It is a result of repeated injury of hip structures, that leads to degenerative changes in hip labrum, cartilage and subchondral bone and provokes progressive development of hip osteoarthritis.</p> <p><bold><italic>Aim of study </italic></bold>— to analyze own experience of treating patients with femoroacetabular impingement and identify factors affecting its outcomes.</p> <p><bold><italic>Methods. </italic></bold>Retrospective, uncontrolled, single-center clinical study included 128 patients with FAI which had 150 surgeries on 149 joints in in the period from 2013 to 2021. All patients underwent physical examination and X-ray diagnostics, their FAI type was identified. The alpha angle of external part of femoral head in anterior-posterior position and in the modified Dunn 45° position, as well as Tonnis angle, lateral central-marginal angle in Ogata modification and the height of articular gap along the lateral (LS) and medial edges (MS) of sclerosed acetabulum part were calculated. The i-HOT-33 and HOS scales were used to assess preoperative status and postoperative results.</p> <p><bold><italic>Results.</italic></bold> The average follow-up period was 3.9 years (SD 1.71; min 1.05 and max 8.16). The study included 55 (43.0%) women and 73 (57.0%) men which underwent 64 (42.7%) and 86 (57.3%) surgeries respectively. The most common types of FAI, according to our data, were mixed type (53% of joints) and сam type (27.5% of joints). Insufficient coverage of the femoral head by the acetabulum (borderline dysplasia) in combination with the сam deformity of the femoral head was observed in 18.1%. Pincer-type FAI was observed in 1.4% of joints. We obtained the worst results with a combination of сam deformity and borderline dysplasia in comparison with cam- and mix-type FAI according to the i-HOT-33 and HOS scales. Patients’ age, deep cartilage damage, irreparable labrum damage and height decrease of the lateral part of the articular gap determined negative effect on treatment results according to the i-HOT-33 and HOS scales.</p> <p><bold><italic>Conclusion.</italic></bold> Hip arthroscopy showed good short- and midterm outcomes in patients with FAI. Pain syndrome is most often manifested in patients with pathology of hip soft tissue structures concomitant to FAI. The combination of сam deformity and insufficient femoral head coverage, deep cartilage damage and a height decrease of the articular gap are important predictors of poor treatment results.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Актуальность. </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 в результате повторяющейся травматизации структур сустава, приводящих к дегенеративным изменениям суставной губы, хряща, субхондральной кости и ведущих к прогрессирующему развитию остеоартроза ТБС.</p> <p><bold><italic>Цель исследования</italic></bold> — на основании анализа собственного опыта лечения пациентов с ФАИ выявить факторы, оказывающие влияние на его результат.</p> <p><bold><italic>Материал и методы.</italic></bold> Выполнено ретроспективное неконтролируемое одноцентровое клиническое исследование. В него вошли 128 пациентов (149 суставов) с ФАИ, которым было выполнено 150 операций в период с 2013 по 2021 г. Из них было 55 (43,0%) женщин и 73 (57,0%) мужчины. Средний период наблюдения составил 3,9 лет (SD 1,71; min 1,05; max 8,16). Всем пациентам проведено физикальное обследование и лучевая диагностика с определением типа ФАИ, выполнен расчет угла a головки бедренной кости в прямой проекции и модифицированой укладке Dunn 45°, угла Tönnis, латерального центрально-краевого угла в модификации Ogata, высоты суставной щели по латеральному (LS) и медиальному краям (MS) склерозированной части вертлужой впадины. Для оценки предоперационного статуса и послеоперационных результатов использованы шкалы i-HOT-33 и HOS.</p> <p><bold><italic>Результаты.</italic></bold> Наиболее часто встречались смешанный тип (53% суставов) ФАИ и сam-тип (27,5%) ФАИ. Недостаточное покрытие вертлужной впадины головки бедренной кости (пограничная дисплазия) в сочетании с сam-деформацией головки бедренной кости выявлено в 18,1% суставов. Pincer-тип ФАИ определен в 1,4% суставов. При сравнении результатов лечения по шкалам i-HOT-33 и HOS нами получены наихудшие результаты при сочетании сam-деформации и пограничной дисплазии в сравнении с сam-типом и mix-типом ФАИ. Также выявлено отрицательное влияние на исход лечения более старшего возраста пациента, глубокого повреждения хряща, невосполнимых повреждений суставной губы и снижения высоты латерального отдела суставной щели.</p> <p><bold><italic>Заключение.</italic></bold> Артроскопия тазобедренного сустава показывает хорошие кратко- и среднесрочные результаты при лечении пациентов с ФАИ. Болевой синдром чаще всего проявляется при сопутствующей ФАИ патологии мягкотканных структур тазобедренного сустава. Сочетание сam-деформации и недостаточного покрытия головки бедренной кости вертлужной впадиной, глубокие повреждения хряща, невосполнимые повреждения суставной губы и снижение высоты суставной щели являются важными предикторами неудовлетворитиельных исходов лечения.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>arthroscopy</kwd><kwd>femoroacetabular impingement</kwd><kwd>pincer deformity</kwd><kwd>cam deformity</kwd><kwd>hip dysplasia</kwd><kwd>retroversion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>артроскопия</kwd><kwd>фемороацетабулярный импинджмент</kwd><kwd>pincer-деформация</kwd><kwd>cam-деформация</kwd><kwd>дисплазия</kwd><kwd>ретроверсия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Griffin D.R., Dickenson E.J., O’Donnell J., Agricola R., Awan T., Beck M. et al.
