Material and methods. The causes of 18 revision interventions after 142 consecutive UKA that have been performed in 137 patients since 2001 till 2012 were evaluated. The main reason for revision surgeries in these series was traumatic damage of different knee structures (7 cases): 3 - medial femur or tibia condyle fractures due to fall from height or collision, 1 - ACL rupture and one bearing dislocation both during mountain skiing injury, 1 - lateral menisci tear after rotational trauma, 1 - loose body formation caused by direct blow. All traumatic events took place during first five years after surgery. Other indications for revision were aseptic loosening of tibial component in 6 patients (after 4,8 years in average), disease progression in 2 (after 3 years in average), early infection in 1 and late hematogenous infection in 2 cases. In 16 patients revision TKA were performed with 10 cruciate-retaining, 5 posterior stabilized and 1 varus-valgus constrained implants. In 2 patients with lateral menisci tear and loose body arthroscopical intervention resolved the problem. Surprisingly in this cohort of patients acute trauma especially during sport activities shared the first place with aseptic loosening among the reasons for revision after UKA. This indirectly evidences that patients after UKA retained high level of physical activities and less restricted in sport that after TKA.</p></abstract><trans-abstract xml:lang="ru"><p>Цель - изучение структуры осложнений, развивающихся после одномыщелкового эндопротезирования коленного сустава и анализ их причин. Материал и методы. С 2001 по 2012 г. в РНИИТО им РР Вредена было выполнено 142 операции одномыщелкового эндопротезирования коленного сустава 137 пациентам. Изучены причины, приведшие к необходимости повторных хирургических вмешательств в 18 наблюдениях. Ведущей причиной повторных операций явились травмы - 7 больных, в том числе парапротезные переломы - 3, повреждение ПКС - 1, вывих вкладыша - 1, повреждение наружного мениска - 1 и внутрисуставное тело - 1. Асептическая нестабильность большеберцового компонента была выявлена у 6 больных, инфекционные осложнения - у 3, прогрессирование остеоартроза в смежных отделах сустава - у 2. В 16 наблюдений из 18 выполнена ревизионная артропластика коленного сустава и только у 2 пациентов удалось ограничиться артроскопическими операциями. При реэндопротезировании в 10 (62,5%) случаях были использованы имплантаты с сохранением ЗКС (задней крестообразной связки), в 5 (31,3%) - с замещением ЗКС и в 1 (6,2%) наблюдении - стабилизированный во фронтальной плоскости. Результаты. Частота и структура осложнений, приводящих к необходимости хирургических вмешательств после одномыщелкового эндопротезирования, существенно отличается от тотального замещения сустава. Данные 10-летнего наблюдения за этой категорией пациентов демонстрируют, что острая травма делит первое место с таким типичным осложнением любого эндопротезирования суставов, как асептическая нестабильность компонентов. Это свидетельствует о сохранении пациентами после частичной замены сустава высокого уровня двигательной активности и меньших ограничениях при занятиях спортом и физических нагрузках, чем после тотальной артропластики.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коленный сустав</kwd><kwd>одномыщелковое эндопротезирование</kwd><kwd>тотальное эндопротезирование</kwd><kwd>артропластика</kwd><kwd>ревизионное эндопротезирование</kwd><kwd>артроскопия</kwd><kwd>knee</kwd><kwd>unicompartmental knee arthroplasty (UKA)</kwd><kwd>total knee arthroplasty (TKA)</kwd><kwd>revision knee arthroplasty</kwd><kwd>knee arthroscopy</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ageberg E., Engstrom G., Gerhardsson de Verdier M., Rollof J., Roos E.M., Lohmander L.S.
