To evaluate the functional outcome in bony Posterior Cruciate Ligament (PCL) avulsion fractures treated with open reduction and internal fixation through Mini open technique. The approach is safe, and simple with a slight modification and technical tips.
Material and Methods: Twenty four patients (19 males and 5 females) were included in the study. Fixation was done through a modified mini open technique using 4 mm cannulated cancellous screws. The minimum follow up considered in study was one year. Functional outcome was assessed using clinical examination, Tegner Lysholm knee score and stress radiography.
Results: The mean Tegner Lysholm scores at the time of 1 year follow up was 91.66. The PCL laxity assessed clinically by posterior drawer test on stress radiography was grade I in 3 cases and nil in rest of 21 at 8 weeks follow-up. All the patients had achieved bony union of tibial avulsion fractures at the time of last follow up.
Conclusion: Bony PCL avulsion fractures treated by Mini open technique with open reduction and internal fixation achieved good to excellent results and can prevent significant late onset disability.
