Артроскопическая лазерная обработка суставного хряща является эффективным и перспективным методом лечения остеоартроза, однако её методика может быть улучшена за счёт результатов данного исследования.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: экспериментальная оценка коэффициентов поглощения и рассеяния лазерных излучений с длинами волн λ=1.55 мкм и λ=0.97 мкм в тканях суставного хряща и установления роли этих излучений в механизме лазерного воздействия при лечении хондропатии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: Из образцов хрящевой ткани свиньи были изготовлены тонкие срезы толщиной 100 мкм и 200 мкм. Срезы подвергались воздействию лазерных излучений с длинами волн λ=1.55 мкм и λ=0.97 мкм. Для измерения оптических свойств образов был использован «метод подвижных интегрирующих сфер».</p></sec><sec><title>Результаты</title><p>Результаты: При прохождении через хрящевую ткань, коэффициент поглощения для излучения λ=0,97 мкм составил 0,14±0,02 мм-1 для излучения λ=1,55 мкм - 0,8±0,1 мм-1. Коэффициент рассеяния для излучений с λ=0.97 и с λ=1.55 составил 19±2 мм-1 и 3,7±0,4 мм-1 соответственно.</p></sec><sec><title>Заключение</title><p>Заключение: 1) При прохождении через толщу суставного хряща коэффициент поглощения (μа) у лазерного излучения с λ=0,97 мкм значительно ниже чем у лазерного излучения с λ=1,55 мкм. 2) При прохождении через толщу суставного хряща коэффициент рассеяния (μs) у лазерного излучения с λ=0,97 мкм значительно выше чем у лазерного излучения с λ=1,55 мкм. При лазерной обработке очага хондропатии сочетанным излучением λ=0,97 мкм + λ=1,55 мкм, излучение λ=1,55 мкм «сглаживает» поверхность суставного хряща в очаге хондромаляции позволяя достигать восстановления структурности суставной поверхности, а параметры излучения λ=0,97 мкм в толще суставного хряща позволяют запустить механизмы фотобиомодуляции в суставном хряще и подлежащей субхондральной кости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Justification</title><p>Justification: Osteoarthritis is one of the most common diseases that lead to disability. Arthroscopic laser treatment of articular cartilage is an effective and promising method of treating osteoarthritis, but its technique can be improved due to the results of this study.</p></sec><sec><title>Purpose</title><p>Purpose: to experimentally evaluate the absorption and scattering coefficients of laser radiation with wavelengths λ=1.55 microns and λ=0.97 microns in articular cartilage tissues and to establish the role of these radiations in the mechanism of laser exposure in the treatment of chondropathy.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: Thin slices with a thickness of 100 microns and 200 microns were made from samples of pig cartilage tissue. The slices were exposed to laser radiation with wavelengths λ=1.55 microns and λ=0.97 microns. The "method of mobile integrating spheres" was used to measure the optical properties of images.</p></sec><sec><title>Results</title><p>Results: When passing through cartilage tissue, the absorption coefficient for radiation λ=0.97 microns was 0.14±0.02 mm-1 for radiation λ=1.55 microns - 0.8±0.1 mm-1. The scattering coefficient for radiations with λ=0.97 and with λ=1.55 was 19±2 mm-1 and 3.7±0.4 mm-1, respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion: 1) When passing through the thickness of articular cartilage, the absorption coefficient (μa) of laser radiation with λ = 0.97 microns is significantly lower than that of laser radiation with λ = 1.55 microns. 2) When passing through the thickness of articular cartilage, the scattering coefficient (μs) of laser radiation with λ= 0.97 microns is significantly higher than that of laser radiation with λ = 1.55 microns. With laser treatment of the focus of chondropathy with combined radiation λ=0.97 microns + λ=1.55 microns, radiation λ=1.55 microns «smoothes» the surface of articular cartilage in the focus of chondromalacia, allowing to achieve restoration of the structure of the articular surface, and the radiation parameters λ=0.97 microns in the thickness of articular cartilage allow to trigger photobiomodulation mechanisms in the articular cartilage and the underlying subchondral bone.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лазер</kwd><kwd>хрящ</kwd><kwd>регенерация</kwd><kwd>хондропатия</kwd><kwd>остеоперфорация</kwd><kwd>абляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser</kwd><kwd>cartilage</kwd><kwd>regeneration</kwd><kwd>chondropathy</kwd><kwd>osteoperforation</kwd><kwd>ablation</kwd><kwd>chondronecrosis</kwd><kwd>arthrosis</kwd><kwd>laser treatment</kwd><kwd>knee joint</kwd><kwd>photobiomodulation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке Министерства науки и высшего образования в рамках выполнения работ по Государственному заданию ФНИЦ «Кристаллография и фотоника» РАН в части развития медицинских технологий.</funding-statement><funding-statement xml:lang="en">The work was partially supported by the Ministry of Science and Higher Education as part of the work on the State assignment of the Federal Research Institute «Crystallography and Photonics» of the Russian Academy of Sciences in terms of the development of medical technologies.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Glyn-Jones S., Palmer A.
