The x-ray scale developed by Wall and colleagues is a commonly used evaluation tool for OCD lesion assessment. This tool has excellent reliability but is associated with radiologic exposure. Also, it provides complete information about bone structure only, even though the articular cartilage is also involved in the pathological process. Lack of cartilage assessment combined with radiation exposure facilitated the development of the novel MRI-based OCD healing assessment tool. It could draw attention to bone and cartilage during healing assessment to improve decision-making in the postoperative period after OCD treatment.</p> <p><bold><italic>AIM</italic></bold><italic>:</italic> This study assesses the reliability of a developed novel MRI-based OCD healing assessment tool.</p> <p><bold><italic>MATERIALS AND METHODS</italic></bold><italic>:</italic> Ten patients with OCD of the femoral condyle were involved in the current study. A reliability test for the novel MRI-based assessment tool was performed with the expert group comprising six participants to assess 34 MRI studies of 10 patients. From all studies, one study was obligatory for each patient before the operative treatment, and a postoperative MRI study series was performed during the first postoperative year. Each MRI study was examined by each expert twice with a 4-week time lag. The novel MRI-based assessment tool consists of five criteria, of which the common criterion was “general healing,” incorporating all previously described ones. Each criterion was tested, and a two-way mixed-effects intraclass correlation coefficient (ICC) was used to assess intraobserver and interobserver reliability.</p> <p><bold><italic>RESULTS</italic></bold><italic>:</italic> The main parameter “general healing” calculations were made first. Two patients achieved full OCD lesion healing with 100 scale points and two patients with 97.5 and 98.5 points, respectively. Other patients reached the cut-off value of 75 points and were defined as “healed with minimally detectable changes on MRI.” Second, a two-way mixed-effects ICC calculation was performed. The “bone marrow extension” parameter reached the value of 0.972, “the extent of the union” – 0.984, “bone structure” – 0.977, and “articular cartilage intensity and structure” – 0.977. The general healing parameter reached the value of 0.993. These values corresponded to the excellent marks according to the guidelines for ICC assessment. The novel MRI-based assessment tool showed excellent intraobserver and interobserver reliability.</p> <p><bold><italic>CONCLUSIONS</italic></bold><italic>:</italic> The novel MRI-based assessment tool permits assessing bony and cartilage structures while making decisions about OCD lesion healing in the postoperative period. The novel OCD healing assessment tool has excellent intraobserver and interobserver reliability. Also, it is recommended for use in clinical and research practice since a study revealed a correlation of the MRI healing score with that of the clinical assessment tool.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование</italic></bold><italic>.</italic> Для оценки восстановления костной ткани в очаге рассекающего остеохондрита традиционно используют рентгенологическую шкалу. Несмотря на широкое применение, в этой шкале не учитывается восстановление суставного хряща. В связи с потребностью в надежном и универсальном инструменте оценки заживления очагов рассекающего остеохондрита была разработана новая шкала, основанная на анализе магнитно-резонансных томограмм коленного сустава, отражающая состояние суставного хряща и субхондральной кости, а также общее заживление очага рассекающего остеохондрита.</p> <p><bold><italic>Цель</italic></bold> — определение надежности методики оценки заживления патологического очага рассекающего остеохондрита по результатам магнитно-резонансной томографии.</p> <p><bold><italic>Материалы и методы</italic></bold><italic>.</italic> Изучены результаты 34 исследований, проведенных путем выполнения магнитно-резонансной томографии 10 детям с рассекающим остеохондритом мыщелка бедренной кости в ДГКБ им. Н.Ф. Филатова в течение года наблюдения. Всем детям, кроме одного, проводили трансхондральные остеоперфорации с внутрисуставным введением плазмы, обогащенной тромбоцитами. Результаты магнитно-резонансной томографии анализировала экспертная группа из 6 человек разного уровня профессиональной подготовки по пяти параметрам шкалы — каждый эксперт дважды с интервалом в 4 нед. Для подтверждения гипотезы о надежности новой методики использовали коэффициент внутриклассовой корреляции (ICC). С целью повышения достоверности результатов ICC отдельно рассчитывали для подгрупп, в которых выполняли магнитно-резонансную томографию в раннем (2–6 мес. с момента операции) и позднем (9–12 мес.) послеоперационных периодах.</p> <p><bold><italic>Результаты</italic></bold><italic>.</italic> Величина ICC для показателя «степень отека костного вещества» составила 0,972, «степень консолидации» — 0,984, «структура костного вещества» — 0,977, «структура суставного хряща» — 0,977, «общее заживление очага» — 0,993. Анализ магнитно-резонансных томограмм в подгруппах раннего и позднего послеоперационных периодов подтвердил высокую степень надежности новой методики. При оценке согласованности данных каждого исследователя, полученных с интервалом в 4 нед., значение ICC по всей выборке составило 0,86, значение ICC в раннем послеоперационном периоде — 0,81, в позднем послеоперационном периоде — 0,92 (<italic>p</italic> &lt; 0,05).</p> <p><bold><italic>Заключение</italic></bold><italic>.</italic> Разработанная шкала оценки заживления очагов рассекающего остеохондрита по магнитно-резонансной томографии обладает высокой степенью воспроизводимости и надежности, но для широкого клинического применения необходима ее валидация на большой выборке пациентов с рассекающим остеохондритом.</p></trans-abstract><trans-abstract xml:lang="zh"><p><italic><bold>论证。</bold></italic>为了评估剥脱性骨软骨炎病灶内骨组织的恢复情况，传统上采用X线评分法。虽然被广泛使用，但这个量表并没有考虑到关节软骨的再生。由于需要一种可靠和通用的工具来评估剥脱性骨软骨炎病灶的愈合，一种新的量表被开发出来。该新的量表是基于对膝关节磁共振成像的分析，反映了关节软骨和软骨下骨的状态，以及剥脱性骨软骨炎病灶的总体愈合情况。</p> <p>本研究的<italic><bold>目的</bold></italic>是根据磁共振成像的结果，确定评估剥脱性骨软骨炎病理病灶愈合的方法的可靠性。</p> <p><italic><bold>材料与方法。</bold></italic>研究了 Children’s Municipal Clinical Hospital named after N.F.
