Although plain radiology is the primary method for assessing joint space width (JSW), it has poor sensitivity to change over time in regards to determining longitudinal progression. We, therefore, developed a new ultrasound (US) measurement method of knee JSW and aimed to provide a monitoring method for the change of JSW in the future.
A multicenter study was promoted by the Professional Committee of Musculoskeletal Ultrasound, the Ultrasound Society, and the Chinese Medical Doctor Association. US study of knee specimens determined the landmarks for ultrasonic measurement of knee JSW. The US of 1,272 participants from 27 centers was performed to discuss the feasibility and possible influencing factors of knee JSW. The landmarks for US measurement of knee JS, the inflection point of medial femoral epicondyle and the proximal end of the tibia, were determined.
The mean knee JSW1 (medial knee JSW) was 8.57±1.95 mm in females and 9.52±2.31 mm in males. The mean knee JSW2 (the near medial knee JSW) was 9.07±2.24 mm in females and 10.17±2.35 mm in males. The JSW values of males were significantly higher than those of females, with a statistical difference. JSW values were negatively correlated with age and body mass index (BMI) to different degrees and positively correlated with height.
The novel US measurement method can be used to measure knee JSW.
尽管普通放射学是评估关节间隙宽度（JSW）的主要方法，但在确定纵向进展方面，其对随时间变化的敏感性较差。因此，我们开发了一种新的膝关节JSW超声（US）测量方法，旨在为未来JSW的变化提供一种监测方法。
由肌肉骨骼超声专业委员会、超声学会和中国医师协会推动开展一项多中心研究。对膝关节标本进行超声研究，确定膝关节JSW超声测量的标志点。对来自27个中心的1272名参与者进行超声检查，以探讨膝关节JSW测量的可行性及可能的影响因素。确定了膝关节JSW超声测量的标志点，即股骨内侧髁的拐点和胫骨近端。
女性膝关节平均JSW1（内侧膝关节JSW）为8.57±1.95mm，男性为9.52±2.31mm。女性膝关节平均JSW2（内侧近端膝关节JSW）为9.07±2.24mm，男性为10.17±2.35mm。男性的JSW值显著高于女性，差异有统计学意义。JSW值与年龄和体重指数（BMI）在不同程度上呈负相关，与身高呈正相关。
这种新的超声测量方法可用于测量膝关节JSW。
