR will improve the results of PKR and minimize the number of complications.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Среди методов хирургического лечения ранних стадий медиального гонартроза все чаще используется одномыщелковое эндопротезирование коленного сустава (ОЭКС). Постоянно увеличивающееся число выполняемых ОЭКС медиального отдела подтверждается данными различных национальных регистров артропластики.</p><p><bold>Цель исследования </bold>— оценить ранние функциональные результаты одномыщелкового эндопротезирования медиального отдела коленного сустава и проанализировать осложнения на различных этапах послеоперационного периода.</p><p><bold>Материал и методы. </bold>Дизайн исследования: одноцентровое проспективное. Представлены результаты 90 операций ОЭКС медиального отдела в период с марта 2018 по апрель 2020 г. Оценку функции коленного сустава и качества жизни пациентов проводили с использованием шкал-опросников: KOOS, WOMAC, SF-36 до операции и через 3, 6, 9, 12, 18 мес. после ее выполнения. Оценку функционального состояния пациентов по KOOS и WOMAC высчитывали в процентах от максимально возможной суммы баллов по каждой из шкал.</p><p><bold>Результаты. </bold>Наиболее значимое улучшение качества жизни и функционального состояния зарегистрировано через 3 мес., а через 18 мес. после эндопротезирования получены наилучшие результаты: KOOS — 79,4% (73,6–84,3); WOMAC — 27,1% (24,8–30,6); SF-36 — 89,1 баллов (85,3–92,6) по сравнению состоянием до операции 32,3% (22,8–38,4) р = 0,027; 73,6% (63,6–78,8) р = 0,023; 35,2 баллов (31,3–42,1) р = 0,028 соответственно. Получена отрицательная корреляция между ИМТ и функциональным исходом (р = 0,027, R = -0,7). В послеоперационном периоде выявлены осложнения у 8 пациентов, из которых 3 пациентам выполнено ревизионное оперативное вмешательство, а 5 — проводилось консервативное лечение.</p><p><bold>Заключение.</bold> ОЭКС медиального отдела позволяет добиться улучшения качества жизни и функционального состояния уже на ранних сроках (от 3 до 18 мес.) после операции. Совершенствование операционной техники, анализ ошибок и регулярное выполнение хирургом операций ОЭКС позволят улучшить результаты и минимизировать количество осложнений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>partial knee replacement</kwd><kwd>medial knee compartment</kwd><kwd>medial gonarthrosis</kwd><kwd>early results</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>одномыщелковое эндопротезирование</kwd><kwd>медиальный отдел коленного сустава</kwd><kwd>медиальный гонартроз</kwd><kwd>ранние результаты</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">государственное бюджетное финансирование</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
