✅ Double-Bundle PCL Reconstruction
- The double-bundle technique aims better to mimic native PCL for improved posterior stability in flexion
- Biomechanical studies show superior knee laxity and kinematics restoration compared to single-bundle
- Potential for excessively restricted residual anteroposterior translation
- No significant differences in clinical, radiological, and survivorship outcomes at ≥10 years follow-up
①. Femoral Tunnels
- Anterior Bundle: Anterior 1/3 of native PCL insertion
Right knee: 1 o'clock, Left knee: 11 o'clock
- Posterior Bundle: Middle to distal 1/3
Right knee: 3 o'clock, Left knee: 9 o'clock
②. Tibial Tunnel
- Placement varies between single and double-bundle techniques
- Avoid anterior placement to prevent injury to the anterior medial meniscal root
