The patients were randomly assigned to the robotic arthroplasty group (30 individuals) or the manual arthroplasty group (30 individuals). Evaluation was performed 6 months postoperatively using clinical (VAS, ROM), radiological (LDFA, MPTA, rotational parameters), and stabilometric indicators. High-precision scales and 3D modeling were used to analyze the mass of the cement mantle.</p> <p><bold>RESULTS: </bold>The robotic technique demonstrated superiority in the precision of component positioning: deviations of less than 1° in LDFA and MPTA were recorded in 93% and 66% of patients, respectively (compared with 23% and 9.4% in the manual technique group). The mean range of motion was 109° versus 106.2°, and the VAS pain score was 3.7 versus 4.2. The robotic technique ensured lower variability in cement mass and cement mantle thickness.</p> <p><bold>CONCLUSION: </bold>Robotic arthroplasty surpasses the manual technique in terms of component positioning precision, cement mass distribution, and functional outcomes. Despite the absence of statistically significant differences (<italic>p</italic> &gt; 0.05), the observed trends in favor of the robotic approach render it preferable for widespread clinical application.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Рост числа операций эндопротезирования коленного сустава и связанных с ними осложнений подчёркивает необходимость внедрения технологий, повышающих прецизионность установки компонентов эндопротеза и улучшение функциональных исходов.</p> <p><bold>Цель. </bold>Оценить прецизионность роботизированного метода эндопротезирования коленного сустава в сравнении с мануальным методом на основе клинических данных, рентгенологических и стабилометрических показателей.</p> <p><bold>Методы. </bold>В когортное контролируемое интервенционное одноцентровое проспективное выборочное рандомизированное неослеплённое исследование включены 60 пациентов (возраст — 18–75 лет) с остеоартритом коленного сустава III стадии. Пациенты были случайным образом разделены на группы роботизированной (30 человек) и мануальной артропластики (30 человек). Оценка проводилась через 6 месяцев после операции с использованием клинических (ВАШ, ROM), рентгенологических (LDFA, MPTA, ротационные параметры) и стабилометрических показателей. Для анализа массы цементной мантии использовались высокоточные весы и 3D-моделирование.</p> <p><bold>Результаты. </bold>Роботизированная методика показала преимущество в прецизионности установки компонентов: отклонение менее 1° по LDFA и MPTA зафиксировано у 93 и 66% пациентов соответственно (в сравнении с 23 и 9,4% в группе мануальной техники). Средний объём движений составил 109° против 106,2°, а уровень боли по ВАШ — 3,7 против 4,2. Роботизированная техника обеспечила меньшую вариативность массы цемента и толщины цементной мантии.</p> <p><bold>Заключение. </bold>Роботизированная артропластика превосходит мануальную в аспектах прецизионности установки компонентов, распределения массы цемента и функциональных исходов. Несмотря на отсутствие статистически значимых различий (<italic>p</italic> &gt;0,05), тенденции в пользу роботизированного подхода делают его предпочтительным для широкого клинического применения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>robotic arthroplasty</kwd><kwd>knee arthroplasty</kwd><kwd>robot</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>роботизированное эндопротезирование</kwd><kwd>артропластика коленного сустава</kwd><kwd>робот</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Abramoff B, Caldera FE.
