Abstract

High rates of reduction loss and revision surgeries have been reported with modified tension band wiring (MTBW) in patella fractures. Bilaterally bending the K-wires has been described to prevent these complications. The purpose of the study was to compare loss of reduction and the need for revision surgery when K-wires were bent at both ends or not in patella fractures treated by MTBW. This is a retrospective study including a consecutive series of 179 patients with patella fractures treated by MTBW. 70 patients had a MTBW with K-wires bent at both ends (group 1), and 109 patients had MTBW with K-wires bent at one end or not bent at all (group 2). Reduction loss was 4.3% in group 1 and 25.7% in group 2 (p=0.0002). Revision surgery was needed for 0% of the cases in group 1 and 9.2% in group 2 (p=0.068). Bending the K-wires at both ends significantly decreased the rate of reduction loss and revision surgery.
