两种不同内固定手术对髌骨骨折患者术后膝关节功能恢复的影响.

Objective: To compare the 2 different ways of the effect of Kirschner wire tension band and hollow nail tension band in the treatment of transverse patellar fracture. Methods: 72 patients with patella fracture treated from June 2016 to October 2017 were selected as objects and randomly divided into control group(n=36) and observation group(n=36) according to the procedures of hospitalization. The control group was treated with Kirschner wire tension band internal fixation, and the observation group was treated with treated with hollow nail tension band fixation. Results: Compared to the two groups, the fracture healing time, postoperative complications, maximal knee flexion angle and Bostman patella score in observation group were better than those in control group(P<0.05). Conclusions: Compared with Kirschner wire tension band, hollow nail tension band has the advantages of simple operation, reliable fixation, quick fracture healing, good knee joint function and fewer postoperative complications. It is worthy of clinical application. [ABSTRACT FROM AUTHOR]
