Modified Tension Band Wiring Combined with Anti-Gliding Loop Augmentation Technique for the Treatment of Comminuted Patellar Fracture: Technical Note and Report of Early Results: Technical Note

ABSTRACT

In order to investigate the feasibility of a modified tension band combined with anti-gliding loop augmentation technique for the treatment of comminuted patellar fracture, 21 patients with comminuted patellar fracture were enrolled in this study. After the modified tension band wiring of patellar fracture, a cerclage wire was passed around the patella. Anti-gliding loops were made on the bending sites of Kirshner-wires. A knot was tied using both ends of the anti-gliding loops, and the cerclage wire was tightened using proximal knots. Bone union was achieved at 4.5+/-1.5 months postoperatively without nonunion. The Lysholm score was 87.1+/-2.8, and the range of motion of the knee was 2.1degrees+/-3.4degrees to 132.2degrees+/-6.5degrees at the last follow-up. The modified tension band combined with anti-gliding loop augmentation technique might be considered an alternative modification of modified tension band wiring for the treatment of comminuted patellar fracture.
