However, the method of preparation of bone marrow aspirate concentrate determines both the cellular composition and treatment outcomes.</p> <p><bold>AIM:</bold><italic> </italic>This study aimed to assess the efficacy and safety of a novel method for obtaining bone marrow aspirate concentrate for the treatment of early-stage avascular necrosis of the femoral head (ANFH).</p> <p><bold>METHODS:</bold><italic> </italic>The study included 35 patients (64 hip joints) with ARCO stage II–IIIA ANFH. Treatment at the N.N. Priorov National Medical Research Center of Traumatology and Orthopedics involved core decompression combined with administration of bone marrow aspirate concentrate obtained using an original method. The follow-up period was 12 months. Functional outcomes (HHS, WOMAC), pain (VAS), quality of life (SF-36), and ANFH stage and activity (MRI of both joints ≥1.5 T before and 3, 6, and 12 months after treatment; CT before and 6 and 12 months after treatment) were assessed.</p> <p><bold>RESULTS:</bold><italic> </italic>The proposed method significantly increased cell yield in the bone marrow aspirate concentrate after centrifugation compared to native bone marrow. Following treatment, HHS and WOMAC scores improved significantly, as did pain intensity according to VAS. Progression from stage II to IIIA by ARCO was observed in 4 hips (4 patients), and from stage IIIA to IIIB by ARCO in 5 hips (4 patients). After 12 months, the necrotic lesion size remained stable in all joints. Total hip arthroplasty was required in 4 patients (5 hips; 7.7% of all joints).</p> <p><bold>CONCLUSION:</bold><bold> </bold>The proposed method for obtaining bone marrow aspirate concentrate enables the injection of the desired amount of cells into the femoral head, restoring normal cellular composition. The efficacy of bone marrow aspirate concentrate has been demonstrated in early-stage avascular necrosis of the femoral head (ARCO stage II), which was observed in the majority of patients in our cohort.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Применение концентрата аспирата костного мозга при асептическом некрозе костей позволяет улучшить результаты лечения пациентов, а также отсрочить или избежать эндопротезирования суставов. Однако клеточный состав концентрата костного мозга и результаты лечения зависят от методики его получения, что в конечном счёте влияет на исход лечения.</p> <p><bold>Цель.</bold> Оценить эффективность и безопасность нового способа получения концентрата аспирата костного мозга для лечения пациентов с ранними стадиями асептического некроза головки бедренной кости (АНГБК).</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> В исследование включены 35 пациентов (64 тазобедренных сустава) с АНГБК II–IIIA стадии по ARCO. Лечение в ФГБУ «НМИЦ ТО им. Н.Н. Приорова» включало туннелизацию с применением концентрата аспирата костного мозга, полученного по оригинальной методике. Период наблюдения — 12 месяцев. Оценивали функциональные результаты (HHS, WOMAC), боль (ВАШ), качество жизни (SF-36), стадию и активность АНГБК (МРТ обоих суставов ≥1,5 Тл до операции и через 3, 6, 12 месяцев после лечения; КТ до операции и через 6, 12 месяцев после лечения).</p> <p><bold>Результаты.</bold><bold> </bold>Представленная методика обеспечила значительное увеличение количества клеток в концентрате костного мозга после центрифугирования по сравнению с нативным костным мозгом. Отмечено значимое улучшение показателей HHS и WOMAC, снижение боли по ВАШ после лечения. Прогрессирование со II до IIIA стадии по ARCO наблюдалось в 4 тазобедренных суставах (4 пациента), с IIIA до IIIB стадии по ARCO — в 5 тазобедренных суставах (4 пациента). Размер некротического очага остался неизменным через 12 месяцев во всех суставах. Тотальное эндопротезирование потребовалось 4 пациентам (5 суставов; 7,7% от общего числа суставов).</p> <p><bold>Заключение.</bold> Представленная методика получения концентрата аспирата костного мозга позволяет достичь целевого количества клеток, которое необходимо ввести в головку бедренной кости, чтобы восстановить то же количество клеток, что и в нормальной головке бедренной кости. Эффективность использования концентрата аспирата костного мозга доказана при ранней стадии асептического некроза головки бедренной кости (II стадия по ARCO), которую имели большинство наблюдаемых нами пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>avascular necrosis</kwd><kwd>aseptic necrosis</kwd><kwd>osteonecrosis</kwd><kwd>bone marrow aspirate concentrate</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>асептический некроз костей</kwd><kwd>аваскулярный некроз</kwd><kwd>остеонекроз</kwd><kwd>концентрат аспирата костного мозга</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mont MA, Cherian JJ, Sierra RJ, Jones LC, Lieberman JR.
