Introduction
Displaced comminuted patellar fractures always require
operation. The aim is to restore articular congruity and the
extensor mechanism using an internal fixation technique that is
rigid enough to allow for early rehabilitation of the knee joint
. Tension-band wiring techniques, such as modified
anterior tension band (MATB) involving longitudinal Kirschner
wires and stainless steel wires, have been commonly used for
treatment. The basic principle is to convert the anterior tension
forces produced by the extensor mechanism into compression
forces at the articular surface . However, wire breakage and
migration, painful hardware, and loss of fixation are issues which
lead to high reoperation rates because of the need to remove the
internal implants .
