Closed Reduction and High-Strength Sutures for Transverse Patella Fractures: A Retrospective Analysis.

Objective: This study aimed to investigate the clinical efficacy of closed reduction high-strength sutures combined with Nice knots in treating transverse patella fractures. Method: We retrospectively analyzed the clinical data of 28 patients who underwent surgery for transverse patella fractures from January 2019 to January 2020. Twelve cases of the study group were treated with closed reduction high-strength sutures combined with Nice knots, and 16 cases in the control group were treated with tension band wiring. Observations included patellar healing, follow-up knee mobility with Böstman score, Lysholm score, surgical data, postoperative complications, and secondary surgery rate. Result: No statistically significant difference was observed between the two groups in the Patient demographic data, with a mean follow-up of 13.14 ± 1.58 months. There was no delayed healing or deep infection in the two groups. In the control group, 2 cases of internal fixation failure and 1 case of superficial infection were observed. The differences in mean fracture healing time, follow-up Böstman score, Lysholm score and knee mobility between the two groups were not statistically different. However, the differences were statistically significant for the duration of surgery, Incision length, intraoperative bleeding and the secondary surgery rate was lower in the study group. Conclusion: Closed reduction high-strength sutures have good clinical efficacy in treating transverse patella fractures, with the advantages of shorter duration of surgery and Incision length,less intraoperative bleeding and no secondary removal.
