Abstract

The goal of this study is to evaluate both functional and radiological outcomes in patellar fractures management with both techniques; cannulated screws with tension band and modified tension band wiring. 30 patients, with displaced or mildly comminuted and partial articular patellar fractures, were randomly grouped into two groups, 15 in each group. Group 1: fixed by cannulated screws with tension band and group 2: fixed by modified tension band wiring. By comparison between types of fixation, regarding post-operative complication (loss of knee motion, loss of reduction, delayed or non-union and pain during movement) there was no statistically significant difference between types of fixation, but there was statistically significant increase hardware removal and infection in K-wires method. Cannulated screws with tension band has a better radiological outcomes and better curative effects on patella fracture with low incidence of complications. Modified tension band wiring technique despite being the traditional and most widely accepted method of transverse patella fracture fixation; it has certain distinct disadvantages.
