Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of polyester sutures with Nice knots for fixation of transverse patella fractures. [Methods] A total of 20 patients underwent non-absorbable polyester sutures with Nice knots for fixation of transverse patellar fractures. After anterior midline incision of the knee was made to expose the patella, the fractures were debrided and reduced, and 4 evenly distributed bone tunnels were established along the longitudinal axis of the patella. The tension band of the suture in figure of 8 was performed on the surface of the patella after the 5 # non-absorbable polyester sutures were introduced through the deeper 2 bone tunnels near articular surface. Finally, a circular band was performed with 5 # non-absorbable polyester sutures through the other superficial 2 bone tunnels. All the suture bundles were tensioned and fastened with Nice knots to fix the fracture. [Results] All the patients had operation performed successfully without serious complications, while with operation time of 50~90 min. At the latest follow up lasted for 12 to 18 months, all of them achieved fracture healing with B?stman patellar fracture function score of (28.3±1.6), and the knee range of motion of (132.3 ± 4.2)°. According to the B?stman patellar fracture function score, all patients were graded as excellent in term of knee function. [Conclusion] Polyester sutures with Nice knots for fixation of transverse patellar fracture has the advantages of reliable fixation, less complications, and no need for reoperation to remove the internal fixation, does achieve satisfactory clinical consequences in short-term.
