Abstract: Objective to investigate the clinical effect of arthroscopic-assisted minimally invasive internal fixation in the treatment of Shatzker Ⅰ-Ⅳ Tibial plateau fracture. Methods The clinical data of 42 cases of tibial plateau fracture were analyzed retrospectively from February 2015 to August 2018 which were divided into observation group and control group， each group 21 cases. The observation group was treated with percutaneous minimally invasive fixation assisted by Arthroscopic techniques. The control group was treated with traditional open operation. The effects were evaluated by Rasmussen Score. Results The follow-up time was 6 to 24 months （10.3 months on average）. After 6 months and 12 months， Rasmussen score was better than that of control group （P<0.05）. In the observation group， the different grades of Rasmussen were better than those of the control group （P<0.05）. Compared with control group and observation group， the superiority rate was 57.1% and 90.5% respectively， the difference was statistically significant （z=3.921， P=0.044）. There were no complications such as infection， osteofascial compartment syndrome and deep vein thrombosis. control group infected 1 case， after treatment of the disease， recovered. There was no statistically significant difference in the incidence of complications between the two groups. Conclusion the treatment of Scharzker Ⅰ-Ⅳ Tibial plateau fracture with percutaneous minimally invasive fixation with arthroscopic technique is less traumatic， less complication and more effective.

摘要： 目的 探讨关节镜辅助下微创内固定治疗SchatzkerⅠ~Ⅳ型胫骨平台骨折的临床疗效。方法 回顾性分析2015年2月至2018年8月广州市中西医结合医院收治的42例胫骨平台骨折患者的临床资料，按术式的不同分为观察组和对照组，每组21例。观察组采用在关节镜技术辅助下经皮微创内固定术治疗；对照组采用传统开放手术进行治疗。按照Rasmussen评分标准进行手术疗效评估。结果 术后随访时间6～24个月（平均10.3个月）。观察组术后6个月，12个月Rasmussen评分优于对照组（P<0.05）；进一步分型比较，观察组Schatzker各分型Rasmussen评分均优于对照组（P<0.05）。对照组、观察组优良率分别为57.1%、90.5%，两组比较，差异有统计学意义（Z=3.921，P=0.044）。观察组未发生感染、骨筋膜室综合征及深静脉血栓形成等并发症；对照组感染1例，经对症处理后痊愈。两组并发症发生率比较，差异无统计学意义。结论 关节镜技术辅助下经皮微创内固定治疗ScharzkerⅠ~Ⅳ胫骨平台骨折创伤小，并发症少，疗效肯定。
