Сравнить частоту эндопротезирования коленного сустава у больных, получавших стандартное лечение нестероидными противовоспалительными препаратами (НПВП) в комбинации с симптоматическими лекарственными средствами замедленного действия (SYSADOA, symptomatic slow acting drugs for osteoarthritis) либо их сочетание с низкодозной лучевой терапией (НДЛТ), при остеоартрите коленных суставов 0–2-й стадий.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Представлены отдалённые результаты рандомизированного контролируемого испытания в выборке из 292 пациентов с подтверждённым остеоартритом (ОА) коленных суставов по критериям Altmаn (1991), рентгенологической стадией 0–2 по Kellgren – Lawrence, случайным образом распределённых в две группы. Контрольная группа (n = 146) получала терапию комбинацией НПВП и SYSADOA. В группе исследования (n = 146) пациенты дополнительно к стандартному лечению получали НДЛТ до суммарной дозы 4,5 Гр. Кумулятивный риск эндопротезирования оценивали с помощью актуарного анализа и метода Каплана – Майера. Для оценки профилактического потенциала НДЛТ рассчитывали предотвратимые доли для выборки (AF, attributable fraction) и для генеральной совокупности (PAF, population attributable fraction).</p></sec><sec><title>Результаты</title><p>Результаты. Общее время наблюдения составило 2131,2  человеко-лет. 4,1 % (n = 6) пациентам группы исследования проведено эндопротезирование против 7,5 % (n = 11) в контрольной группе. Отношение плотностей инцидентности составило 0,60 (95% ДИ: 0,18–1,88), что соответствует снижению риска на 67 %, но результаты не достигали уровня статистической значимости по причине малого числа эндопротезирований (p = 0,340). Предотвратимая доля эндопротезирований составила 40 % для выборочной совокупности и 21 % для генеральной совокупности пациентов с рентгенологической стадией 0–2.</p></sec><sec><title>Заключение</title><p>Заключение. Применение НДЛТ снижает риск эндопротезирования на две трети и потенциально способно снизить частоту эндопротезирования на 21 % у больных ОА коленного сустава. Требуется исследование на большей выборке.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim. To compare the incidence of knee arthroplasty in patients receiving standard treatment with non-steroidal anti-inflammatory drugs (NSAIDs) in combination with symptomatic slow acting drugs for osteoarthritis (SYSADOA), or combination of NSAIDs and SYSADOA with low-dose radiation therapy (LDRT) in patients with stage 0–2 knee osteoarthritis (OA). </p></sec><sec><title>Materials and methods</title><p>Materials and methods. The article presents the results of randomized controlled study of 292 patients with confirmed knee OA according to Altman’s criteria (1991) and Kellgren – Lawrence radiographic stages 0–2 who were randomized into two groups. The control group (n = 146) received standard therapy of NSAIDs + SYSADOA. Patients of the study group (n  =  146) received combination of standard therapy and  LDRT up to a total dose of 4.5  Gy. The  cumulative risk of knee arthroplasty was assessed using actuarial analysis and the Kaplan – Meier method. Attributable (AF) and population attributable (PAF) fractions were calculated to assess LDRT preventive potential. </p></sec><sec><title>Results</title><p>Results. The total observation period was 2131.2 person-years. Knee arthroplasty was performed in 4.1 % (n = 6) of patients in the study group against 7.5 % (n = 11) in the control group. The  incidence density ratio was 0.60 (95%  CI: 0.18–1.88), which corresponds to a risk reduction by 67 %, but the differences were not statistically significant due to the small number of cases (p = 0.340). The AF was 40 % while the PAF was 21 %. </p></sec><sec><title>Conclusions</title><p>Conclusions. The use of LDRT reduces the risk of knee arthroplasty by two-thirds and has the potential to prevent 21 % cases of knee arthroplasty in patients with knee OA. A study on a larger sample is required.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>остеоартрит</kwd><kwd>коленный сустав</kwd><kwd>эндопротезирование</kwd><kwd>низкодозная лучевая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteoarthritis</kwd><kwd>knee joint</kwd><kwd>joint arthroplasty</kwd><kwd>low-dose radiation therapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cui A, Li H, Wang D, Zhong J, Chen Y, Lu H.
