Loss of reduction after treatment using a modified anterior tension band wiring in patients with patellar fractures AO type C1

Abstract

Twenty-one patients with AO type C1 patella fractures were treated using modified tension band wire fixation. Loss of reduction before healing was noted in two cases. This early complication was occurred in elderly patients, distal segment of patella complex without displacement. It is difficult to insert the K-wire under fluoroscopic AP view. Therefore, it is necessary to use self-locking pin or other augmentation for fractures involved these risk factors.
