Background

  • Spontaneous reduction occurs in up to 50% of dislocations
    • Suggestive by severely injured knee that is unstable in multiple directions
  • Types
    • Anterior (40%)
    • Posterior (33%)
    • Lateral (18%)
    • Medial (4%)

Management

  1. Reduce immediately
    1. Apply longitudinal traction
    2. Splint in 20 degrees of flexion
  2. Vascular assessment
    1. Assess popliteal and distal pulses
    2. Measure ABIs
    3. Duplex ultrasound
  3. Disposition
    1. Strong distal pulses + ABI >0.9 + normal UTZ = Admit for obs with ortho consult
      1. Otherwise, obtain vascular surgery consult and additonal study (e.g. arteriogram, CTA)
