Biomechanical comparison of three tension band wiring techniques for transverse fracture of patella: Kirschner wires, cannulated screws, and ring pins.

All three methods have sufficient stability at a daily activity. TBWCS showed a better failure load compared with TBWKW and TBWRP. TBWRP showed compatible mechanical characteristics with traditional tension band wiring. TBWRP could be an alternative method for TBWKW.
