In cases of ineffective conservative treatment or upon verification of terminal stages of osteoarthritis (Kellgren–Lawrence grades III and IV), total knee arthroplasty is recommended. Despite a high rate of favorable outcomes, 10%–30% of patients remain dissatisfied with the results of surgery. In this context, the use of a newly developed prehabilitation method in patients undergoing total knee arthroplasty may directly influence treatment outcomes by improving clinical and functional joint parameters and remarkably enhancing postoperative quality of life.</p> <p><bold>AIM: </bold>The work aimed to evaluate the effectiveness of a new prehabilitation method in patients undergoing total knee arthroplasty.</p> <p><bold>METHODS: </bold>A prospective, non-blinded, non-randomized, controlled, single-center interventional case–control study analyzed treatment outcomes in 64 patients with verified terminal-stage knee osteoarthritis who underwent total knee arthroplasty with the use of the developed prehabilitation method. Patients selected for participation in the study were allocated to two clinical groups: group 1 (control) and group 2 (main). Group 1 consisted of 33 patients, and group 2 included 31 patients. Comparative analysis and assessment of treatment effectiveness were performed 72 hours before surgery and subsequently 72 hours, 4 weeks, and 12 weeks after total knee arthroplasty using objective and subjective assessment methods.</p> <p><bold>RESULTS: </bold>Comparative analysis of treatment outcomes demonstrated significant differences and positive trends in clinical and functional parameters associated with the use of the developed prehabilitation protocol in both groups at all follow-up time points. Changes in the Western Ontario and McMaster Universities Osteoarthritis Index, Visual Analog Scale for pain, and the Two-Minute Walking Test 4 and 12 weeks postoperatively were more pronounced in the second group, with values of 24.0 and 15.0 points (<italic>p</italic> &lt; 0.001), 4.0 and 1.0 points (<italic>p</italic> &lt; 0.001), and 142.68 ± 15.91 m and 154.06 ± 11.73 m (<italic>p</italic> &lt; 0.001), respectively.</p> <p><bold>CONCLUSION: </bold>The proposed prehabilitation method for total knee arthroplasty promotes complete clinical and functional recovery of the knee joint within 12 weeks after surgery and leads to an improvement in patients’ quality of life in both the short and long term.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Остеоартроз (ОА) коленного сустава является распространённым деструктивно-дистрофическим заболеванием опорно-двигательной системы, выявляемым у 10–20% населения в мире, приводящим к ограничению трудоспособности в 8–21% случаев и требующим комплексного подхода в лечении. При этом в случае неэффективности консервативного лечения или при верификации терминальных стадий ОА (III и IV стадии по Kellgren &amp; Lawrence) пациентам рекомендуется тотальное эндопротезирование коленного сустава (ТЭКС). Несмотря на высокий процент положительных результатов данной операции, от 10 до 30% пациентов остаются неудовлетворёнными результатами ТЭКС. В связи с этим применение разработанного способа преабилитации пациентов при ТЭКС может непосредственно влиять на исход лечения в виде улучшения показателей клинико-функционального состояния сустава и приводить к существенному повышению качества жизни пациентов в послеоперационном периоде.</p> <p><bold>Цель. </bold>Оценка эффективности нового способа преабилитации пациентов при тотальном эндопротезировании коленного сустава.</p> <p><bold>Методы. </bold>В проспективном неослеплённом нерандомизированном контролируемом одноцентровом интервенционном исследовании типа «случай — контроль» были проанализированы результаты лечения 64 пациентов с верифицированным ОА коленного сустава терминальной стадии, которым был применён разработанный способ преабилитации при ТЭКС. Отобранные для участия в исследовании пациенты были распределены в две клинические группы: первую (контрольную) и вторую (основную). В первую группу вошли 33 пациента, во вторую — 31 пациент. Сравнительный анализ результатов и оценку эффективности проводили за 72 часа до операции, далее — через 72 часа, 4 и 12 недель после ТЭКС с использованием объективных и субъективных методов исследования.</p> <p><bold>Результаты. </bold>Сравнительный анализ результатов лечения и оценка эффективности применения разработанного способа преабилитации продемонстрировали статистически значимую разницу и динамику клинико-функциональных результатов у пациентов обеих групп на всех сроках наблюдения. Изменения показателей шкалы-опросника Western Ontario and McMaster University Osteoarthritis Index (WOMAC), визуально-аналоговой шкалы боли (ВАШ) и двигательного теста Two Minute Walking Test (2MWT) через 4 и 12 недель после операции были более выраженными во второй клинической группе пациентов: их значения составили 24,0 и 15,0 балла (<italic>p</italic> &lt; 0,001), 4,0 и 1,0 балла (<italic>p</italic> &lt; 0,001), 142,68 ± 15,91 и 154,06 ± 11,73 (<italic>p</italic> &lt; 0,001) соответственно.</p> <p><bold>Заключение. </bold>Применение<bold> </bold>предложенного способа преабилитации при ТЭКС позволяет обеспечить в течение 12 недель после операции полноценное клинико-функциональное восстановление коленного сустава и повышение качества жизни больных в краткосрочной и долгосрочной перспективе.</p></trans-abstract><kwd-group xml:lang="en"><kwd>total knee arthroplasty</kwd><kwd>knee joint</kwd><kwd>osteoarthritis</kwd><kwd>prehabilitation</kwd><kwd>satisfaction</kwd><kwd>quality of life</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тотальное эндопротезирование</kwd><kwd>коленный сустав</kwd><kwd>остеоартроз</kwd><kwd>преабилитация</kwd><kwd>удовлетворённость</kwd><kwd>качество жизни</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Preobrazhensky PM, Fil AS, Kornilov NN, et al.
