Post-traumatic pain is considered as one of the predictors of the development of post-traumatic osteoarthritis (PTOA). Early changes in the knee joint, characteristic of the development of PTOA, can be determined using magnetic resonance imaging (MRI).</p> <p><bold>Aim </bold>– to evaluate the relationship between CPTР and structural changes in the knee joint, which are determined using MRI.</p> <p><bold>Material and methods. </bold>The study group consisted of 98 patients, 48% women and 52% men, aged 39.2 ± 14.7 years, who had suffered a knee joint injury with damage to the anterior cruciate ligament (ACL) and/or meniscus (confirmed by MRI data), and experiencing pain ≥4 points on a numerical rating scale (CRS) of at least one month after the injury. The patients were followed up for 12 months. CPTР was determined with pain persistence for at least 3 months at the level of 4 points on the CRS. Repeated MRI was performed 12 months after inclusion in the study. Changes in the knee joint according to the MRI data were quantified using the WORMS system.</p> <p><bold>Results.</bold> CPTР was detected in 45.9% of patients. According to the initial MRI parameters, the groups of patients with CPTР (n=45) and without CPTP (n=53) significantly differed in cartilage morphology (minimal changes were more often detected in patients without CPTР), the presence of osteophytes, damage to the medial collateral ligament and rupture of the medial meniscus body. Almost all patients in both groups had ligament damage and meniscus rupture (with varying degrees of severity), as well as synovitis; about a third of the examined individuals had signs of bone marrow edema. After 12 months observations between patients with and without CPTР showed a significant difference in MRI parameters such as cartilage morphology, osteophytes of the medial condyle of the femur, damage to the posterior cruciate and medial collateral ligaments, rupture of the body, anterior and posterior horns of the medial meniscus, rupture of the anterior horn of the lateral meniscus, synovitis. Thus, severe cartilage damage (≥2 by WORMS) was noted in 82.1% of patients with CPTР and 43.4% without CPTР (p &lt;0.05), synovitis in 95.6% and 24.5% (p &lt;0.05).</p> <p><bold>Conclusion. </bold>CPTР, which occurs after the knee joint injury, is associated with structural changes in the joint, which can be regarded as an early stage of PTOA.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Хроническая посттравматическая боль (ХПТБ) возникает у 15–50% пациентов, перенесших травму коленного сустава (КС). ХПТБ рассматривается как один из предикторов развития посттравматического остеоартрита (ПТОА). Ранние изменения КС, характерные для развития ПТОА, могут определяться с помощью магнитно-резонансной томографии (МРТ).</p> <p><bold>Цель</bold> – oценить взаимосвязь между ХПТБ и структурными изменениями КС, которые определяются с помощью МРТ.</p> <p><bold>Материал и методы. </bold>Исследуемую группу составили 98 пациентов, 48% женщин и 52% мужчин, возраст 39,2 ± 14,7 года, перенесших травму КС с повреждением передней крестообразной связки (ПКС) и/или мениска (подтвержденное данными МРТ) и испытывающих боль ≥4 балов по числовой рейтинговой шкале (ЧРШ) не менее месяца после травмы. Пациенты наблюдались в течение 12 мес. ХПТБ определялась при персистенции боли не менее 3 мес. на уровне ≥4 балов по ЧРШ. Повторная МРТ проводилась через 12 мес. после включения в исследование. Изменения КС по данным МРТ оценивались количественно по системе WORMS.</p> <p><bold>Результаты.</bold> ХПТБ была определена у 45,9% пациентов. По исходным<bold> </bold>параметрам МРТ группы пациентов с ХПТБ (n=45) и без ХПТБ (n=53) достоверно различались по морфологии хряща (минимальные изменения чаще выявлялись у пациентов без ХПТБ), наличию остеофитов, повреждению медиальной коллатеральной связки и разрыву тела медиального мениска. Практически у всех пациентов в обеих группах отмечались повреждение связок и разрыв мениска (с разной степенью выраженности), а также синовит; около трети обследованных лиц имели признаки отека костного мозга. Через 12 мес. наблюдения между пациентами с ХПТБ и без нее была зафиксирована достоверная разница по таким МРТ-параметрам, как морфология хряща, остеофиты медиального мыщелка бедренной кости, повреждение задней крестообразной и медиальной коллатеральной связок, разрыв тела, переднего и заднего рога медиального мениска, разрыв переднего рога латерального мениска, синовит. Так, выраженное повреждение хряща (≥2 по WORMS) было отмечено у 82,1% пациентов с ХПТБ и у 43,4% без ХПТБ (р &lt;0,05), синовит у 95,6% и 24,5% (р &lt;0,05).</p> <p><bold>Заключение:</bold> ХПТБ, возникающая после травмы КС, ассоциирована со структурными изменениями сустава, которые можно расценивать как раннюю стадию ПТОА.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic post-traumatic pain</kwd><kwd>post-traumatic osteoarthritis</kwd><kwd>magnetic resonance imaging</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хроническая посттравматическая боль</kwd><kwd>посттравматический остеоартрит</kwd><kwd>магнитно-резонансная томография</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out using budgetary funding for the implementation of the state assignment on topic FURS-2022-0009 (state assignment number 1021062512064-0).</funding-statement><funding-statement xml:lang="ru">Работа выполнена за счет средств бюджетного финансирования на выполнение государственного задания по теме FURS-2022-0009 (номер государственного задания 1021062512064-0).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zubavlenko RA, Ulyanov VYu, Belova SV.
