2024年12月5日 · Spontaneous osteonecrosis of the knee (SONK) is an idiopathic condition that leads to the development of a crescent shaped osteonecrosis lesion, mostly commonly in the epiphysis of the medial femoral condyle. Diagnosis can be radiographic for advanced disease but may require MRI in determining the extent of disease.

2024年12月10日 · Subchondral insufficiency fracture of the knee (SIF/SIFK) are stress fractures in the femoral condyles or tibial plateau that occur in the absence of acute trauma, typically affecting older adults. The entity subsumes that previously known as spontaneous osteonecrosis of the knee (SONK/SPONK) or Ahlbäck disease.

2024年2月28日 · Spontaneous osteonecrosis of the knee primarily affects the subchondral bone of the medial femoral condyles due to weight-bearing stress, and involvement of the lateral femoral condyles and tibial plateau is less common.

2024年12月4日 · 其實「膝關節自發性骨壞死 （Spontaneous OsteoNecrosis of Knee, SONK）」這個聽起來很可怕的醫學名詞是過去的名稱，現在的研究發現在組織切片下，主要是呈現軟骨下骨小樑的骨折，並搭配周圍骨頭內的水腫，只有在較為末期的患者骨頭才呈現壞死狀態。

MRI features are suggestive of spontaneous osteonecrosis of the knee (SONK) involving the medial femoral condyle. It is usually a diagnosis in an older age group (>55 years) with a female predilection and usually unilateral, mostly affecting medial tibial plateau.

2022年8月31日 · 诊断sonk的首选检查方法是mri检查，它已被证明具有既敏感又特异的特点。 在MRI扫描中，发现骨髓水肿、T1和T2序列上的软骨下新月形线性病灶、局灶性骨骺轮廓凹陷或软骨下低信号，可能提示SONK的发生。

Spontaneous osteonecrosis of the knee is the result of vascular arterial insufficiency to the medial femoral condyle of the knee resulting in necrosis and destruction of bone. It is often unilateral and can be associated with a meniscal tear. [1]

SONK又作SPONK，是英文 Spontaneous osteonecrosis of the knee 的缩写，我们可以理解为自发性的骨坏死，Spontaneous这里有primary的意思，强调在病因学上不明确的一种自发性的骨坏死现象。

2022年6月18日 · 膝关节自发性骨坏死(Spontaneous osteonecrosis of the knee，SONK)由 Ahlback 等人于1968年首次提及，当时被其描述为“软骨下骨的一种特殊的射线可透性病变”。 SONK 是一种相对常见的疾病，通常被描述为局灶性软骨下病变，可能导致膝关节的终末期骨关节 …
