摘　　要：目的:研究不明原因股骨外髁后外侧关节面下骨髓水肿与骨性腓肠豆关系。方法:搜集2017年1月至2023年12月于本院行膝关节MRI检查患者18022例,其中不明原因股骨外髁后外侧关节面下骨髓水肿309例作为实验组。随机选择无股骨外髁后外侧关节面下骨髓水肿617例作为对照组。在MRI上比较两组病例骨性腓肠豆发生率及腓肠豆厚度,以及年龄对骨髓水肿、腓肠豆骨发生率及厚度的影响。结果:实验组及对照组骨性腓肠豆骨出现率分别为84.1%、49.4%,前者发生率高于后者(P<0.05)。实验组及对照组骨性腓肠豆平均厚度分别为(6.92±1.67)mm、(5.49±1.44)mm,前者厚度较后者大(P<0.05)。实验组及对照组中50岁及以上的实验对象骨性腓肠豆发生率及其厚度均高于50岁以下的实验对象(P<0.05),而且50岁及以上的病例出现股骨外侧髁后外侧水肿占整个实验组病例的81%。结论:部分不明原因股骨外髁后外侧关节面下骨髓水肿可能是由偏大的骨性腓肠豆与股骨外髁后外侧关节面慢性撞击所致。Objective:To investigate the relationship between the bone marrow edema of posterolateral margin of lateral femoral condyle of unknown cause and the bony fabella.Methods:From January 2017 to December 2023,18022 consecutive patients with knee MRI examination were observed.309 cases with bone marrow edema of posterolateral margin of lateral femoral condyle were selected as the experimental group,617 cases without posterolateral subarticular bone marrow edema were randomly selected as the control group.The incidence and sizes of the bony fabella of the patients in the two groups were measured and compared on MRI.The effects of age on bone marrow edema,the incidence and size of the bony fabella were analyzed.Results:The incidence of the bony fabella in the lesion group and control group were 84.1%and 49.4%respectively,and the incidence of bony fabella in lesion group were significantly greater than in control group(P<0.05).The mean diameter of the bony fabella in two groups were(6.92±1.67)mm and(5.49±1.44)mm respectively,and the size of the bony fabella in the experimental group was significantly greater than that in the control group(P<0.05).In both the experimental group and the control group,the incidence and thickness of bony fabella in subjects aged 50 years and over were higher than those under 50 years old(P<0.05),and the posterolateral margin of lateral femoral condyle edema in patients aged 50 years and over accounted for 81%of the whole experimental group.Conclusion:Some bone marrow edema of posterolateral margin of lateral femoral condyle of unknown cause might be caused by chronic impact of larger bony fabella on the posterolateral articular surface of lateral femoral condyle.
