Вопросы тактики ведения пациентов с пателлофеоморальным артрозом в настоящий момент остаются открытыми, и хирургическое лечение активно обсуждается в литературе. Принято, что при наличии полнослойного дефекта хряща, изменений субхондральной кости выставляются показания для эндопротезирования коленного сустава. Но, в настоящий момент, не всегда эндопротезирование коленного сустава отвечает всем запросам пациента относительно физической активности, особенно у молодых пациентов. Решение данной проблемы потенциально позволит улучшить качество жизни молодых пациентов с изолированным артрозом пателлофеморального сочленения.Цель исследования: оценить красткосрочный результат лечения пациента с пателлофеморальным артрозом после артроскопической краевой моделирующей резекции надколенника и рефиксации комплекса сухожилия медиальной головки четырёхглавой мышцы бедра.Материалы и методы. Пациент 41 года, обратился на консультацию по поводу ограничения движений и выраженного болевого синдрома в области коленного сустава. В анамнезе неоднократные вывихи надколенника, два хирургических вмешательства по его стабилизации.Результаты. Через год на контрольном приеме у пациента отсутствуют жалобы на боли и ограничение движений в коленном суставе.Обсуждение. На сегодняшний день тактика ведения молодых пациентов с пателлофеморальным артрозом остается открытым вопросом. Результаты и эффективность органосохраняющих операций широко не изучены и требуют научной оценки на большем количестве пациентов.Заключение. При помощи артроскопической краевой моделирующей резекции надколенника и транспозиции сухожилия медиальной головки четырехглавой мышцы можно достичь удовлетворительных функциональных результатов в ситуации с пателлофеморальным артрозом выраженной стадии по классификации Outerbridge.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. The management strategies for patients with patellofemoral osteoarthritis remain controversial, with surgical treatment options being actively debated in current literature. Current guidelines indicate knee arthroplasty for cases with full-thickness cartilage defects and subchondral bone changes. However, at present, knee arthroplasty does not always meet all the patient's demands regarding physical activity, especially in young patients. Addressing this issue could potentially improve quality of life for young patients with isolated patellofemoral joint osteoarthritis.The purpose to evaluate short-term outcomes in a patient with patellofemoral osteoarthritis following arthroscopic marginal contouring resection of the patella with refixation of the medial quadriceps tendon complex.Materials and methods. A 41-year-old male patient presented with limited range of motion and severe knee pain. Medical history included recurrent patellar dislocations and two previous patellar stabilization procedures.Results. At one-year follow-up, the patient reported complete resolution of pain and full restoration of knee mobility.Discussion. The optimal management of young patients with patellofemoral osteoarthritis remains unresolved. The efficacy of joint-preserving surgical techniques requires further scientific evaluation with larger patient cohorts.Conclusion. Arthroscopic marginal contouring resection of the patella combined with medial quadriceps tendon realignment can yield satisfactory functional outcomes in advanced-stage patellofemoral osteoarthritis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пателлофеморальный артроз</kwd><kwd>нестабильность надколенника</kwd><kwd>артроскопия</kwd><kwd>хондральная резекция</kwd><kwd>четырехглавая мышца бедра</kwd><kwd>коленный сустав</kwd><kwd>молодой пациент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>patellofemoral osteoarthritis</kwd><kwd>patellar instability</kwd><kwd>arthroscopy</kwd><kwd>chondroplasty</kwd><kwd>quadriceps muscle</kwd><kwd>knee joint</kwd><kwd>young patient</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">Gaitonde DY, Ericksen A, Robbins RC.
