【摘要】 目的：探讨关节镜下腰穿套管针辅助经骨隧道缝线“8”字复位固定儿童前交叉韧带胫骨止点撕脱骨折的手术方法和疗效。方法：选择2019年3月～2023年3月行关节镜下腰穿套管针辅助经骨隧道缝线“8”字复位固定治疗的前交叉韧带胫骨止点撕脱骨折的儿童病例36例（36膝），术前Meyers-McKeever-Zaricznyj分型Ⅱ型13例、Ⅲ型17例、IV型6例，均为新鲜骨折。术后X线检查骨折复位愈合情况，比较手术前后Lysholm评分及IKDC评分。记录手术相关并发症。结果：术后随访13～25(15.1±3.6)个月，术后3个月X线片示骨折均愈合；术后6个月、末次随诊Lysholm评分、IKDC评分均高于术前（P <0.05），但术后两时间点相比无差异（P> 0.05）；未发生缝线松动、断裂及关节畸形等并发症。结论：关节镜下腰穿套管针辅助经骨隧道缝线“8”字复位固定儿童前交叉韧带胫骨止点撕脱骨折具有创伤小、固定可靠、利于骨折早期愈合、膝关节功能恢复良好等优点，临床效果满意。更多还原

【Abstract】 Objective: To investigate the surgical technique and efficacy of arthroscopic reduction and “8” suture fixation for tibial insertion avulsion fractures of anterior cruciate ligament(ACL) in children assisted by Lumbar puncture needle through bone tunnel. Methods: From March 2019 to March 2023, 36 cases(36 knees) of tibial insertion avulsion fractures of ACL treated with arthroscopic reduction and “8” suture fixation through bone tunnel. Preoperatively, there were 13 cases of type Ⅱ, 17 cases of type Ⅲ, and 6 cases of type IV according to theMeyers-McKeever-Zaricz-yj classification, all of which were fresh fractures.Postoperative X-ray examinations were conducted to assess fracture reduction and healing. Lysholm and IKDC scores were compared between preoperation and postoperation. Surgical-related complications were recorded. Results: Postoperative follow-up was conducted for 13 to 25(15.1±3.6) months. Radiographs at three months postoperatively showed complete fractures healing.At six months after surgery and at the last follow-up, Lysholm scores and IKDC scores were higher than preoperative respectively(P < 0.05), but there was no significant difference between the two time points(P > 0.05). No complications such as suture loosening, rupture, or joint deformity occurred. Conclusion: Arthroscopic reduction and “8” suture fixation for tibial insertion avulsion fractures of ACL in children assisted by Lumbar puncture needle through bone tunnel can offer advantages such as minimal trauma, reliable fixation, early fracture healing, and good recovery of knee joint function, yielding satisfactory clinical outcomes.更多还原
