Mechanism of destruction of the articular cartilage includes chondroresorption of superficial layers of the articular cartilage by hypercellular fibrous tissue (pannus), loosening, separation of fibers and lysis of cartilagenous matrix, sometimes with necrosis of superficial cartilagenous zone and subchondral bone lamina accompanied by chronic nonspecific inflammation. Activity of chondroosteoresorption resulting in articular cartilage destruction is higher during early term of chondrolysis (up to 1 year since the onset of the disease) and the longer the pathological process lasts, the higher is the degree of the cartilagenous matrix dystrophy.</p></abstract><trans-abstract xml:lang="ru"><p>Проведено патогистологическое исследование биоптатов суставной поверхности, спопгиозы головки, суставной капсулы, полученных при оперативном лечении 15 больных с хондролизом тазобедренных суставов с давностью клинико-рентгенологических симптомов от 8 мес до 4 лет. Изучены механизмы разрушения суставного хряща, субхондралыюй костной пластинки головки, патологические изменения суставной капсулы. Среди механизмов разрушения суставного хряща — хондрорезорбция поверхностных слоев гиперцеллюлярной фиброзной тканью (паннусом), разрыхление, разволокнение и лизис хрящевого матрикса, иногда некроз поверхностной зоны хряща; остеохондрорезорбция глубокой зоны суставного хряща и субхопдральной пластинки, сопровождающаяся хроническим неспецифическим воспалением. Активность процессов хондроостеорезорбции, разрушающих суставной хрящ, выше в ранние сроки хондролиза (до года от появления клинических симптомов), а степень дистрофии хрящевого матрикса нарастает с увеличением давности заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chondrolysis</kwd><kwd>biopsy</kwd><kwd>joint capsule</kwd><kwd>chondrosteoresorption</kwd><kwd>lysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хондролиз</kwd><kwd>биоптат</kwd><kwd>суставная капсула</kwd><kwd>хондроостеорезорбция</kwd><kwd>лизис</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Павлова В.Н., Копьева Т.Н., Слуцкий Л.И., Павлов Г.Г.
