Background: For the common transverse patella fractures, many stabilization techniques have been applied. The high frequency of complications underlines a problem that declares the need for a better fixation technique. This study describes a new technique using a percutaneous, or mini-invasive, cannulated crossing screws to solve this problem.
Material and Methods: Thirty-six patients with displaced transverse patellar fractures were managed with this technique. Their outcomes were evaluated clinically, radiologically, and functionally.
Results: The mean follow-up period was 22 ± 4.31 months. All the fracture united in a mean time of 7.6 ± 1.28 weeks. The average knee flexion was 134.10 ± 7.61 and 0.5° for extension. The mean Lysholm knee score was 94.5 ± 5.7. No major complications, cosmetic, or hardware problem.
Conclusions: The use of crossing screws simplifies fracture fixation, is mini-invasive, and provides stability enough to allow early range of motion exercises, with less injury to the extensor mechanism and better cosmetic scar.
