摘要:


文题释义:

弹性超声:即超声弹性成像,是一种新型超声诊断技术,根据不同组织间弹性系数不同,在受到外力压迫后组织发生变形的程度不同,将受压前后回声信号移动幅度的变化转化为实时彩色图像,从而提供组织硬度信息。
膝骨性关节炎:是以膝关节软骨退变、关节边缘周围骨质增生、软骨下骨硬化为特征的膝关节退行性疾病。作为老年人最常见的致残性疾病之一,它会引起膝关节疼痛、活动受限,最终导致患者功能独立性受损和生活质量下降。

背景:已有研究表明膝骨关节炎患者肌肉弹性会发生变化,但目前的研究多关注于肌张力、肌肉力量的评估,对于股四头肌及其肌腱弹性的评估却鲜有报道。
目的:探究膝骨关节炎患者股四头肌及其肌腱弹性模量特征,并分析其与膝关节疼痛、功能的关系,为膝骨关节炎的防治提供一定依据。
方法:采用剪切波弹性超声成像技术测量30例临床确诊为膝骨关节炎的患者(膝骨关节炎组)和28名无膝关节疼痛的志愿者(对照组)股四头肌及其肌腱的弹性模量。使用西安大略和麦克马斯特大学骨关节炎指数量表(WOMAC)评估入组患者膝关节的疼痛和功能。比较两组受试者股四头肌弹性模量的变化,统计学分析股四头肌弹性模量与WOMAC评分的相关性。

结果与结论:①膝骨关节炎组的股直肌、股中间肌、股内侧肌、股外侧肌、股四头肌肌腱的厚度均小于对照组,但仅膝骨关节炎组的股外侧肌弹性模量值明显大于对照组,差异均有显著性意义(P < 0.05)。②选取与对照组有特征性差异的肌肉弹性模量进行相关性分析,膝骨关节炎组的股外侧肌弹性模量值与WOMAC疼痛量表呈低度线性相关(r=0.367,P < 0.05)。在自我报告的疼痛中,膝骨关节炎患者股外侧肌的弹性模量值仅与上下楼时的疼痛程度呈中度线性正相关(r=0.584,P < 0.05)。在自我报告的功能障碍中,膝骨关节炎患者股外侧肌弹性模量值与下楼梯时、从座位上站起来时的功能均呈中度线性相关(r=0.411,P < 0.05;r=0.464,P < 0.05)。③综上,股外侧肌硬度增高是膝骨关节炎患者股四头肌的特征性改变,从而反映出膝关节负荷增加时的疼痛及功能情况,需进一步研究弹性模量对评估膝骨关节炎患者病情、疗效的意义,从而实现精准康复治疗。

Abstract: BACKGROUND: It has been shown that muscle elasticity changes in patients with knee osteoarthritis, but most of the current studies have focused on the assessment of muscle tone and muscle strength. Changes in the elasticity of the quadriceps and its tendons in patients with knee osteoarthritis have rarely been reported.
OBJECTIVE: To investigate the characteristics of the elastic modulus of the quadriceps femoris and its tendons in patients with knee osteoarthritis and to analyze its relationship with knee pain and function, thereby providing some basis for the prevention and treatment of knee osteoarthritis.
METHODS: The elasticity of the quadriceps femoris and its tendons was measured by shear wave elastography in 30 patients with clinically confirmed knee osteoarthritis (knee osteoarthritis group) and 28 healthy individuals without knee pain (control group). The Western Ontario and McMaster University Osteoarthritis Index (WOMAC) was used for knee pain and function assessments in both groups. Changes in the modulus of elasticity of the quadriceps were compared between the two groups. The correlation between the elastic modulus of the quadriceps muscle and the WOMAC score was statistically analyzed.
RESULTS AND CONCLUSION: (1) The thickness of the rectus femoris, middle femoris, medial femoris, lateral femoris and quadriceps tendon was less in the knee osteoarthritis group than in the control group. The elastic modulus of the lateral femoris was significantly higher in the knee osteoarthritis group than in the control group (P < 0.05). (2) The elastic modulus of muscles that was characteristically different from the control group was selected for correlation analysis. The elastic modulus of the lateral femoris in the knee osteoarthritis group showed a low linear correlation with the WOMAC pain scale (r=0.367, P < 0.05). In the self-reported pain scale, the elastic modulus of the lateral femoris in patients with knee osteoarthritis was only moderately linearly positively correlated with pain level during going up/downstairs (r=0.584, P < 0.05). In the self-reported functional impairments scale, patients with knee osteoarthritis showed a moderate linear correlation between the elastic modulus of the lateral femoris and the function when going downstairs and getting up from a seat (r=0.411, P < 0.05; r=0.464, P < 0.05). (3) From the above, an increased stiffness of the lateral femoris may be a characteristic change in the quadriceps muscle of patients with knee osteoarthritis. This in turn reflects the pain and function of the knee joint during increased loading. Further research is needed to investigate the significance of the modulus of elasticity in assessing the condition and outcome of patients with knee osteoarthritis, so as to achieve the precise rehabilitation treatment.
