Highlights

● Distance and position of Kirschner wires influence the stability of tension band wiring.

● Kirschner wire guiding device can improve the accuracy of Kirschner wire placement.

● Designing an optimal guide device is the primary development direction to improve the accuracy of Kirschner wire placement.

Abstract

Tension band wiring has been widely used in patellar fracture internal fixation. However, Kirschner wires (K-wires) insertion is time-consuming, because it requires multiple intraoperative fluoroscopies to adjust the insertion angle, and the accuracy of insertion is not ideal. In this review, we summarize the measurement of patellar anatomical parameters, K-wires placement level, and application of guiding devices, with the focus on improving the accuracy of K-wire insertion from perspectives of K-wire placement and guiding devices. This review hope to provide some inspiration for new guiding devices with auxiliary K-wire placement.
