This situation necessitates an active search for effective conservative treatment methods capable of slowing disease progression and delaying the need for total knee arthroplasty (TKA). This article presents a detailed analysis of the current role of intra-articular administration of hyaluronic acid (HA) preparations in OA therapy. The necessity of personalized treatment approach based on OA phenotyping is justified, and consensus recommendations from the European expert group EUROVISCO are provided, defining specific clinical situations for rational use of HA. Special attention is given to cross-linked HA drugs that, due to their prolonged residence time in the joint, provide both long-lasting mechanical (shock absorption) and delayed biological (viscoinduction) effects. Advantages of the innovative CHAP technology implemented in Flexotron Cross® drug are discussed, allowing achieving faster and more pronounced analgesic effect compared to other cross-links. Data demonstrating the impact of course application of HA on significantly postponing TKA timelines are presented, providing patients with opportunities for lifestyle modification, particularly weight loss, which substantially reduces perioperative risks. Additionally, the issue of contralateral joint OA progression after unilateral TKA is addressed, discussing protective role of HA in preventing its damage by reducing pain and normalizing movement patterns.</p></abstract><trans-abstract xml:lang="ru"><p>Распространенность остеоартрита (ОА) коленных суставов (КС), демонстрирующая неуклонный рост в последние десятилетия, представляет собой серьезную клиническую и экономическую проблему. Подобная ситуация обусловливает активный поиск эффективных методов консервативного лечения, способных замедлить прогрессирование заболевания и отсрочить необходимость тотального эндопротезирования КС (ТЭКС). В статье приводится детальный анализ современного места внутрисуставного введения препаратов гиалуроновой кислоты (ГК) в лечении ОА. Обосновывается необходимость персонализированного подхода к лечению, основанного на фенотипировании ОА, предлагаются консенсусные рекомендации Европейской консенсусной группы по вискосупплементации – EUROVISCO, которые определяют конкретные клинические ситуации для рационального применения ГК. Особое внимание уделяется препаратам ГК с поперечными межмолекулярными связями (кросс-линкам), которые благодаря увеличенному времени нахождения в суставе обеспечивают как продолжительный механический (амортизационный), так и отсроченный биологический (вискоиндукцию) эффекты. Рассматриваются преимущества инновационной технологии Crosslinked Hyaluronic Acid Platform – CHAP, реализованной в препарате Флексотрон Кросс®, позволяющей достичь более быстрого и выраженного эффекта по сравнению с другими кросс-линками. Приводятся данные, демонстрирующие влияние курсового применения ГК на возможность значительно отсрочить сроки проведения ТЭКС, предоставляя пациентам возможность для модификации образа жизни, в частности для снижения массы тела, что существенно уменьшает периоперационные риски. Дополнительно освещается проблема прогрессирования ОА в контралатеральном суставе после одностороннего ТЭКС и обсуждается протективная роль ГК в предотвращении его повреждения за счет снижения боли и нормализации паттернов движения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>osteoarthritis</kwd><kwd>hyaluronic acid</kwd><kwd>cross-link</kwd><kwd>total arthroplasty</kwd><kwd>contralateral joint</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>остеоартрит</kwd><kwd>гиалуроновая кислота</kwd><kwd>кросс-линк</kwd><kwd>тотальное эндопротезирование</kwd><kwd>контралатеральный сустав</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Long H, Liu Q, Yin H, et al.
