Patients were divided into four groups based on the type of deformity. The first group included 33 (24.4%) joints with cam-type FAI, the second group — 72 (53.4%) joints with mixed-type, the third group — 17 (12.6%) joints with dysplasia (LCEA-O&lt;25°) and cam-type deformity of the femoral head-neck junction, and the fourth group — 13 (9.6%) joints with a combination of dysplasia, cam-type deformity, and retroversion of the acetabulum. All patients underwent physical examination and radiographic diagnostics. In patients with borderline dysplasia, the version of the acetabulum was additionally assessed. The iHOT-33 and HOS scales were used to evaluate the preoperative status and postoperative results.</p> <p><bold>Results<italic>. </italic></bold>The best treatment outcome was achieved in the first group of patients, which was statistically significantly different from the results in the third group. The treatment outcomes in the second group of patients did not show statistically significant differences from the first group according to the HOS questionnaire, but differed according to the iHOT-33 scale. The treatment outcomes in the fourth group of patients were almost indistinguishable on the iHOT-33 scale from the first group and on the HOS scale from the second group. In the third group, a statistically significant result on the HOS-Sport subscale was achieved in only 30% of patients, while in other groups it was not less than 58%. Other scales showed a slight superiority of treatment results in the first and fourth groups compared to the second and third groups. In the first years after surgery, all groups of patients showed a significant improvement in sports activity, but after 2 years, there was a tendency for a decrease in patients in the second and third groups.</p> <p><bold>Conclusion<italic>. </italic></bold>The highest results of arthroscopic treatment were shown by patients in the first group with isolated cam-type deformity, slightly worse were results by patients in the second group (with mixed-type). In patients with borderline dysplasia, the effectiveness of arthroscopy depended on the structure of the anterior wall of the acetabulum. The worst result was observed in patients with borderline dysplasia and insufficiently developed anterior wall of the acetabulum — in that group of patients, it is worth preferring isolated periacetabular osteotomy or in combination with arthroscopy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность<italic>. </italic></bold>Фемороацетабулярный импинджмент (ФАИ) является одной из наиболее частых причин болевого синдрома и ограничения подвижности в тазобедренном суставе (ТБС) у лиц молодого и среднего возраста.</p> <p><bold>Цели исследования</bold><bold>:</bold> 1) оценить влияние типа деформации тазобедренного сустава у пациентов с фемороацетабулярным импинджментом на результат лечения; 2) выявить тип деформации тазобедренного сустава, который является оптимальным для коррекции с использованием артроскопии; 3) определить влияние строения вертлужной впадины в условиях пограничной дисплазии на результат лечения.</p> <p><bold>Материал и методы<italic>.</italic></bold><bold> </bold>Выполнено ретроспективное неконтролируемое одноцентровое исследование, в которое вошел 121 пациент (135 тазобедренных суставов), в том числе 49 (40,5%) женщин и 72 (59,5%) мужчины. Пациенты были разделены на 4 группы по типу деформации. В группу 1 включено 33 (24,4%) сустава с cam-типом ФАИ, в группу 2 — 72 (53,4%) сустава с mixed-типом, в группу 3 — 17 (12,6%) суставов с дисплазией (LCEA-O&lt;25°) и сam-типом деформации головки, в группу 4 — 13 (9,6%) суставов с сочетанием дисплазии, сam-типа деформации и ретроверсии вертлужной впадины. Всем пациентам выполняли физикальное обследование и лучевую диагностику. У пациентов с пограничной дисплазией дополнительно оценивали версию вертлужной впадины. Для оценки предоперационного статуса и послеоперационных результатов использовали шкалы iHOT-33 и HOS.</p> <p><bold>Результаты<italic>. </italic></bold>Лучший результат лечения достигнут в группе 1 пациентов, что статистически значимо отличалось от результата в группе 3. Результаты лечения пациентов в группе 2 не имели статистически значимых отличий от группы 1 по опроснику HOS, однако отличались по шкале iHOT-33. Результаты лечения пациентов в группе 4 почти не отличались по шкале iHOT-33 от группы 1 и по шкале HOS от группы 2. В группе 3 по подшкале HOS-Sport статистически значимый результат был достигнут только у 30% пациентов, в то время как в остальных группах он был не ниже 58%. Остальные шкалы показали незначительное превосходство результатов лечения в группах 1 и 4 по сравнению с группами 2 и 3. В первые годы после операции все группы пациентов показывали существенное улучшение спортивной активности, однако спустя 2 года у пациентов групп 2 и 3 наблюдалась тенденция к снижению.</p> <p><bold>Заключение<italic>. </italic></bold>Лучшие результаты артроскопического лечения показали пациенты группы 1 с изолированным cam-типом деформации. Несколько хуже пациенты группы 2 (с mixed-типом). У пациентов c пограничной дисплазией эффективность артроскопии зависит от строения передней стенки вертлужной впадины. Наихудший результат наблюдается у пациентов с пограничной дисплазией и недостаточно развитой передней стенкой вертлужной впадины — при их лечении стоит отдать предпочтение изолированной периацетабулярной остеотомии или в комбинации с артроскопией.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>femoroacetabular impingement</kwd><kwd>hip arthroscopy</kwd><kwd>acetabular dysplasia</kwd><kwd>acetabular retroversion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фемороацетабулярный импинджмент</kwd><kwd>артроскопия</kwd><kwd>дисплазия вертлужной впадины</kwd><kwd>ретроверсия вертлужной впадины</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Leunig M., Casillas M.M., Hamlet M., Hersche O., Nötzli H., Slongo T. et al.
