Postoperative Outcomes of Star Plate Fixation Versus Tension Band Wiring in Displaced Transverse Patella Fractures

Patellar fractures may occur due to either direct trauma or indirect forces, with the mechanism of injury largely dictating the fracture pattern. Hence, the present study was conducted to compare the efficacy of tension band wiring (TBW) and star plate patella among patients with patella fractures.

This prospective study compared TBW and star plate fixation in 40 patients with displaced transverse patellar fractures, divided equally into two groups. Standardized preoperative assessment, surgical protocols, and postoperative rehabilitation were followed, with outcomes assessed clinically and radiologically over six months using the Böstman scoring system.

Both groups showed comparable fracture union rates (100% in TBW vs. 95% in star plate) and mean union times (10.9 vs. 11.9 weeks, p = 0.338). Functional outcomes were similar, with excellent-to-good results in all TBW cases and 90% of star plate cases (p = 0.8116). Complications were slightly higher in the star plate group, including one non-union, more infections, and stiffness.

Both TBW and star plate fixation achieved comparable union rates, union times, and functional outcomes in displaced transverse patellar fractures. However, the star plate group showed a slightly higher complication rate, including one case of non-union.
