This study evaluates the use of the needle arthroscopy in anatomical reconstruction of the lateral ankle. We hypothesized that the needle arthroscopy would allow anatomical reconstruction to be performed under arthroscopy. Three patients underwent treatment of chronic ankle instability. The comparative procedure was performed in the following four steps: 1) anteromedial articular exploration (medial/lateral gutter/anterior chamber/syndesmosis); 2)creation of the talar tunnel via the anteromedial arthroscopic approach; 3) anterolateral fibular tunneling; and 4) positioning of the graft by the anteromedial arthroscopic approach. For each of these steps, the planned procedure using the needle arthroscope was compared to the standard arthroscope. For each step, the planned procedure using the needle arthroscopy was compared to the standard arthroscope and the act was classified based on level of difficulty: facilitated, similar, complicated and impossible. The exploration of the medial and lateral gutter, the creation of the tunnel of the talus and graft positioning were not accomplished using the needle arthroscope. While the syndesmosis visualization was facilitated by the needle arthroscope in comparison to the standard arthroscope. The anatomical reconstruction of the lateral ankle, using the needle arthroscopy-only approach, was impossible in all three cases, regarding: ankle joint exploration, creation of the tunnel of the talus and graft positioning. The needle arthroscope should not be considered as a "mini arthroscope" but as a new tool with which it is necessary to rethink procedures to take advantage of the benefits of this instrument.

外踝解剖重建中的针关节镜检查：与标准关节镜检查程序平行比较的三例报告

本研究评估了针关节镜在外踝解剖重建中的应用。我们假设针关节镜检查将允许在关节镜检查下进行解剖重建。三名患者接受了慢性踝关节不稳的治疗。比较过程分为以下四个步骤：1）前内侧关节探查（内侧/外侧沟/前房/联合）；2）通过前内侧关节镜入路建立距骨隧道；3) 腓骨前外侧隧道；4) 通过前内侧关节镜入路定位移植物。对于这些步骤中的每一个，将使用针式关节镜的计划程序与标准关节镜进行比较。对于每一步，将使用针关节镜的计划程序与标准关节镜进行比较，并根据难度级别对行为进行分类：方便、相似、复杂和不可能。内侧和外侧沟的探查、距骨隧道的建立和移植物的定位都没有使用针关节镜完成。与标准关节镜相比，针状关节镜促进了联合可视化。对于踝关节探查、距骨隧道的建立和移植物定位，在所有三种情况下都无法使用仅针关节镜检查方法进行外侧踝关节的解剖重建。针状关节镜不应被视为“迷你关节镜”
