Abstract：Objective To explore the effect of minimally invasive internal fixation under knee arthroscopy in treatment of type Ⅰ-Ⅲ tibial plateau fracture.Methods Sixty patients with Ⅰ-Ⅲ tibial plateau fracture treated in our hospital from Jan.2013 to Nov.2015 were selected.There were 44 males and 16 females,with an average of 45.0 years(range,20-70 years old).There were 24 cases of road traffic accident injury,19 cases of falling injury and 17 cases of heavy-objects hitting injury.They were divided into observation group (30 cases) and control group (30 cases) according to random number table method.The observation group was given minimally invasive internal fixation under knee arthroscopy and the control group was given traditional open reduction and internal fixation.The clinical data was compared between the two groups.Results The blood loss and fracture healing time of the observation group was (107.7±12.29)mL,(26.7±1.94) weeks,respectively,which were less than those of the control group((137.8±21.16)mL,(30.7±2.63)weeks,P＜0.05).There was no significant difference in tibial plateau-tibial shaft angle,posterior slope and Rasmussen anatomical scores at 3,6 and 12 months after operations between two groups(P＞0.05).The HSS scores of the observation group were higher than those of the control group at 3,6 and 12 months after operations(P＜0.05).At the last follow-up,there was no significant difference in the operation effect between two groups(P＞0.05).Conclusion As for type Ⅰ-Ⅲ tibial plateau fracture,compared with traditional open reduction and internal fixation,minimally invasive internal fixation under knee arthroscopy has advantages of less damage to the soft tissue and better knee function recovery.
