摘要:

文题释义:
髌下脂肪垫:也称Hoffa脂肪垫,是一种以弹性纤维作为网状支架的脂肪体结构。其性质柔软,易移动,外由滑膜覆盖,位于膝关节的髌骨、股骨髁前方、胫骨髁上方和髌韧带之间区域。
滑车形态:也称股骨滑车沟解剖学形态,在轴位MRI图像上通过滑车内侧倾斜度、滑车外侧倾斜度、滑车角度及滑车沟角测量滑车形态;也有研究在MRI上对软骨损伤和软骨下骨髓水肿样病变进行分级。

背景:以往研究认为外上侧髌下脂肪垫水肿是由髌腱和股骨外侧髁之间的摩擦引起的,而外上侧髌下脂肪垫水肿与滑车形态及髌股关节排列的关系尚不清楚。
目的:评估MRI上髌股关节排列、滑车形态与外上侧髌下脂肪垫水肿的相关性。
方法:回顾性分析南华大学附属第一医院2018年7月至2019年10月拍摄的膝前痛或疑有膝骨关节炎风险患者的膝关节MRI影像资料,评估髌股关节排列(髌骨偏移、髌骨倾斜角和Insall-Salati比率)、滑车形态(滑车沟角、滑车外、内侧倾斜角以及滑车角度)和外上侧髌下脂肪垫水肿。髌股关节排列和滑车形态的测量数据被分成四分位数,并确定外上侧髌下脂肪垫的有或无。采用Logistic回归模型,通过调整年龄、性别及体质量指数,确定髌股关节排列、滑车形态与外上侧髌下脂肪垫水肿的关系。

结果与结论:①最终纳入患者161例,其中60例(37.3%)出现外上侧髌下脂肪垫水肿;②滑车角度、Insall-Salati比值和髌股偏移是预测外上侧髌下脂肪垫水肿的正相关因素(P < 0.001);③与测量最低四分位数的膝关节相比,滑车角度、Insall-Salati比值和髌股偏移在最高四分位数的膝关节出现外上侧髌下脂肪垫水肿的可能性分别是7.4倍(95%CI:1.39,5.12)、8.1倍(95%CI:3.27,24.50)和16.2倍(95%CI:4.1,28.8);④在膝前痛或疑有膝骨关节炎风险的中老年人中,滑车角度增大、高位髌骨和髌骨偏移可提示外上侧髌下脂肪垫水肿。

Abstract: BACKGROUND: Previous studies have suggested that edema of the lateral superior infrapatellar fat pad is caused by friction between the patellar tendon and the lateral condyle of the femur, but the relationship between lateral superior infrapatellar fat pad edema and the shape of the pulley and the arrangement of the patellofemoral joint is not clear.    
OBJECTIVE: To evaluate the correlation between patellofemoral joint alignment, pulley shape, and lateral superior infrapatellar fat pad edema on MRI.
METHODS: The MRI images of knee joint taken by the First Affiliated Hospital of South China University from July 2018 to October 2019 were analyzed retrospectively. Patellofemoral joint alignment (patellar offset, patellar tilt angle and Insall-Salati ratio), pulley shape (pulley groove angle, external pulley angle, medial inclination angle and pulley angle) and SIFP edema were evaluated by MRI images of the knee joint. The arrangement of the patellofemoral joint and the shape of the pulley were divided into quartiles and the presence or absence of SIFP was determined. Logistic regression model was used to determine the relationship between patellofemoral joint arrangement, pulley shape and SIFP edema by adjusting age, sex, and body mass index. 
RESULTS AND CONCLUSION: (1) Finally, 161 patients were included, of which 60 cases (37.3%) developed SIFP edema. (2) Trochlear angle, Insall-Salati ratio and patellofemoral deviation were positively correlated with edema of lateral superior infrapatellar fat pad (P < 0.001). (3) Compared with the knee joint measured in the lowest quartile, the trochlear angle, Insall-Salati ratio and patellofemoral offset in the highest quartile were 7.4 times (95%CI: 1.39, 5.12) more likely to develop SIFP edema, 8.1 times (95%CI: 3.27, 24.5) and 16.2 times (95%CI: 4.1, 28.8), respectively. (4) In middle-aged and elderly patients with anterior knee pain or suspected knee osteoarthritis, increased pulley angle and high patella and patellar offset may indicate edema of the lateral superior infrapatellar fat pad.
