The relationship between spontaneous osteonecrosis of the knee (SONK) and ipsilateral meniscus tear remains to be established, and the possible causes are clarified and summarized.
We conducted a search in Pubmed, Web of Science, Embase, and the Cochrane Library to include all English articles published from the establishment of the database until April 2023. The odds ratio (OR) and 95% confidence interval (CI) were calculated to evaluate the relationship between SONK and ipsilateral meniscus lesions.
A total of 405 patients were included in eight articles, including 157 males and 248 females, with an average age of 63.94 years and an average BMI of 26.36 kg/m. In patients with medial SONK, the prevalence of ipsilateral meniscus tear was 0.8982, 95% CI (0.7389, 0.9648), and the prevalence of ipsilateral posterior root tear was 0.6198, 95% CI (0.5169, 0.7118). The prevalence of ipsilateral meniscus tears in patients with lateral SONK was 0.2188, 95% CI (0.1150, 0.3711), and the prevalence of ipsilateral posterior root tears was 0.1667, 95% CI (0.1071, 0.2424).
SONK is significantly associated with meniscus or root tears, which limit meniscus function and lead to changes in the stress environment between the knee and the tibiofemur, increasing the chance of incomplete fracture. We suggest that the expression of SONK can be replaced with subchondral insufficiency fracture of the knee.

膝关节自发性骨坏死（SONK）与同侧半月板撕裂之间的关系尚待明确，对可能的病因进行梳理总结。
在PubMed、Web of Science、Embase和Cochrane图书馆进行检索，纳入数据库建立至2023年4月发表的所有英文文章。计算比值比（OR）和95%置信区间（CI），以评估SONK与同侧半月板损伤之间的关系。
8篇文章共纳入405例患者，其中男性157例，女性248例，平均年龄63.94岁，平均体重指数26.36kg/m。内侧SONK患者中，同侧半月板撕裂的患病率为0.8982，95%CI（0.7389，0.9648），同侧后根撕裂的患病率为0.6198，95%CI（0.5169，0.7118）。外侧SONK患者中，同侧半月板撕裂的患病率为0.2188，95%CI（0.1150，0.3711），同侧后根撕裂的患病率为0.1667，95%CI（0.1071，0.2424）。
SONK与半月板或根部撕裂显著相关，这会限制半月板功能，导致膝关节与胫股之间应力环境改变，增加不完全骨折的几率。我们建议SONK的表述可被膝关节软骨下不全骨折所替代。
