Background: Operative treatment of displaced patella fracture dates back to Lister in 1877. Nowadays, steel wires remain the material of choice in tension band technique despite complications such as wire breakage, suboptimal placement, or skin impingement. We propose using a high-tensile strength braided tape-shaped polyblend suture (FiberTape®, Arthrex, Naples, Florida, USA) as an alternative that could minimize complications related to steel wires. Method: Between February 2014 and April 2018, 15 patients with displaced patella fractures (three distal pole, five transverse, and seven comminuted fractures) underwent our proposed method. Open fracture reduction was performed to optimize anatomy before figure-of-eight fixation with FiberTape®. An Ethibond-2 suture was also added as cerclage for stability. Postoperatively, an extension brace was given for wound resting, before progressing to mobilization exercises with a hinge-knee brace. At follow-ups, the knee's range-of-motion (ROM), along with bone healing status from radiographs, was assessed. Results: The mean operation time was 84.5 min, and all surgeries were performed or supervised by the same senior surgeon. Eight patients were discharged from follow-up (mean follow-up of 9.9 months) after achieving good ROM and fracture healing. One patient defaulted, and the remaining is still being followed-up. There was no wound complication or knot impingement in all cases. One patient required manipulation under anesthesia due to stiffness, and one experienced malunion due to poor compliance to rehabilitation protocol. Conclusion: Fixation using a high-tensile strength braided suture may be an equally effective method in the management of displaced patella fracture. However, larger sample size is useful to provide a more definitive conclusion. [ABSTRACT FROM AUTHOR] |
