patellar data collection

This retrospective cohort study addresses a critical gap in orthopedic trauma by directly comparing the efficacy of two surgical techniques for patellar fractures—a common yet challenging injury with long-term functional implications. Key Contributions:DCSC Superiority in Complex Fractures: Our findings demonstrate that the dual cannulated screw-cable (DCSC) system significantly outperforms traditional Kirschner wire-cable (KWC) fixation in OTA 34-C2 fractures, achieving 8.9-point higher Lysholm scores at 3 months and 41% lower hardware irritation rates (p < 0.001).Faster Healing & Shorter Operative Time: DCSC reduced radiographic union time by 13% (3.04 vs. 3.50 months) and operative time by 17% (62.9 vs. 76.0 minutes), enhancing clinical efficiency.Practical Implications: DCSC is recommended as first-line treatment for comminuted intra-articular fractures, while KWC remains viable for simpler patterns.Why This Matters: Patellar fractures affect active individuals and carry a 25% long-term disability risk. Traditional KWC fixation, though widely used, is plagued by complications. Our study provides robust evidence supporting DCSC as a biomechanically superior alternative, particularly for complex cases—a finding aligned with recent biomechanical models but previously lacking clinical validation.
