We aimed to verify the feasibility of using shear wave elastography (SWE) to quantify knee scars and the elastic modulus of scar tissues. Overall, 16 participants underwent SWE assessments and range-of-motion measurement and completed the Knee Injury and Osteoarthritis Outcome Score. The inter-rater reliability for SWE in the suprapatellar bursa, below the patellar tendon, and in the medial and lateral trochlear groove remained within 0.861-0.907. The SWE values in the four regions increased with increasing knee angle, and significant differences were observed between the values for below the patellar tendon and the suprapatellar bursa at knee flexion angles of 60° and 90°. The SWE values of the medial and lateral trochlear groove at 30°, 60°, and 90° knee flexion were higher on the affected side. A negative correlation was observed between the SWE values for the lateral trochlear groove at 0°, 30°, and 60° and those for below the patellar tendon at 0° and the suprapatellar bursa at 30° with both active and passive knee extension. The suprapatellar bursa value at 60° exhibited a positive correlation with both knee flexion and passive knee flexion, whereas that of the suprapatellar bursa at 90° exhibited a positive correlation with both the range of motion and passive range of motion. SWE is a replicable and effective method for detecting scar strength in the knee joint.
我们旨在验证使用剪切波弹性成像（SWE）量化膝关节瘢痕及瘢痕组织弹性模量的可行性。总体而言，16名参与者接受了SWE评估和活动范围测量，并完成了膝关节损伤和骨关节炎疗效评分。髌上囊、髌腱下方以及内侧和外侧滑车沟处SWE的评分者间信度保持在0.861 - 0.907之间。四个区域的SWE值随膝关节角度增加而升高，在膝关节屈曲角度为60°和90°时，髌腱下方和髌上囊的值之间存在显著差异。在膝关节屈曲30°、60°和90°时，患侧内侧和外侧滑车沟的SWE值较高。在主动和被动膝关节伸展时，外侧滑车沟在0°、30°和60°时的SWE值与髌腱下方在0°时以及髌上囊在30°时的SWE值呈负相关。髌上囊在60°时的值与膝关节屈曲和被动膝关节屈曲均呈正相关，而髌上囊在90°时的值与活动范围和被动活动范围均呈正相关。SWE是一种可重复且有效的检测膝关节瘢痕强度的方法。
