Subchondral insufficiency fracture of the knee (SIFK) is a potentially devastating disorder that may progress rapidly to osteoarthritis with articular surface collapse. It should be suspected in the appropriate clinical setting, as in early stages it is usually indistinct on initial plain radiographs and magnetic resonance imaging is required for a definitive diagnosis. Outcome of SIFK depends on several factors, including the initial subchondral fracture size, patient BMI, degree of osteopenia, as well as early diagnosis and initial treatment. The purpose of this paper is to review the clinical presentation, pathophysiology, image findings, complications and outcome of SIFK.
膝关节软骨下不全骨折（SIFK）是一种潜在的破坏性疾病，可能迅速发展为伴有关节面塌陷的骨关节炎。在适当的临床情况下应怀疑此病，因为在早期，其在初次X线平片上通常不明显，需要磁共振成像才能做出明确诊断。SIFK的预后取决于几个因素，包括初始软骨下骨折的大小、患者体重指数、骨质减少程度以及早期诊断和初始治疗。本文的目的是综述SIFK的临床表现、病理生理学、影像学表现、并发症及预后。
