Comparative Analysis of Two Different Fixation Methods for Treatment of the Intercondylar Eminence Fractures of Tibia

［Abstract］Objective To compare the effect of hollow screw and double suture anchors for the treatment of the intercondylar eminence fractures of tibia. Methods The data of 68 patients with intercondylar eminence fractures of tibia from January 2006 to January 2012 were retrospectively reviewed. 33 patients of them received treatment of hollow screw，35 patients received double suture anchors. All patients had X-ray films before operation. After follow-up of 3，6，12 and 36 months， they all were examined by X-ray eminence in an appropriate position. Union time was from 6 to 12 weeks and evaluated by Lysholm system. Results After a follow-up for 24 to 43 months and the average period was 36 months. A total of 68 patients turned up. The outcome of treatment was evaluated on the basis of X-ray and clinical findings in hollow screw group and double suture anchors group. Union and average time was 8 weeks. During the follow-up time， clinical evaluation included the range of motion and knee joint stability was examined and no knee joint instability and abnormal activity were found. During the 3 months and 6 months， there were significant differences between hollow screw group and double suture anchors group（P > 0.05）. But during the follow-up from 12 to 24 months， there were significant differences between hollow screw group and double suture anchors group（P＞0.05）according to Lysholm system，clinical evaluation including range of motion and knee pain was examined and knee pain and abnormal activity were found in this two groups. Conclusion Clinical characteristics of patients and individual requirement should be considered comprehensively before an individual treatment choice is made for the treatment of the intercondylar eminence fractures of tibia.
