The enhanced stability of ring pin-based tension band wiring in canine transverse patellar fracture models.

Objective: To evaluate the tensile strength and biomechanical properties of the tension band wire technique using a ring pin in a canine patellar transverse fracture model and to compare it with conventional tension band wire techniques.

Methods: The patella with adjacent structures were harvested from 11 adult canine cadavers and osteotomized transversely. The tension band wiring technique with a single Kirschner wire and metal wire was applied to the KM group (n = 7).
