Using the institutional register of knee arthroplasty there were identified 37 orthopedic surgeons who perform more than 20 knee replacements annually. All of them agreed to participate in the survey. All surgeons were men with average age 43.1 years (min — 31, max — 64, moda — 41, SD = 8.9). The total number of knee arthroplasties performed by all respondents during the last year was 3094 . <bold><italic>Results. </italic></bold>The surgeons divided into two groups: 17 (46%) performed PKA but majority did not (20 (54%)). The average age of the surgeons of the 1st group was less than in the 2nd one (41.8 and 44.1 years (p&gt;0.05)). The surgeons from group 1 significantly often respond in a positive way regarding the advantages of PKA compared to TKA (p&lt;0.01). The significant differences among surgical estimations regarding PKA noted in the questions related to the speed of rehabilitation (p&lt;0.05), the achievement of the “forgotten knee” phenomenon (p&lt;0.01) and the frequency of postoperative complications (p&lt;0.01). There was a trend that the more often a surgeon utilized PKA, the more he believes in its advantages over TKA. Only 1 respondent consider PKA fully unreliable, and 6 surgeons reported that they are unfamiliar with surgical technique. Interestingly that all surgeons, except one in the second group, met right candidates for PKA in their daily practice. There was no correlation between the studied parameters and surgeons age, experience, as well as annual caseload. <bold><italic>Conclusions.</italic></bold> Every second surgeon (54%) who regularly performs knee replacement ignores PKA as a method of choice for selected patients with OA or ON despite evidence-based literature data even in a large orthopedic center. For PKA users among the most significant advantages of this approach there are the faster rehabilitation (p&lt;0.05), ability to reach the “forgotten knee” (p&lt;0.01), as well as lower incidence and severity of postoperative complications (p&lt;0.01).</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Введение.</italic></bold> Несмотря на доказанные преимущества частичной артропластики над тотальной у больных с поражением одного из отделов бедренно-большеберцового сочленения коленного сустава (КС), до сих пор в научном ортопедическом сообществе отсутствует единое мнение о целесообразности ее выполнения.<bold><italic> Цель исследования</italic></bold> — определить предпочтения отечественных ортопедов, регулярно выполняющих эндопротезирование коленного сустава, о целесообразности проведения его частичной артропластики. <bold><italic>Материал и методы.</italic></bold> На основании данных регистра артропластики НМИЦ ТО им. Р.Р. Вредена были определены 37 травматологов-ортопедов, выполняющих более 20 эндопротезирований коленного сустава (ЭП КС) в год, все из них согласились принять участие в опросе. Опрошенные хирурги были мужчинами, их средний возраст составил 43,1 года. Средний стаж ЭП КС опрашиваемых хирургов составлял от 5 до 7 лет. Для определения разницы в представлениях об одномыщелковом эндопротезировании (ОМЭП) среди практикующих ортопедов был разработан опросник, включающий 4 раздела, посвященных практическому опыту, пониманию показаний/противопоказаний к частичной артропластике, отношению к потенциальным преимуществам и недостаткам, а также причинам, ограничивающим использование данной технологии в своей клинической практике. <bold><italic>Результаты. </italic></bold>По результатам опроса хирурги были разделены на две группы: первая — выполняющие ОМЭП — 17 (46%) человек; вторая — не использующие ОМЭП — 20 (54%). Средний возраст хирургов 1-й группы — 41,8 лет, 2-й группы — 44,1 года. Хирурги 1-й группы чаще положительно отвечали по сравнению с хирургами 2-й группы о преимуществах ОМЭП по сравнению с тотальным ЭП КС (<italic>p</italic>&lt;0,01). Самые значимые различия были отмечены в вопросах, касающихся объема движений в суставе после ОМЭП (<italic>p </italic>= 0,05), достижения пациентами феномена «забытого колена» (<italic>p</italic>&lt;0,01) и частоты послеоперационных осложнений (<italic>p</italic>&lt;0,01). Чем чаще хирург использует ОМЭП в своей практике, тем в большей степени он считает, что она обладает преимуществами над тотальным ЭП КС. Не считал данную операцию надежной всего один респондент, а ее техникой не владели 6 респондентов. Корреляционных связей между изучаемыми параметрами и возрастом, опытом эндопротезирования, а также ежегодным количеством выполняемых артропластик КС выявлено не было. <bold><italic>Заключение. </italic></bold>Каждый второй ортопед (54%), регулярно выполняющий ЭП КС в крупном отечественном ортопедическом центре, игнорирует частичную артропластику как метод хирургического лечения больных гонартрозом и остеонекрозом, не считая данное оперативное лечение более рациональным, чем тотальная артропластика, несмотря на данные доказательной медицины. Специалисты, использующие ОМЭП в своей практике, наиболее существенными преимуществвами метода считают достаточный объем движений в суставе (<italic>p</italic> = 0,05), достижение феномена «забытого колена» (<italic>p</italic>&lt;0,01), а также меньшую частоту и тяжесть послеоперационных осложнений (<italic>p</italic>&lt;0,01).</p></trans-abstract><kwd-group xml:lang="en"><kwd>knee</kwd><kwd>osteoarthritis</kwd><kwd>partial arthroplasty</kwd><kwd>total arthroplasty</kwd><kwd>arthroplasty register</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>одномыщелковое эндопротезирование коленного сустава</kwd><kwd>эндопротезирование коленного сустава</kwd><kwd>тотальное эндопротезирование коленного суcтава</kwd><kwd>регистр артропластики</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Государственное бюджетное финансирование</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Корнилов Н.Н., Т.А.
