Fractures de la patella : aspects épidémiologiques, anatomocliniques et thérapeutiques

Abstract

Introduction: Patella fractures are uncommon. Treatment is most often surgical. The aim was to describe the epidemiological, anatomical-clinical and therapeutic aspects.
Methods: This was a retrospective study conducted in the department from January 2011 to December 2018. It included all patients (>15 years) treated for patella fracture. The variables studied were epidemiological, anatomical-clinical and therapeutic.
Results: There were 39 fractures. The frequency was 1.6%. The mean age was 39 years (16-77). The sex ratio of men to women was 2.9. Road traffic accidents were the predominant aetiology (n=30; 77%). Fractures were open (n=22; 56%) and type I according to Ricard and Moulay represented 77% (n=30). Treatment was orthopaedic (n=1;3%) and surgical (n=38;97%). Brace fixation accounted for 94% (n=37). The average time to consolidation was 64 days (21-154). Complications observed were skin necrosis (n=1), knee stiffness (n=7) and pseudoarthrosis (n=1). At a mean follow-up of 34 months (13-60), 22 patients were reviewed. The functional outcome was excellent (n=5;23%), good (n=12;54%), and poor (n=5;23%).
Conclusion: Patella fractures accounted for 1.6%. Young adult males were most affected. Skin opening was common in relation to surgical treatment. The overall functional results were satisfactory
