Хронические заболевания вен в целом и варикозная болезнь нижних конечностей в частности представляют собой серьезную медико-социальную проблему.</p><p>Цель – изучить влияние терапии нарушений венозного оттока на результаты лечения остеоартроза коленных суставов у больных с варикозной болезнью в сочетании с остеоартрозом коленных суставов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование было включено 105 пациентов с варикозной болезнью в сочетании с артрозом коленных суставов, которые ранее получали лечение остеоартроза коленных суставов, но не получали или получали крайне нерегулярно терапию по поводу варикозной болезни. Срок наблюдения за пациентами составил 12 мес. Пациентам проводился первый курс терапии флеботропными лекарственными препаратами в течение 2 мес. с момента начала исследования. Затем этот курс повторялся 2 раза с интервалом в 3 мес. Стандартным флеботропным лекарственным препаратом являлась микронизированная очищенная флавоноидная фракция. Всем пациентам рекомендовалось использование компрессионного трикотажа. В подавляющем большинстве случаев использовались чулки или колготы 2-го класса с давлением на уровне лодыжек 23–32 мм рт. ст. Терапия остеоартроза включала применение нестероидных противовоспалительных препаратов, болезнь-модифицирующих препаратов (хондроитина сульфат, глюкозамина сульфат), физиотерапевтическое лечение.</p></sec><sec><title>Результаты</title><p>Результаты. По шкале VCSS отмечено снижение степени хронической венозной недостаточности в клинической группе. При включении в исследование средняя сумма баллов в клинической группе равнялась 7,1 ± 1,9, через 6 мес. был получен результат 6,1 ± 1,5, а через 12 мес. – 6,0 ± 1,2 баллов. В контрольной группе, где пациенты не получали терапию, по поводу варикозной болезни, динамика отсутствовала. На фоне коррекции нарушений венозного оттока – течение суставного синдрома изменилось: снизились показатели индекса Лекена и WOMAC, уменьшился болевой синдром по визуально-аналоговой шкале. Всё это привело к снижению потребности в приёме анальгетиков.</p></sec><sec><title>Выводы</title><p>Выводы. Из 100 пациентов с суставной патологией у 68 диагностируется варикозная болезнь. Эти заболевания отягощают друг друга, но можно предположить, что венозная патология является первичной. Запускается порочный круг – прогрессирование остеоартроза за счет нарушений венозного оттока, так и варикозной болезни за счет ухудшения работы мышечно-венозной помпы.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Chronic vein diseases in general and varicose veins of the lower extremities in particular represent a serious medical and social problem.</p><p>The aim was to study the influence of the therapy of venous outflow disorders on the treatment results of osteoarthritis of the knee joints in patients with varicose veins in combination with osteoarthritis of the knee joints.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 105 patients with varicose veins combined with knee osteoarthritis who had previously received treatment for osteoarthritis of the knee joints but had not received or had received extremely irregular therapy for varicose veins. The follow-up period for the patients was 12 months. The patients underwent the first course of phlebotropic drugs for 2 months from the start of the study. Then this course was repeated twice at 3-month intervals. The standard phlebotropic drug was a micronized purified flavonoid fraction. Compression knitwear was recommended in all patients. Class 2 stockings or tights with an ankle pressure of 23–32 mmHg were used in the vast majority of cases. Treatment of osteoarthritis included the use of nonsteroidal anti-inflammatory drugs, disease-modifying agents (chondroitin sulfate, glucosamine sulfate), and physical therapy.</p></sec><sec><title>Results</title><p>Results. The VCSS scale reduced the degree of chronic venous insufficiency in the clinical group. At inclusion in the study, the average score in the clinical group was 7.1 ± 1.9, after 6 months the result was 6.1 ± 1.5, and after 12 months – 6.0 ± 1.2 points. In the control group, where patients did not receive therapy for varicose veins, there were no dynamics. The results of joint syndrome against the background of correction of venous outflow disturbances – decrease of Leken and WOMAC index values, decrease of pain syndrome according to the visual analogue scale. All this led to a decrease in the patients' need for taking analgesics.</p></sec><sec><title>Conclusions</title><p>Conclusions. Out of 100 patients with joint pathology, 68 patients were diagnosed with varicose veins. These diseases aggravate each other, but we can assume that the venous pathology is primary. A vicious circle is set in motion – progression of osteoarthritis due to the disturbances of venous outflow, and varicosity due to the deterioration of muscular-venous pump functioning.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>варикозная болезнь</kwd><kwd>артроз коленных суставов</kwd><kwd>гонартроз</kwd><kwd>хроническая венозная недостаточность</kwd><kwd>микронизированная очищенная флавоноидная фракция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>varicose veins</kwd><kwd>arthrosis of knee joints</kwd><kwd>gonarthrosis</kwd><kwd>chronic venous insufficiency</kwd><kwd>micronized purified flavonoid fraction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rabe E., Guex J.J., Puskas A., Scuderi A., Fernandez Quesada F.
