Furthermore, studies reporting the results of THA in young patients are scarce in our area.</p> <p><bold>The aim of the study </bold>is to report the early experience and clinical results after total hip arthroplasty in patients ≤40 years old from a regional Saudi-Arabian hospital as a representative of the Arab (Middle Eastern) population.</p> <p><bold>Methods. </bold>We conducted a prospective observational study over one year by following all patients (≤40 years) who underwent primary THA at a regional Saudi-Arabin orthopedics center. Twenty-five patients (a mean age of 31.60±6.07 years, and 14 (56%) were males) were eligible for final inclusion. The functional assessment was performed according to the Harris Hip Score (HHS), leg length discrepancy (LLD) was evaluated, and complications at any point were reported.</p> <p><bold>Results. </bold>The commonest indication was advanced avascular necrosis (28%) followed by post-traumatic osteoarthritis (24%) and rheumatoid arthritis (24%). Cementless fixation was utilized in 20 (80%) THAs, and the bearing surface was either metal- or ceramic-on-polyethylene in 92% of THAs. After a mean follow up of 20.0±4.5 months, HHS improved from a pre-operative mean of 29.20±5.29 to 85.48±7.18 (p = 0.0001). Excellent and good results were reported in 84%. All working patients (52%) returned to their jobs after THAs. The leg length discrepancy improved significantly from a pre-operative mean of 2.12±1.01 cm to the last follow up mean of 0.72±0.4 cm, p = 0.0001. Two (8%) patients had superficial wound infections at the time of suture removal, which were treated successfully by daily dressing and antibiotics. None required revision.</p> <p><bold>Conclusions. </bold>Primary total hip arthroplasty is the option for managing end-stage hip disease, even in younger patients when hip preservation surgeries are invalid. Our results showed improved functional outcomes and a return to pre-disease daily activities in most patients, with considerably lower complication incidence.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> — представить ранние клинические результаты тотального эндопротезирования тазобедренного сустава, выполненного в региональном ортопедическом центре Саудовской Аравии пациентам в возрасте 40 лет и младше, представляющим население стран Ближнего Востока.</p> <p><bold>Материал и методы<italic>.</italic></bold> В рамках проспективного наблюдательного исследования все пациенты в возрасте ≤40 лет, перенесшие первичное тотальное эндопротезирование тазобедренного сустава в региональном ортопедическом центре Саудовской Аравии, находились под наблюдением в течение одного года. Двадцать пять пациентов, в том числе 14 (56%) мужчин, соответствовали критериям включения. Средний возраст пациентов составил 31,6±6,1 года. Функциональные показатели оценивали по шкале Harris (HHS), также оценивалась разница в длине нижних конечностей (LLD) и число осложнений на всех этапах наблюдения.</p> <p><bold>Результаты<italic>.</italic></bold> Наиболее распространенным показанием к ТЭТБС был прогрессирующий аваскулярный некроз (28%), за которым следовали посттравматический остеоартрит (24%) и ревматоидный артрит (24%). Бесцементная фиксация использовалась в 20 (80%) случаях. В 92% наблюдений пара трения была либо металлической, либо керамика-полиэтилен. В средние сроки наблюдения 20,0±4,5 мес. показатель по HHS улучшился с предоперационного среднего значения 29,2±5,3 до 85,5±7,5 баллов (<italic>p</italic> = 0,0001). Отличные и хорошие результаты были зарегистрированы у 84%. Все работающие пациенты (52%) вернулись к своей профессиональной деятельности. Показатель LLD улучшился с 2,12±1,01 до 0,72±0,40 см (<italic>p</italic> = 0,0001). У 2 (8%) пациентов во время снятия швов наблюдалась поверхностная раневая инфекция, которая была успешно купирована ежедневными перевязками и антибиотиками. Ни в одном из случаев не потребовалось повторное хирургическое вмешательство.</p> <p><bold>Заключение<italic>.</italic></bold> Первичное тотальное эндопротезирование тазобедренного сустава является методом выбора при лечении терминальной стадии патологии тазобедренного сустава даже у молодых пациентов, когда суставосохраняющие операции уже невозможны. Наш опыт показал хорошие функциональные результаты, возвращение к повседневной деятельности у большинства пациентов и значительно более низкую частоту осложнений.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>total hip arthroplasty</kwd><kwd>young patients</kwd><kwd>Middle Eastern</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тотальное эндопротезирование тазобедренного сустава</kwd><kwd>молодые пациенты</kwd><kwd>Ближний Восток</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lau R.L., Gandhi R., Mahomed S., Mahomed N.
