Summary: The aim of this study was to introduce various applications of miniplate augmented tension-band wiring (TBW) for comminuted patella fractures and to evaluate the clinical outcomes. Comminuted articular patella fractures were managed with anterior cortical miniplate fixation with a TBW technique from January 2014 to January 2016. The primary end point was radiographic union. Secondary end points were complications related to the procedure. Functional outcomes including range of motion were also evaluated. Thirty patients were followed up for a mean of 20 months (range, 12–28) postoperatively. The primary union rate was 96% (29 of 30 patients). Mean time to union was 3.2 months. One patient required additional surgery because of acute postoperative infection. Twenty-five patients recovered a full range of motion relative to the contralateral limb. The mean Bostman score at the last follow-up was 28.6 points (range, 26–30). In conclusion, miniplate augmented TBW is a versatile and useful technique for comminuted patella fracture fixation.
