The article reports the results of 65 endoprosthesis reconstruction of the knee joint in children and adolescents with oncological pathology for a 5-year period (2012-2017). The study was approved by the Independent Ethics Committee of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology, and Immunology. Evaluation of functional results was performed using the MSTS scale 3 months after the operation. Postoperative complications were analyzed according to the Henderson classification. The average indicator of the functional rate after operative treatment, according to the MSTS scale, was 76%. The most common postoperative complications were structural failures (7.6%) and infectious complications (6.2%). Overall survival in the largest group of patients with osteosarcoma (56 patients) was 82 ± 12%, event-free survival 37 ± 12%. The use of individual expandable endoprostheses makes it possible to perform operations for patients with skeletal immaturity. Endoprosthesis replacement provide good oncological and functional results, and also contribute to the most adequate social adaptation of the child.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен анализ собственного опыта удаления опухолей и последующего эндопротезирования у пациентов детского и подросткового возраста с первичными опухолями костей. Данное исследование поддержано Независимым этическим комитетом и утверждено решением Ученого совета НМИЦ ДГОИ. За 5-летний период (2012-2017) выполнены 65 эндопротезирований коленного сустава у детей и подростков с онкологической патологией. Оценку функциональных результатов проводили с помощью шкалы MSTS через 3 месяца с момента операции. Послеоперационные осложнения анализировали согласно классификации по Henderson. Средний показатель функционального результата после оперативного лечения по шкале MSTS составил 76%. Чаще среди послеоперационных осложнений отмечены структурные повреждения (7,6%) и инфекционные осложнения (6,2%). Общая выживаемость в наиболее многочисленной группе пациентов с остеосаркомой (56 человек) составила 82 ± 12%; бессобытийная выживаемость - 37 ± 12%. Использование индивидуальных раздвижных эндопротезов позволяет проводить операции пациентам детского возраста - с незрелым скелетом. Эндопротезирование обеспечивает хорошие онкологические и функциональные результаты, способствует наибольшей социальной адаптации ребенка.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bone sarcomas</kwd><kwd>bone tumors in children</kwd><kwd>limb-sparing surgery</kwd><kwd>endoprosthesis replacement</kwd><kwd>expandable endoprosthesis</kwd><kwd>modular oncological endoprosthesis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркомы костей</kwd><kwd>опухоли костей у детей</kwd><kwd>органосохраняющие операции</kwd><kwd>эндопротезирование</kwd><kwd>раздвижной онкологический эндопротез</kwd><kwd>модульный онкологический эндопротез</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Амджен, компани; Подари жизнь, благотворительный фонд</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
