    Patellar fractures have an incidence of 14/100,000 in Germany, with tension-band wiring being the gold standard for surgical treatment.

  • 2

    Biomechanical studies indicate that traditional fixation methods can lead to complications such as implant loosening and secondary fracture displacement.

  • 3

    Intramedullary nail systems may reduce soft tissue preparation and improve force transmission compared to traditional fixation methods.

  • 4

    The study tested a novel intramedullary nail implant system against classical tension-band wiring using biomechanical models.

  • 5

    Results from the biomechanical testing will help evaluate the efficacy of the new intramedullary nail implants for treating patellar fractures.
