Timely detection of avascular necrosis is important in the prevention of osteoarthrosis and other complications.</p> <p>We present a clinical case of a 54-year-old patient hospitalized for novel coronavirus infection with complaints of severe pain in both knees 2 weeks after the disease onset. Magnetic resonance imaging revealed pronounced changes in both knees, corresponding to avascular necrosis. The results of conservative therapy, including non-steroidal anti-inflammatory drugs and bisphosphonate bone resorption inhibitors, produced a pronounced positive result. At follow-up examination 3 months later, there was no pain, but the knee joints still had slight restrictions of movement. Magnetic resonance imaging showed a significant decrease in the previously detected changes.</p> <p>The side effects of glucocorticoids (impaired glucose tolerance, increased blood pressure, tachycardia, gastrointestinal erosive ulcers, sleep disorders, etc.) are widely known, but knee osteonecrosis caused by steroid intake rarely comes to the attention of clinicians. This clinical case emphasizes the complex nature of osteonecrosis pathogenesis and demonstrates a wide range of complications in corticosteroid therapy.</p></abstract><trans-abstract xml:lang="ru"><p>Развитие аваскулярного некроза костных структур, индуцированного лечением новой коронавирусной инфекции глюкокортикоидами, является довольно распространённым осложнением терапии, при этом чаще всего встречается поражение головок бедренных костей. Своевременное выявление аваскулярного некроза важно в рамках профилактики развития артритов и других осложнений.</p> <p>В работе представлен клинический случай пациентки в возрасте 54 лет, госпитализированной по поводу новой коронавирусной инфекции, с жалобами на выраженные боли в обоих коленных суставах через 2 недели от начала болезни. По результатам магнитно-резонансной томографии был выявлен выраженный аваскулярный некроз костей, формирующих коленный сустав, с обеих сторон. Консервативная терапия, включающая приём нестероидных противовоспалительных препаратов и ингибиторов костной резорбции из группы бисфосфонатов, дала выраженный положительный результат. При повторном осмотре через 3 месяца болей нет, сохраняются небольшие ограничения движений в коленных суставах. По данным магнитно-резонансной томографии обоих коленных суставов отмечено значительное уменьшение ранее выявленных изменений.</p> <p>Побочные эффекты глюкокортикоидов (нарушение толерантности к глюкозе, повышение артериального давления, тахикардия, эрозивно-язвенное поражение желудочно-кишечного тракта, нарушения сна и др.) широко известны, однако остеонекроз костных структур коленных суставов, вызванный приёмом стероидов, редко попадает в поле зрения клиницистов. Приведённый клинический случай подчёркивает комплексный характер патогенеза остеонекроза и демонстрирует широкий спектр осложнений при терапии кортикостероидами.</p></trans-abstract><trans-abstract xml:lang="zh"><p>糖皮质激素治疗新型冠状病毒感染引起的骨结构缺血性坏死是一种相当常见的治疗并发症，其中最常见的是股骨头病变。对于预防关节炎和其他并发症，及时检测缺血性坏死是很重要的。</p> <p>这项研究展示了一名54岁的患者的临床案例，她因新冠状病毒感染住院，并在发病后两周内抱怨双膝关节疼痛。磁共振成像扫描显示，形成膝关节的骨骼在两侧都有明显的血管性坏死。使用非甾体抗炎药和双磷酸盐骨吸收抑制剂的保守治疗有显著的积极效果。3个月后复查时，没有疼痛，但膝关节的活动仍有轻微限制。两个膝关节的磁共振成像显示，先前确定的变化明显减少。</p> <p>糖皮质激素的副作用（糖耐量受损、血压升高、心动过速、胃肠道侵蚀性溃疡、睡眠障碍等）广为人知，但由类固醇引起的膝关节骨结构的骨坏死却很少引起临床医生的注意。这个临床病例强调了骨坏死发病机制的复杂性，并展示了皮质类固醇治疗的广泛并发症。</p></trans-abstract><kwd-group xml:lang="en"><kwd>сase report</kwd><kwd>avascular necrosis</kwd><kwd>osteonecrosis</kwd><kwd>COVID-19</kwd><kwd>knee joint</kwd><kwd>magnetic resonance imaging</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>клинический случай</kwd><kwd>аваскулярный некроз</kwd><kwd>остеонекроз</kwd><kwd>коронавирусная инфекция</kwd><kwd>коленный сустав</kwd><kwd>магнитно-резонансная томография</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>临床病例</kwd><kwd>缺血性坏死</kwd><kwd>骨坏死</kwd><kwd>冠状病毒感染</kwd><kwd>膝关节</kwd><kwd>磁共振成像</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Temporary guidelines «Prevention, diagnosis and treatment of new coronavirus infection (COVID-19)».
