Treatment of displaced fractures of the patella: Tension band wiring technique with the one-end or both-ends K-wire bending fixation method

Purpose: Tension band wiring technique has been widely used for treating patellar fracture. Conventional techniques are associated with some complications and several modifications have introduced to increase stabilization. The purpose of this study was compare two different fixation techniques, the one-end both-ends Kirschner wire bending methods. Methods: We retrospectively reviewed patient data from 2013 2017, including age, sex, body height, weight, BMI, lesion injury, trauma mechanism, fracture displacement classification, type fixation, healing duration, length follow-up, clinical results complications. surgical outcome assessed using pain score (VAS), Lysholm knee score, joint ROM. Plain radiographs were evaluate radiographic outcomes assess union duration hardware performed statistical analysis these techniques. Results: There no significant differences between groups in terms demographic data, level K-wires, distance or K-wires over patella (all p > 0.05). VAS K-wire migration, flexion degree, ROM, < 0.001) Conclusion: method a lower complication rate better than method. This revised can effectively control both ends thus eliminating possibility migration improving stability.
