Many<bold> </bold>patients who visit orthopedic surgeons mainly complained of knee pain, which is often diagnosed as osteoarthritis affecting the medial compartment, whereas the lateral compartment and patello-femoral joint remain relatively unaffected.</p> <p><bold>AIM</bold><bold>:</bold> This study aimed to establish criteria for patient selection and validate an evidence-based approach for selecting candidates for unicompartmental knee arthroplasty (UKA). Key considerations in patient selection for UKA include identifying the presence of bone-on-bone osteoarthritis in the medial compartment, ensuring a functionally normal anterior cruciate ligament, maintaining full-thickness cartilage in the lateral compartment, verifying a functionally normal medial collateral ligament, and confirming the absence of severe damage lateral to the patello-femoral joint.</p> <p><bold>MATERIALS</bold><bold> </bold><bold>AND</bold><bold> </bold><bold>METHODS</bold><bold>: </bold>From a consecutive cohort of 390 patients with medial knee pain, preoperative radiographs of bilateral knee including anteroposterior/lateral/Rosenberg/20° valgus stress views were collected, and results were tabulated. Patients were categorized into appropriate groups. The suitability for UKA was determined based on the Oxford radiological decision aid, history, examination, and radiographic assessment including stress radiographs.</p> <p><bold>RESULTS</bold><bold>: </bold>The Oxford radiological decision aid demonstrated 92% sensitivity and 88% specificity. According to the radiographic assessment, 49% of the knees were considered suitable for Oxford UKA (OUKA), whereas 51% were deemed unsuitable. Among the 51 knees identified as unsuitable for OUKA, 40% did not meet one radiographic criterion, 38% did not meet two criteria, 22% did not meet three criteria, and &lt;1% did not meet four criteria.</p> <p><bold>CONCLUSION</bold><bold>: </bold>The Oxford radiographic decision aid safely and reliably identifies the appropriate patients for meniscal-bearing UKA and achieves good results in this population. The widespread use of this radiological decision aid should improve the results of UKA.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><bold> </bold>Значительное число пациентов обращаются к хирургам-ортопедам с жалобами на боль в колене, которая часто диагностируется как остеоартрит, поражающий медиальный отдел, в то время как латеральный отдел и надколенно-бедренный сустав остаются относительно незатронутыми.</p> <p><bold>Цель.</bold> Установление критериев отбора пациентов и проверка научно обоснованного подхода к отбору кандидатов на одномыщелковое протезирование коленного сустава. Ключевыми моментами при отборе пациентов для одномыщелкового протезирования коленного сустава являются выявление остеоартроза кость в кость в медиальном отсеке, обеспечение функционально нормальной передней крестообразной связки, сохранение полной толщины хряща в латеральном отсеке, проверка функционально нормальной медиальной коллатеральной связки и подтверждение отсутствия серьёзного повреждения пателлофеморального сустава в латеральном направлении.</p> <p><bold>Материалы и методы.</bold> У 390 пациентов с болью в медиальной части коленного сустава были собраны предоперационные рентгенограммы коленных суставов, включая AP/LAT/Rosenberg view/20° valgus stress view, и результаты были сведены в таблицу. Пациенты были распределены по соответствующим группам. Отбор кандидатов на одномыщелковое протезирование коленного сустава определялся с помощью Оксфордской рентгенологической системы принятия решений, анамнеза, осмотра, рентгенографической оценки, включая стресс-рентгенограммы.</p> <p><bold>Результаты.</bold> Оксфордская рентгенологическая система принятия решений продемонстрировала чувствительность 92% и специфичность 88%. По результатам рентгенографической оценки 49% коленных суставов были признаны пригодными для проведения одномыщелкового протезирования коленного сустава, а 51% — непригодными. Среди 51 коленного сустава, признанных непригодными, 40% не соответствовали одному рентгенографическому критерию, 38% не соответствовали двум критериям, 22% — трём и менее 1% — четырём критериям.</p> <p><bold>Заключение.</bold> Оксфордская рентгенологическая система принятия решений безопасно и надёжно определяет подходящих пациентов для проведения одномыщелкового протезирования коленного сустава с менисковой опорой и позволяет достичь хороших результатов в данной популяции. Широкое использование этого рентгенологического пособия по принятию решений должно улучшить результаты одномыщелкового протезирования коленного сустава.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Oxford radiological decision aid</kwd><kwd>unicompartmental knee arthroplasty</kwd><kwd>osteoarthritis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Оксфордская рентгенологическая система принятия решений</kwd><kwd>односуставная артропластика коленного сустава</kwd><kwd>остеоартрит</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Hsu H, Siwiec RM.
