X-ray can be used to diagnose knee osteoarthritis. Total knee arthroplasty of the two knees can be done simultaneously or staged in two different sessions.</p> <p><bold>AIM:</bold><italic> </italic>To assess simultaneous bilateral total knee arthroplasty based on complications and patient satisfaction and compare the results to those in the literature to provide a clear guideline for appropriate choice for patients.</p> <p><bold>MATERIALS AND METHODS:</bold><italic> </italic>A prospective cohort study was conducted in Ain Shams University Hospital in Cairo and Taiba Hospital in Kuwait on 45 cases who suffered from advanced bilateral knee osteoarthritis and underwent simultaneous bilateral total knee arthroplasty between August 2018 and October 2020.</p> <p><bold>RESULTS:</bold><italic> </italic>The study was conducted on 45 patients aged 47–75 years (mean age: 64.29±6.23 years). There were 41 females (91.1%) and 4 males (8.9%). Pre- and postoperative patient satisfaction was 15.24±2.45 and 32.18±4.08, respectively, with a mean difference of 16.93. Moreover, the pre- and postoperative objective knee score and Knee Society Scoring System, were 58.90±6.28 and 82.62±5.70, respectively. Additionally, the pre- and postoperative functional knee score were 51.39±8.67 and 73.80±7.75, respectively. Four patients (8.9%) had complications: 3 (6.7%) had superficial infection and 1 (2.2%) had acute coronary syndrome.</p> <p><bold>CONCLUSION:</bold><italic> </italic>Simultaneous bilateral total knee arthroplasty can be safe and have low mortality and complication rates with careful preoperative patient selection.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><bold> </bold>Прогрессирующий остеоартроз коленного сустава — распространённая клиническая проблема, требующая проведения артропластики коленного сустава. Для диагностики остеоартроза коленного сустава можно использовать рентгенографию. Тотальная артропластика двух коленных суставов может быть выполнена одновременно или поэтапно, в два разных этапа.</p> <p><bold>Цель.</bold><bold> </bold>Оценить одновременную двустороннюю тотальную артропластику коленного сустава с точки зрения осложнений и удовлетворённости пациентов и сравнить полученные результаты с данными литературы, чтобы предоставить пациентам чёткое руководство по выбору.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> Было проведено проспективное когортное исследование в университетской больнице Ain Shams в Каире и больнице Taiba в Кувейте с участием 45 пациентов с прогрессирующим двусторонним остеоартрозом коленного сустава, которым в период с августа 2018 по октябрь 2020 года была проведена одновременная двусторонняя тотальная артропластика коленного сустава.</p> <p><bold>Результаты.</bold><bold> </bold>В исследовании приняли участие 45 пациентов в возрасте 47–75 лет (средний возраст — 64,29±6,23 года). Среди них были 41 женщина (91,1%) и 4 мужчины (8,9%). Удовлетворённость пациентов до и после операции составила 15,24±2,45 и 32,18±4,08 соответственно со средней разницей в 16,93. Кроме того, до и после операции объективный показатель коленного сустава и балл по Knee Society Scoring System составили 58,90±6,28 и 82,62±5,70 соответственно. При этом функциональная оценка коленного сустава до и после операции составила 51,39±8,67 и 73,80±7,75 соответственно. У четырёх пациентов (8,9%) возникли осложнения: у троих (6,7%) — поверхностная инфекция и у одного (2,2%) — острый коронарный синдром.</p> <p><bold>Заключение.</bold><bold> </bold>Одновременная двусторонняя тотальная артропластика коленного сустава может быть безопасной и иметь низкие показатели смертности и осложнений при тщательном предоперационном отборе пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>simultaneous bilateral total knee arthroplasty</kwd><kwd>patient satisfaction</kwd><kwd>complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>одновременная двусторонняя тотальная артропластика коленного сустава</kwd><kwd>удовлетворённость пациентов</kwd><kwd>осложнения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Altman RD, Gold GE.
