The outside-in technique is widely preferred for anterior horn tears because of its direct access. However, conventional methods require manipulation of multiple instruments in a limited working space. We introduce a specialized needle with a bidirectional groove at its tip, allowing single-handed antegrade and retrograde suture passage. This simplifies the procedure and reduces operative time. The device is also applicable to bucket-handle tears via a hybrid approach that combines all-inside suture passage and outside-in retrieval, achieving fixation comparable with that of the inside-out technique.
由于其直接进入的方式，由外向内技术在治疗前角撕裂时被广泛采用。然而，传统方法需要在有限的工作空间内操作多种器械。我们推出了一种特殊的针，其尖端有双向凹槽，允许单手顺行和逆行缝线通过。这简化了手术过程并减少了手术时间。该装置还可通过一种混合方法应用于桶柄状撕裂，该方法结合了全内缝线通过和由外向内取出，实现了与由内向外技术相当的固定效果。
