range of motion prior to total knee arthroplasty (TKA) is a key determinant of the postoperative range of motion. The chance that the accompanying stiffness of the extensor mechanism may lead to limited flexion following surgery increases with how restricted the preoperative range of motion was. It would make sense to enhance knee ROM before surgery in order to optimize flexion following TKA. Final flexion following TKA is affected by a number of factors, although preoperative range of motion is the most important.</p> <p><bold><italic>The aim of the study</italic></bold> — to evaluate the functional performance and efficacy of the preoperative exercise programme on the osteoarthritic knee during the exercise period, following arthroplasty, during immediate postoperative recovery, and at 1, 3, 6 and 12 months after surgery.</p> <p><bold><italic>Methods. </italic></bold>For the study, 156 patients with knee arthritis were collected over a period of one and a half years. In this prospective study, they were divided into a treatment group and a control group. Preoperative knee exercise was given to 78 patients for at least one month. Prior to and following the treatment group’s workouts, all patients were observed. The time in days before reaching 90° of knee flexion and the length of the hospital stay were the data that were gathered. At 4 weeks, 3 months, 6 months, and 1 year, each subject had their knee ROM and KSS reevaluated.</p> <p><bold><italic>Results. </italic></bold>Knee workouts were unquestionably helpful in achieving early knee flexion up to 90° in comparison to that of the control group. When the treatment group was compared to the control group, knee flexion to about 90° and more was attained in about 4 weeks; this difference was statistically significant (p&lt;0.01). However, there were no appreciable variations in the knee range of motion achieved on long-term follow-up for 6 months and a year.</p> <p><bold><italic>Conclusion. </italic></bold>In conclusion, prehabilitation significantly improves the KSS for the treatment group both before surgery and three months after surgery. Exercises done before to surgery help patients recover more quickly from TKA and may speed up the process of achieving a good flexion and extension range of motion. However there is no significant difference in functional outcome after one year post surgery in both groups.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Актуальность. </italic></bold>Объем движений в коленном суставе перед тотальным эндопротезированием является основополагающим фактором, влияющим на функциональные результаты после операции. Чем больше выражена контрактура на фоне ригидности мышц разгибателей до вмешательства, тем выше риск возникновения ограничений сгибания в послеоперационном периоде. В связи с этим представляется целесообразным увеличить предоперационный объем движений для оптимальной работы мышц-сгибателей после выполнения тотального эндопротезирования коленного сустава (ТЭКС). Сгибание в коленном суставе после тотального эндопротезирования зависит от множества факторов, среди которых самым важным является объем движений в предоперационном периоде.</p> <p><bold><italic>Цель исследования </italic></bold>— оценить функциональные показатели и эффективность предоперационной программы упражнений при остеоартрозе коленного сустава во время их выполнения, в период послеоперационного восстановления после эндопротезирования, а также через 1, 3, 6 и 12 мес. после операции.</p> <p><bold><italic>Материал и методы. </italic></bold>За полтора года в исследование были включены 156 пациентов, получивших хирургическое лечение по поводу артроза коленного сустава. Они были поделены на 2 проспективные группы — основную и контрольную. Семидесяти восьми пациентам в предоперационном периоде проводились физические упражнения на протяжении минимум одного месяца. Все пациенты основной группы были осмотрены до начала физической подготовки к оперативному лечению и после ее завершения. Тотальное эндопротезирование коленного сустава было выполнено всем 156 пациентам. Оценка объема движений в суставе производилась через 4 нед., 3, 6 и 12 мес. после оперативного вмешательства. Был определен срок, за который пациенты смогли достичь полного разгибания и сгибания до 90° в коленном суставе.</p> <p><bold><italic>Результаты. </italic></bold>Пациенты основной группы, выполнявшие физические упражнения в предоперационном периоде, смогли достичь сгибания в коленном суставе под углом 90° раньше (приблизительно 4 нед.), чем пациенты контрольной группы. Разница в сроках между сравниваемыми группами была статистически значимой (<italic>p</italic>&lt;0,01). Разница в объеме движений в коленном суставе между пациентами обеих групп, отмеченная во время осмотров через 6 и 12 мес. после операции, была незначительной.</p> <p><bold><italic>Заключение. </italic></bold>Предреабилитация значительно улучшила показатели по шкале KSS у пациентов группы исследования как в предоперационном периоде, так и через 3 мес. после операции. Упражнения, выполняемые перед оперативным вмешательством, позволяют сократить сроки восстановления пациентов после ТЭКС и способствуют более быстрому достижению хороших функциональных результатов. Однако через год после операции статистически значимых различий в амплитуде сгибания и разгибания в коленных суставах у пациентов обеих группах отмечено не было.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>osteoarthritis</kwd><kwd>prehabilitation exercise</kwd><kwd>functional outcome</kwd><kwd>TKA</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>остеоартроз коленного сустава</kwd><kwd>физические упражнения</kwd><kwd>функциональные результаты</kwd><kwd>тотальное эндопротезирование коленного сустава</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Calatayud J., Casaña J., Ezzatvar Y., Jakobsen M.D., Sundstrup E., Andersen L.L.
