В исследование были включены 150 пациентов, 48% мужчин и 52% женщин. Возраст больных был в диапазоне от 46 до 82 лет.

Наиболее часто стрессовый перелом недостаточности был выявлен в медиальном мыщелке бедренной кости (79%), на втором месте латеральный мыщелок бедренной кости – 12%. В медиальном мыщелке большеберцовой кости локализовалось 7,9% зон перелома и только 1,1% – в латеральном мыщелке большеберцовой кости. Информативность рентгенографии была низкой: чувствительность – 68,4%, специфичность – 30,0%, точность – 55,1%. Показатели информативности МРТ: чувствительность – 100%, специфичность – 99,0%, точность – 98,0%.</p></sec><sec><title>Выводы</title><p>Выводы.

The study comprised 150 patients including 48% of men and 52% of women. The age of patients ranged from 46 to 82 years.

The most common stress fracture of insufficiency was found in the medial condyle of the femur (79%) with the second most common in the lateral condyle of the femur (12%). Most fracture zones (7.9%) were localized in the medial condyle of the tibia, and only 1.1% of fracture zones were in the lateral condyle of the tibia. The informativeness of radiography was low: sensitivity of 68.4%, specificity of 30.0%, and accuracy of 55.1%. Parameters of magnetic resonance imaging informativeness were as follows: sensitivity of 100%, specificity of 99.0%, and accuracy of 98.0%.</p></sec><sec><title>Conclusion</title><p>Conclusion. Magnetic resonance imaging is the method of choice for stress fracture knee insufficiency because it demonstrated very high indicators of informativeness. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>субхондральный перелом недостаточности</kwd><kwd>МРТ</kwd><kwd>стрессовые переломы</kwd><kwd>спонтанный остеонекроз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>subchondral insufficiency fracture</kwd><kwd>MRI</kwd><kwd>stress fracture</kwd><kwd>spontaneous osteonecrosis</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">Gaillard F., Saber M.
