Fig. 5From: Where should Kirschner wires be placed when fixing patella fracture with modified tension-band wiring? A finite element analysisa The average von Mises stress of K-wires. Linear with SP (R = − 0.93, P = 0.02). The ends of the whiskers represent the boundaries of outliers, and it is the same in Fig. 5b. b The average von Mises stress of SS-wires. c The stress distribution on the internal fixations. The internal fixations were semi-transparent, including the stress on both anterior and posterior sidesBack to article page
