Abstract：Objective To compare the biomechanical properties of 4 constructs of tension band wiring made of 3 different sizes stainless steel-wires. Methods Transverse fractures were simulated in 8 adult cadaver knees and fixed with Kirschner wires in combination with figure-of-8 and parallel wire configurations of 3 different sizes stainless steel-wires. Biomechanical stability were tested by interfragmentary compression and fracture gaps after the knees,1000 cycles of flexion-extension mo-tions. Results Fractures were more stable fixed with Kirschner wires in combination with parallel than figure-of-8 wire config-urations. The interfragmentary compressions were bigger when the fractures fixed with 1. 2 mm diameter wires,but fracture gaps were narrower when the fractures fixed with 1. 0 mm diameter wires. Conclusion Patella fractures can been fixed more stable with tension-band wiring by adjusting size and constucts of stainless steel-wire.
