[Clinical observation of arthroscopic all-inside combined with outside-in "suture loop" repair for meniscus bucket-handle tear].

To investigate the effectiveness of arthroscopic all-inside combined with outside-in "suture loop" repair for meniscus bucket-handle tear (BHT).Between August 2016 and May 2019, 44 case of meniscus BHT were treated with arthroscopic all-inside combined outside-in "suture loop". There were 29 males and 15 females with an average age of 26.6 years (range, 18-42 years). The causes of injury included sports injury in 31 cases, falling injury in 7 cases, and sprain in 6 cases. There were 32 cases of medial meniscus posterior horn tears and 12 cases of lateral meniscus posterior horn tears. The disease duration ranged from 6 weeks to 3 months. Thirty-three cases were complicated with anterior cruciate ligament rupture. All patients had normal lower limb alignment. The preoperative Lysholm score was 42.1±9.1. According to the evaluation criteria of MRI and Barrett et al., the healing of meniscus was evaluated, and the effectiveness was evaluated by Lysholm score.All the 44 patients were followed up 8-36 months with an average of 16.8 months. At last follow-up, according to the evaluation criteria of Barrett et al., 39 cases were clinically healed, 5 cases were not healed, the clinical healing rate was 88.6%; according to MRI evaluation, 32 cases were completely healed, 7 cases were partially healed, and 5 cases were not healed, the total healing rate was 88.6%, and the complete healing rate was 72.7%. Lysholm score was 87.8±4.8, which was significantly different from that before operation ( t=31.060, P=0.000).Arthroscopic all-inside combined with outside-in "suture loop" repair is a reliable and effective method for the meniscus BHT, which can obtain good joint function.观察并探讨关节镜下全内联合外-内“环抱”式缝合法治疗半月板桶柄样撕裂（bucket-handle tear，BHT）的疗效。.2016 年 8 月—2019 年 5 月，采用关节镜下全内联合外-内“环抱”式缝合法治疗 44 例膝关节半月板 BHT 患者，其中男 29 例，女 15 例；年龄 18～42 岁，平均 26.6 岁。致伤原因：运动损伤 31 例，高处坠落伤 7 例，扭伤 6 例。内侧半月板后角损伤 32 例，外侧半月板后角损伤 12 例。病程 6 周～3 个月。合并前交叉韧带断裂 33 例。所有患者下肢力线均正常。患者术前 Lysholm 评分为（42.1±9.1）分。根据术后 MRI 及 Barrett 等的评价标准评估半月板愈合情况，采用 Lysholm 评分评价疗效。.术后 44 例患者均获随访，随访时间 8～36 个月，平均 16.8 个月。末次随访时，根据 Barrett 等的评价标准获临床愈合 39 例、未愈合 5 例，临床愈合率 88.6%；MRI 评估完全愈合 32 例、部分愈合 7 例、未愈合 5 例，总愈合率 88.6%，完全愈合率 72.7%。Lysholm 评分为（87.8±4.8）分，与术前比较差异有统计学意义（ t=31.060， P=0.000）。.关节镜下全内联合外-内“环抱”式缝合法是治疗半月板 BHT 可靠、有效的方法，能获得良好的关节功能。.
