To investigate the surgical method and short-term effectiveness of arthroscopy edge-to-edge #-shaped suture in the treatment of the complete radial tear of the lateral meniscus body.
The clinical data of 13 patients with complete radial tear of lateral meniscus body between May 2020 and August 2023 were retrospectively analyzed. There were 10 males and 3 females, aged 15-38 years (mean, 24.2 years). There were 11 cases of acute injury and 2 cases of chronic injury, with time from injury to admission ranging from 2 days to 5 months. All patients had tenderness in the lateral joint space, and 2 patients with chronic injury had positive McMurray's sign. All patients were treated with arthroscopic edge-to-edge #-shaped suture technique. The knee joint activity and tenderness in the lateral joint space were detected, and the healing of the incision and the occurrence of complications were observed. X-ray films and MRI of the knee joint were performed to evaluate joint degeneration and meniscus healing. Lysholm score, International Knee Documentation Committee (IKDC) subjective score, Tegner score, and visual analogue scale (VAS) score were used to evaluate the functional recovery before and after operation.
The operation time ranged from 46 to 100 minutes (mean, 80.08 minutes). All the incisions healed by first intention, and no complication such as intraoperative vascular and nerve injury or postoperative infection occurred. All 13 patients were followed up 20-59 months (mean, 29.3 months). All patients had no limitation of knee extension and flexion. One patient with chronic injury continued to have tenderness in the lateral space of the knee joint, while the remaining patients had no tenderness, swelling, and locking in the lateral space. Immediate postoperative MRI of knee joint showed continuous recovery of the lateral meniscus. At last follow-up, no degenerative changes were observed in X-ray films of knee joint. Except for 1 patient with chronic injury, the MRI of the other patients showed the healing performance after lateral meniscus suture. Lysholm score, IKDC subjective score, Tegner score, and VAS score all significantly improved when compared with those before operation (<0.05).
The edge-to-edge #-shaped suture technique can effectively repair the complete radial tear of the lateral meniscus body, and the short-term effectiveness is satisfactory.
探讨关节镜下半月板体部全层放射状撕裂的边对边“#”形缝合手术方法及短期疗效。
回顾性分析2020年5月至2023年8月间13例半月板体部全层放射状撕裂患者的临床资料。其中男性10例，女性3例，年龄15 - 38岁（平均24.2岁）。急性损伤11例，慢性损伤2例，伤后至入院时间2天至5个月。所有患者均有外侧关节间隙压痛，2例慢性损伤患者麦氏征阳性。所有患者均采用关节镜下半月板边对边“#”形缝合技术治疗。检测膝关节活动度及外侧关节间隙压痛情况，观察切口愈合及并发症发生情况。术前行膝关节X线片及磁共振成像（MRI）检查，评估关节退变及半月板愈合情况。采用Lysholm评分、国际膝关节文献委员会（IKDC）主观评分、Tegner评分及视觉模拟评分（VAS）对手术前后功能恢复情况进行评估。
手术时间46 - 100分钟（平均80.08分钟）。所有切口均一期愈合，未发生术中血管神经损伤及术后感染等并发症。13例患者均获随访，随访时间20 - 59个月（平均29.3个月）。所有患者膝关节屈伸无受限。1例慢性损伤患者外侧膝关节间隙仍有压痛，其余患者外侧关节间隙无压痛、肿胀及交锁。术后即刻膝关节MRI显示外侧半月板连续性恢复。末次随访时，膝关节X线片未见退变改变。除1例慢性损伤患者外，其余患者MRI显示外侧半月板缝合后愈合表现。与术前比较，Lysholm评分、IKDC主观评分、Tegner评分及VAS评分均显著改善（P<0.05）。
半月板边对边“#”形缝合技术能有效修复半月板体部全层放射状撕裂，短期疗效满意。
