BACKGROUND Arthroscopic surgery procedures vary depending on the types of meniscus tear, including meniscectomy and meniscus repair. Among the several types of meniscus tear, the horizontal tear of the lateral meniscus at the popliteal hiatus region is a common injury, and its surgical treatment is still inconsistent. METHODS Between January 2018 and October 2018, 20 patients who underwent all-inside repair with suture hook for the horizontal tear of the lateral meniscus at the popliteal hiatus region were recruited. Any operative complication was recorded, and postoperative MRI scans were conducted at the 6 months. The clinical results were graded based on the scale of the Lysholm knee score preoperatively and at follow-up. RESULTS No operative complications were recorded. Postoperative MRIs at the 6 months showed that there was no re-tear for all patients, though signal intensity remained high in T2-weighted MRI in the lateral meniscus for nine cases. The average preoperative Lysholm knee score was 58.6 ± 10.1, which increased significantly to 89.3 ± 7.8 (t = - 11.01, p = 0.001) at the last follow-up. Recurrence or aggravation of symptoms was not noted at the final follow-up. CONCLUSION All-inside repair with suture hook may be a good option for the horizontal tear of the lateral meniscus at the popliteal hiatus region which preserves the meniscus; avoids iatrogenic injury on the adjacent popliteal tendon, common peroneal nerve, and inferior lateral geniculate artery.

关节镜全向内修复带缝合钩，用于pop裂区外侧半月板的水平撕裂：初步报告。

背景技术关节镜手术程序根据半月板撕裂的类型而变化，包括半月板切除术和半月板修复。在几种类型的半月板撕裂中，hi部裂孔区外侧半月板的水平撕裂是常见的损伤，并且其手术治疗仍然不一致。方法收集2018年1月至2018年10月在20裂区外侧半月板水平撕裂用缝合钩进行全内翻修复的20例患者。记录任何手术并发症，并在6个月时进行术后MRI扫描。术前和随访时根据Lysholm膝关节评分的等级对临床结果进行分级。结果未发现手术并发症。6个月后的MRI显示，尽管9例外侧半月板的T2加权MRI信号强度仍然很高，但所有患者均没有再次撕裂。术前Lysholm膝关节的平均评分为58.6±10.1，在最后一次随访时显着提高至89.3±7.8（t =-11.01，p = 0.001）。在最后的随访中未发现症状的复发或加重。结论用缝线钩进行全内侧修复可能是pop半月板外侧半月板水平撕裂的最佳选择，以保留半月板。避免对邻近的pop肌腱，腓总神经和下外侧膝状动脉进行医源性损伤。术前Lysholm膝关节的平均评分为58.6±10.1，在最后一次随访时显着提高至89.3±7.8（t =-11.01，p = 0.001）。在最后的随访中未发现症状的复发或加重。结论用缝合线钩进行全内侧修复可能是pop半月板外侧半月板水平撕裂并保留半月板的良好选​​择。避免对邻近的pop肌腱，腓总神经和下外侧膝状动脉进行医源性损伤。术前Lysholm膝关节的平均评分为58.6±10.1，在最后一次随访时显着提高至89.3±7.8（t =-11.01，p = 0.001）。在最后的随访中未发现症状的复发或加重。结论用缝线钩进行全内侧修复可能是pop半月板外侧半月板水平撕裂的最佳选择，以保留半月板。避免对邻近的pop肌腱，腓总神经和下外侧膝状动脉进行医源性损伤。结论用缝线钩进行全内侧修复可能是pop半月板外侧半月板水平撕裂的最佳选择，以保留半月板。避免对邻近的pop肌腱，腓总神经和下外侧膝状动脉进行医源性损伤。结论用缝线钩进行全内侧修复可能是pop半月板外侧半月板水平撕裂的最佳选择，以保留半月板。避免对邻近的pop肌腱，腓总神经和下外侧膝状动脉进行医源性损伤。
