    • An arthroscopic tibial sizer provided with a collapsible loop (for example, a nitinol loop) and a pin indicator located at about the center of the collapsible loop. The collapsible loop is formed of a flexible wire (for example, nitinol wire) and is designed to collapse so that it can be inserted through an arthroscopic portal and into the joint, and then to expand out to its original diameter once inside the joint space, for visual sizing. The collapsible loop may be provided in various diameters (i.e., 14, 17 or 20 mm, for example) to match various implant sizes. The pin indicator indicates the center of the loop and provides identification of the center of the tibial defect.
    • 关节镜胫骨分切器设置有可折叠环(例如,镍钛诺环)和位于可折叠环的中心附近的针指示器。 可折叠环由柔性线(例如,镍钛诺导线)形成并且被设计成塌缩,使得其可以通过关节镜入口插入到关节中,然后一直扩展到其原始直径在关节空间内 ,用于视觉尺寸。 可折叠环可以以各种直径(例如,例如14,17或20mm)提供以匹配各种植入物尺寸。 针脚指示器指示环的中心,并提供胫骨缺损中心的识别。
