摘要

目的

基于MRI图像定量测量股骨髁形态学参数，分析股骨滑车高度发育不良的股骨髁前后部几何形状对髌骨不稳(patellar instability，PI)的影响。

方法

回顾性筛选2014年1月至2021年1月在我科接受MRI检查的股骨滑车高度发育不良患者74名，共82例膝关节MRI图像。根据临床诊断和放射影像学检查，进一步将其分为髌骨脱位组(45例)和无髌骨脱位组(37例)。在MRI图像上定量测量两组膝关节股骨髁相关形态学参数，包括后髁角(PCA)、髁内外侧宽度(MLW)、内侧后髁宽度(MPCW)、外侧后髁宽度(LPCW)、内侧前髁长度(MACL)、外侧前髁长度(LACL)、内侧后髁长度(MPCL)和外侧后髁长度(LPCL)。使用组内相关系数(ICC)评估MRI定量测量的观察者内部和观察者之间的可靠性。

结果

髌骨脱位组的MPCW、LACL均小于无髌骨脱位组(

＜0.05)，而组间PCA、MLW、LPCW、MACL、MPCL、LPCL差异均无统计学意义。所有参数的测量结果在观察者内和观察者之间具有较好的一致性(ICC≥0.80)。

结论

髌骨脱位患者的股骨外侧前髁更短，股骨内侧后髁更窄，可能是导致滑车高度发育不良患者发生脱位的危险因素。

Abstract

Objective

To quantitatively measure the morphological parameters of femoral condyle based on MRI images so as to determine the effect of anterior-posterior femoral condyle geometry on patellar instability (PI) in patients with high-grade femoral trochlear dysplasia.

Methods

A total of 82 series of knee joint MRI images from 74 patients with high-grade femoral trochlear dysplasia who underwent MRI scanning in our hospital from January 2014 to January 2021 were retrospectively selected. According to the results of clinical diagnosis and radiological imaging

they were further divided into patellar dislocation group (

=45) and non-patellar dislocation group (

=37). Subsequently

the morphological parameters related to the femoral condyle of knee joint were measured quantitatively in the MRI images

including posterior condylar angle (PCA)

width of medial-lateral epicondyle (MLW)

medial posterior condyle width (MPCW)

lateral posterior condyle width (LPCW)

medial anterior condyle length (MACL)

lateral anterior condyle length (LACL)

medial posterior condyle length (MPCL)

and lateral posterior condyle length (LPCL). Intraclass correlation coefficient (ICC) was used to assess the intra- and inter-observer reliability of the quantitative MRI measurements.

Results

The MPCW and LACL values were significantly lower in the patellar dislocation group than the non-patellar dislocation group (

0.05)

whereas there were no statistical differences in PCA

MLW

LPCW

MACL

MPCL and LPCL values between the 2 groups. The meas

urement results of all parameters had good consistency within and among the observers (ICC≥0.80).

Conclusion

The patients of patellar dislocation have shorter lateral anterior femoral condyle and narrower medial posterior femoral condyle

which may be risk factors for dislocation in those with high-grade trochlear dysplasia.
