Modern literature presents conflicting data regarding the influence of the posterior tibial slope on the risk of traumatic ACL graft rupture.</p> <p><bold><italic>Aim</italic></bold> <bold><italic>of</italic></bold> <bold><italic>the</italic></bold> <bold><italic>study</italic></bold> — to determine if there is a correlation between the posterior tibial slope and ACL graft injury in patients who have previously undergone ACL reconstruction.</p> <p><bold><italic>Methods</italic></bold><bold><italic>. </italic></bold>This was a single-center cohort retrospective study that included patients diagnosed with a complete ACL rupture and who had undergone ACL reconstruction using standard techniques without graft rupture at the last follow-up. Inclusion criteria for the first group included a diagnosis of traumatic ACL rupture followed by reconstruction, a graft composed of semitendinosus and gracilis tendons (St+Gr), femoral fixation with a cortical button, tibial fixation with a sleeve and screw, and the absence of graft rupture at the time of the study. This group included 30 consecutive patients (15 males and 15 females) with a mean age of 36.3 years (min 17, max 59). Inclusion criteria for the second group included an indirect traumatic mechanism of ACL graft rupture and subsequent revision ACL reconstruction. This group consisted of 33 patients (23 males and 10 females) with a mean age of 33.0 years (min 19, max 60). The lateral (LPTS) and medial (MPTS) posterior tibial slopes were measured on lateral knee radiographs.</p> <p><bold><italic>Results</italic></bold><bold><italic>. </italic></bold>The median time from surgery to the last follow-up in the first group was 65 months (IQR 60; 66), while in the second group, it was 48 months (IQR 9; 84). The median MPTS in the first group was 7.8° (IQR 5.3; 9.4), while in the second group, it was 8.5° (IQR 7.5; 11). The median LPTS in the first group was 9.9° (IQR 8.4; 12.1), whereas in the second group, it was 12.0° (IQR 9; 15.4). There was no statistically significant difference in MPTS and LPTS based on gender in both groups and the entire sample (p&gt;0.05). When comparing LPTS values between both groups, a statistically significant difference (p = 0.04) was found, with higher LPTS values in patients in the second group (with ACL graft injury).</p> <p><bold><italic>Conclusion</italic></bold><bold><italic>. </italic></bold>Increased posterior tibial slope, particularly LPTS, is identified as a potential predictor of ACL graft rupture. The study demonstrates the impact of LPTS on the risk of ACL graft rupture (p&lt;0.05) in cases of indirect traumatic injury.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Актуальность.</italic></bold> Разрыв аутотрансплантата передней крестообразной связки (ПКС) имеет многофакторную природу, причем травматический фактор превалирует над остальными причинами. В литературе имеются противоречивые данные относительно влияния заднего наклона большеберцовой кости на риск травматического разрыва трансплантата ПКС.</p> <p><bold><italic>Цель исследования</italic></bold> — определить, существует ли связь между задним наклоном большеберцовой кости и повреждением трансплантата передней крестообразной связки у пациентов, которым уже была проведена реконструкция передней крестообразной связки.</p> <p><bold><italic>Материал и методы. </italic></bold>В моноцентровое когортное ретроспективное исследование вошли пациенты, у которых был диагностирован полный разрыв ПКС и выполнена ее реконструкция по стандартной методике без разрыва аутотрансплантата на момент последнего осмотра. Критерии включения в первую группу: диагностированный травматический разрыв ПКС с последующей реконструкцией; трансплантат из сложенных пополам полусухожильной и нежной мышц (St+Gr); бедренная фиксация кортикальной пуговицей, большеберцовая фиксация — гильза + винт; отсутствие разрыва трансплантата ПКС на момент проведения исследования. В эту группу были отобраны 30 последовательных пациентов (15 мужчин и 15 женщин), средний возраст 36,3 (min 17, max 59) лет. Критерии включения во вторую группу: непрямой травматический механизм разрыва аутотрансплантата ПКС, выполненная ревизионная пластика ПКС. В эту группу вошли 33 пациента (23 мужчины и 10 женщин), средний возраст 33,0 (min 19, max 60) года. У всех пациентов измеряли латеральный (LPTS) и медиальный (MPTS) задний наклон большеберцовой кости на рентгенограммах в боковой проекции.</p> <p><bold><italic>Результаты</italic></bold><bold>.</bold> Медиана времени, прошедшего с момента операции до последнего контрольного осмотра, в первой группе составила 65 мес. (IQR 60; 66); во второй — 48 мес. (IQR 9;84). Медиана MPTS в первой группе составила 7,8° (IQR 5,3;9,4); во второй — 8,5° (IQR 7,5;11). Медиана LPTS в первой группе — 9,9° (IQR 8,4;12,1); во второй — 12,0° (IQR 9;15,4). Не было выявлено статистически значимой разницы между MPTS и LPTS в зависимости от пола в обеих группах и всей выборке в целом (<italic>р</italic>&gt;0,05). При сравнении значений LPTS в обеих группах получена статистически значимая разница (<italic>p</italic> = 0,04) с бóльшим значением LPTS у пациентов второй группы (с повреждением трансплантата ПКС).</p> <p><bold><italic>Заключение. </italic></bold>Одним из возможных предикторов разрыва аутотрансплантата ПКС является увеличенный задний наклон большеберцовой кости. Выявлено влияние латерального заднего наклона большеберцовой кости (LPTS) на риск разрыва аутотрансплантата ПКС (<italic>p</italic>&lt;0,05) при непрямом механизме травмы.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>revision ACL reconstruction</kwd><kwd>anterior cruciate ligament</kwd><kwd>posterior tibial slope</kwd><kwd>ACL graft rupture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>передняя крестообразная связка</kwd><kwd>ревизионная пластика ПКС</kwd><kwd>задний наклон большеберцовой кости</kwd><kwd>разрыв трансплантата ПКС</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Abram S.G.F., Price A.J., Judge A., Beard D.J.
