The surgery outcomes depend on an accurate assessment of the anatomical and functional characteristics of the foot. Clinical gait analysis was performed using the computerized hardware-software system F-Scan Mobile.</p> <p><bold>AIM: </bold>This study aimed to evaluate biomechanical gait parameters in patients with deformities of the ankle and foot before and after surgery.</p> <p><bold>METHODS: </bold>A single-center, prospective, non-randomized, controlled, experimental, quantitative, cohort study was conducted at the Department of Traumatology and Orthopedics No. 4 of the Priorov National Medical Research Center of Traumatology and Orthopedics (Moscow) during 2022–2024. A total of 102 patients with ankle arthrosis and post-traumatic calcaneal deformity were treated, including 68 men and 34 women, a mean age of 39 ± 17.61 years. All patients also underwent biomechanical assessment of functional foot parameters.</p> <p><bold>RESULTS:</bold><bold> </bold>Treatment outcomes in patients included in the study were assessed 12 and 24 months after surgery. The mean follow-up period was 22.3 ± 9.42 months. The mean visual analog scale score before surgery was 6.5 ± 3.63, and 1.6 ± 0.81 after surgery, indicating a significant reduction in pain (<italic>p</italic> &lt; 0.05). The mean AOFAS hindfoot score increased from 38 ± 23.31 preoperatively to 88 ± 10.55 postoperatively, with a significant improvement in questionnaire scores (<italic>p</italic> &lt; 0.05). Subjective evaluation of treatment outcomes: 56 patients (54.9%) rated the results as excellent, 30 (29.4%) as good, 14 (13.7%) as satisfactory, and 2 (1.9%) as unsatisfactory.</p> <p><bold>CONCLUSION: </bold>The clinical model for biomechanical gait assessment provides objective data on the structure of the gait cycle in unilateral foot lesions and allows evaluating the adequacy of adaptive motor skills in patients before and after surgery, as well as during long-term follow-up. Patients were satisfied with the treatment outcomes, confirmed both clinically and through biomechanical assessment.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Изменение походки пациента после оперативного лечения на голеностопном суставе и стопе связано с развитием биомеханически обусловленных осложнений. Результаты оперативного лечения зависят от правильной оценки анатомо-функциональных особенностей стопы. Клинический анализ ходьбы проводился с помощью компьютеризированного аппаратно-программного комплекса «F-Scan Mobile».</p> <p><bold>Цель. </bold>Оценить биомеханические показатели ходьбы у пациентов с деформацией голеностопного сустава и стоп до и после оперативного лечения.</p> <p><bold>Материалы и методы. </bold>В отделении травматологии и ортопедии № 4 ФГБУ «НМИЦ ТО им. Н.Н. Приорова» (г. Москва) в период 2022–2024 гг. проведено одноцентровое проспективное нерандомизированное когортное контролируемое экспериментальное количественное исследование. Были прооперированы 102 пациента с крузартрозом и посттравматической деформацией пяточной кости, из них 68 мужчин и 34 женщины, средний возраст которых составил 39 ± 17,61 года. Также пациентам проводилась биомеханическая оценка функциональных параметров стопы.</p> <p><bold>Результаты. </bold>Оценка результатов лечения пациентов, принявших участие в исследовании, проводились в интервале 12 и 24 мес. после операции. Средний период наблюдения составил 22,3 ± 9,42 мес. Средний показатель визуально-аналоговой шкалы до операции составил 6,5 ± 3,63, после операции — 1,6 ± 0,81, отмечено значительное снижение болевого синдрома (<italic>р</italic> &lt; 0,05). Средний показатель AOFAS заднего отдела стопы до операции составил 38 ± 23,31, после операции — 88 ± 10,55, также отмечено улучшение показателей опросника (<italic>р</italic> &lt; 0,05). Субъективная оценка результатов лечения: 56 пациентов (54,9%) — отличный результат, 30 пациентов (29,4%) — хороший, 14 пациентов (13,7%) — удовлетворительный, 2 пациента (1,9%) оценили результат лечения как неудовлетворительный.</p> <p><bold>Заключение.</bold> Разработанная<bold> </bold>клиническая модель биомеханической оценки параметров ходьбы позволяет получать объективные данные о структуре цикла шага при одностороннем поражении стоп и оценить адекватность адаптивного двигательного навыка у больных до и после оперативного лечения и в отдалённом периоде наблюдений. Пациенты были удовлетворены результатом лечения, который был подтверждён не только клинически, но и путём биомеханического исследования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gait analysis</kwd><kwd>ankle arthrosis</kwd><kwd>post-traumatic deformity</kwd><kwd>subtalar arthrodesis</kwd><kwd>supramalleolar osteotomy</kwd><kwd>ankle arthroplasty</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>анализ походки</kwd><kwd>крузартроз</kwd><kwd>посттравматическая деформация</kwd><kwd>подтаранный артродез</kwd><kwd>надлодыжечная остеотомия</kwd><kwd>эндопротезирование голеностопного сустава</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bernstein M, Reidler J, Fragomen A, Rozbruch SR.
