Objectives: To compare the results of fixation of patellar fractures by tension band fixation using Kirschner wires versus figure of eight wiring through cannulated screws. Background: Patellar fractures are relatively uncommon injuries which need to be fixed if displacement occurs more than 2 mm. Methods: This was a prospective study compared the results of treatment of 30 patients with transverse patellar fractures by two methods; Group I: including 15 patients treated with tension band wiring by the kirshner wires. Group II: including 15 patients treated by tension band wiring with cannulated screws. The final results were evaluated after 6 months by the modified hospital for special surgery (HSS) knee score. Results: The mean age of patients was 36.40 ± 12.78 versus 38.60 ± 11.75 years in group I and group II respectively. Regarding the modified HSS knee scoring system there were 5 patients (33.3%) had excellent results in group I versus 12 (80%) in group II, 7 (46.7%) good result in group I versus 3, (20%) in group II, 3 patients (20%) had fair result in group I versus no patients in group II. The mean of radiological union at the end of follow up was 8.0 ± 2.27 (range, 6 – 12) weeks in group I and was 7.07 ± 1.03 (range, 6 – 8) weeks. Conclusion: The cannulated screws with tension band wiring was better than Kirschner wire tension band for the treatment of transverse patellar fractures according to the modified HSS score.
