The most debated aspects include the type of capsulotomy, the method of acetabular labrum refixation, and the accuracy of cam deformity correction. The influence of different technical options at the key stages of hip arthroscopy on morphological and clinical outcomes in patients with FAI remains insufficiently studied.</p> <p><bold>The aim of the study</bold> — to compare morphological and clinical outcomes of arthroscopic treatment in patients with femoroacetabular impingement managed with standard versus modified surgical strategy.</p> <p><bold>Methods.</bold> A single-center comparative cohort study included 88 patients who underwent 94 hip arthroscopic procedures. The retrospective group comprised 61 patients (64 hips), the prospective group — 27 patients (30 hips). The modified strategy included longitudinal capsulotomy with capsular closure, avoidance of knotted acetabular labral anchors, and a modified method of preoperative planning and intraoperative execution of cam deformity correction. Clinical outcomes were assessed preoperatively and at 12 months postoperatively using the iHOT-33, HOS-ADL, and HOS-Sport. Morphological outcomes were evaluated using Dunn 45° X-rays and follow-up magnetic resonance imaging.</p> <p><bold>Results.</bold> Before surgery, the groups did not differ in most demographic, clinical, and radiographic characteristics; the only statistically significant baseline difference was found for HOS-ADL. Postoperatively, the prospective group demonstrated a higher iHOT-33 score than the retrospective group (90.4 [81.3; 96.2] vs 80.4 [71.8; 90.8] points; p = 0.002), while score improvement was greater for iHOT-33 (38.3 [29.3; 50.3] vs 23.5 [10.3; 39.5] points; p = 0.003), HOS-ADL (32.5 [13.2; 42.6] vs 11.8 [5.5; 23.2] points; p = 0.005), and HOS-Sport (37.5 [25.0; 53.5] vs 20.8 [5.6; 45.1] points; p = 0.038). The rate of achieving substantial clinical benefit for iHOT-33 was higher in the prospective group: 26/30 (86.7%; 95% CI 69.3-96.2) vs 28/64 (43.8%; 95% CI 31.4-56.7); p &lt; 0.001. The modified strategy was associated with a lower postoperative alpha angle, a higher femoral head-neck offset ratio, a higher rate of spherical femoroplasty, more frequent complete capsular healing on MRI, and a lower rate of anchor-related MRI changes in analyses by anchor type.</p> <p><bold>Conclusion.</bold> The use of a modified arthroscopic strategy in patients with femoroacetabular impingement was associated with more favorable morphological and clinical outcomes compared with the standard approach. In reduced multivariable models, non-intact capsular status demonstrated the most stable association with smaller improvement in clinical rating scale scores and failure to achieve clinically meaningful thresholds.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Результаты артроскопического лечения фемороацетабулярного импинджмента (ФАИ) остаются вариабельными. К числу наиболее дискуссионных аспектов относятся тип капсулотомии, способ рефиксации вертлужной губы и точность коррекции cam-деформации. Недостаточно изучено влияние различных вариантов выполнения ключевых этапов артроскопического вмешательства на морфологические и клинические исходы лечения пациентов с ФАИ.</p> <p><bold>Цель исследования</bold> — сравнить морфологические и клинические исходы артроскопического лечения пациентов с фемороацетабулярным импинджментом при использовании стандартной и усовершенствованной хирургической техники.</p> <p><bold>Материал и методы.</bold> Проведено одноцентровое сравнительное когортное исследование, включившее 88 пациентов, которым были выполнены 94 артроскопических вмешательства на тазобедренном суставе. В ретроспективную группу вошел 61 пациент (64 тазобедренных сустава), в проспективную — 27 пациентов (30 тазобедренных суставов). Усовершенствованная техника включала продольную капсулотомию с ушиванием капсулы, отказ от использования узловых фиксаторов вертлужной губы и модифицированный способ предоперационного планирования и интраоперационной реализации коррекции cam-деформации. Клинические исходы оценивали до операции и через 12 мес. после с использованием iHOT-33, HOS-ADL и HOS-Sport. Морфологические исходы анализировали по данным рентгенографии в укладке Dunn 45° и контрольной магнитно-резонансной томографии.</p> <p><bold>Результаты.</bold> До операции группы не различались по большинству демографических, клинических и рентгенологических характеристик; статистически значимое различие выявлено только по шкале HOS-ADL. После операции показатель iHOT-33 в проспективной группе был выше, чем в ретроспективной (90,4 [81,3; 96,2] против 80,4 [71,8; 90,8] балла; <italic>p </italic>= 0,002), а прирост показателей был больше по iHOT-33 (38,3 [29,3; 50,3] против 23,5 [10,3; 39,5] балла; <italic>p </italic>= 0,003), HOS-ADL (32,5 [13,2; 42,6] против 11,8 [5,5; 23,2] балла; <italic>p </italic>=<italic> </italic>0,005) и HOS-Sport (37,5 [25,0; 53,5] против 20,8 [5,6; 45,1] балла; <italic>p </italic>= 0,038). Частота достижения существенного клинического улучшения по iHOT-33 была выше в проспективной группе: 26/30 (86,7%; 95% ДИ 69,3–96,2) против 28/64 (43,8%; 95% ДИ 31,4–56,7); <italic>p</italic> &lt; 0,001. Применение усовершенствованной тактики ассоциировалось с более низким послеоперационным α-углом, более высоким офсетным коэффициентом, с достижением большей частоты сферической феморопластики, более частым полноценным заживлением капсулы по данным МРТ и меньшей частотой изменений в области фиксаторов при анализе типа фиксации.</p> <p><bold>Заключение.</bold> Применение усовершенствованной артроскопической техники у пациентов с ФАИ ассоциировалось с более благоприятными морфологическими и клиническими исходами по сравнению со стандартным подходом. В многофакторных моделях наиболее устойчивая связь с меньшим приростом баллов по используемым шкалам клинической оценки и недостижением клинически значимых порогов выявлена для неинтактного состояния капсулы.</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>cam deformity</kwd><kwd>capsulotomy</kwd><kwd>acetabular labrum</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фемороацетабулярный импинджмент</kwd><kwd>артроскопия тазобедренного сустава</kwd><kwd>cam-деформация</kwd><kwd>капсулотомия</kwd><kwd>вертлужная губа</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.
