我们测试了关节内超声（IAUS）方法是否可以用于评估人体膝关节关节镜下软骨状态。7例接受膝关节关节镜手术的患者被纳入本研究。超声检查采用关节镜手术相同的门静脉。在关节镜控制下，将高频（40-MHz）超声换能器（直径= 1 mm）定向到关节表面所需位置。除超声数据外，还记录了关节镜下的IAUS视频和光学视频。骨科医生根据国际软骨修复学会对软骨损伤进行分类，为与IAUS的比较提供了参考数据。IAUS方法成功地成像了关节表面的不同特征（例如，完整表面、表面颤动和不同深度的病变）。在一些病例中，在IAUS图像中还可见软骨下骨和异常的内部软骨结构。具体来说，使用IAUS，发现1例患者的局部软骨病变比关节镜下估计的更深。该方法为关节软骨病变的定量成像提供了一种新的关节镜方法。IAUS提供了关于软骨完整性和厚度的定量信息，这在常规关节镜检查中是无法获得的。目前的设备已经被食品和药物管理局批准用于血管内使用，并可能转移到关节内使用。IAUS方法的侵入性可能会限制其在临床的广泛应用，但结合关节镜检查，超声评估可能会扩大关节镜手术的诊断潜力。
We tested whether an intra-articular ultrasound (IAUS) method could be used to evaluate cartilage status arthroscopically in human knee joints in vivo. Seven patients undergoing arthroscopic surgery of the knee were enrolled in this study. An ultrasonic examination was conducted using the same portals as in the arthroscopic surgery. A high-frequency (40-MHz) ultrasound transducer (diameter = 1 mm) was directed to the desired location on the articular surface under arthroscopic control. In addition to ultrasound data, an IAUS video and optical video through the arthroscope were recorded. Classification of cartilage injuries according to International Cartilage Repair Society, as conducted by the orthopedic surgeon, provided reference data for comparison with the IAUS. The IAUS method was successful in imaging different characteristics of the articular surfaces (e.g., intact surface, surface fibrillation, and lesions of varying depth). In some cases, also the subchondral bone and abnormal internal cartilage structure were visible in the IAUS images. Specifically, using the IAUS, a local cartilage lesion of 1 patient was found to be deeper than estimated arthroscopically. The IAUS method provided a novel arthroscopic method for quantitative imaging of articular cartilage lesions. The IAUS provided quantitative information about the cartilage integrity and thickness, which are not available in conventional arthroscopy. The present equipment is already approved by the Food and Drug Administration for intravascular use and might be transferred to intra-articular use. The invasiveness of the IAUS method might restrict its wider clinical use but combined with arthroscopy, ultrasonic assessment may enlarge the diagnostic potential of arthroscopic surgery.
