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.
