Involves disruption of ≥2 major knee ligaments; often from high-energy trauma. Common patterns: ACL + PCL ± collateral injuries. Associated with vascular (popliteal artery) and nerve (common peroneal) injuries. Diagnosis: clinical + MRI; check vascular status with ABI, Doppler, CTA. Management: emergent reduction, vascular repair if injured, staged ligament reconstruction.
