摘  要:目的对比膝关节骨性关节炎患者与正常对照组在不同摄影体位下的膝关节间隙,探讨病例组在不同摄影体位下关节间隙与其疼痛VAS评分之间的相关性,以期发现诊断膝关节骨性关节炎的关节间隙测量方法。方法通过采用膝关节正位、负重正位、屈膝60°侧位及屈膝15°侧位等不同体位的X线投照,获取两组膝关节相关数据,将两组数据进行统计学分析;采用划线法得到膝关节骨性关节炎病例组疼痛的VAS评分,将其与所对应的关节间隙数据进行相关性分析。结果膝关节负重正位内、外侧关节间隙、卧位正位内、外侧关节间隙、屈膝60°侧位内侧关节间隙及屈膝15°侧位外侧关节间隙较正常对照组变窄(P<0.01或0.05),其中膝关节负重正位内侧关节间隙与疼痛VAS评分有相关性(r=0.32,P<0.05)。结论膝关节骨性关节炎患者的关节间隙较正常变窄;采用膝关节负重正位X线摄影比传统卧位X线摄影更具临床诊断价值,膝关节负重正位内侧关节间隙更能反映膝关节骨性关节炎的疼痛程度。Objective To compare knee joint clearance under different body positions of photography between the patients with knee osteoarthritis and control group; to explore the relevance between knee joint clearance under different body positions of photography and VAS scoring of osteoarthritis pain, so as to discover measuring method of joint clearance for the diagnosis of knee osteoarthritis. Methods Relevant data of knee joint of two groups were obtained through x-ray photography under different body positions, and used for statistical analysis; VAS score for the pain of knee osteoarthritis pain was obtained through lineation method and used for relevance analysis with corresponding joint clearance data. Results There was statistical difference between osteoarthritis patients and control group in terms of joint clearance(P〈0.01 or 0.05). There was relevance between knee joint clearance at anteroposterior position and VAS score(r=0.32, P〈0.05). Conclusion The patients with knee osteoarthritis had a narrower joint clearance than control group; X-ray photography at anteroposterior position has more value for clinical diagnosis compared with traditional position. The knee joint clearance of inner side at anteroposterior position can better reflect pain degree of knee osteoarthritis.
