{"cited_by_count":266239,"description":"This cluster of papers focuses on the pathogenesis, natural history, and treatment of osteonecrosis, particularly in the femoral head. It covers topics such as the use of stem cell therapy, core decompression, glucocorticoid-induced osteonecrosis, and the role of bone marrow in the development and diagnosis of osteonecrosis. MRI imaging is also explored for its insights into the condition.","display_name":"Bone and Joint
