Background

  • Occurs via axial load that drives femoral condyle into tibia
  • ACL and MCL injuries assoc w/ lateral plateau fx
  • PCL and LCL assoc w/ medial plateau fx
  • Compartment syndrome may occur
  • Segond Fracture
    • Avulsion fx of margin of lateral tibial plateau just below joint line
    • Associated w/ tear of ACL and meniscal ligaments

Diagnosis

Imaging

  • AP, lateral, oblique views (internal for lateral plateau, external for medial plateau)
    • AP - line drawn at lateral margin of femur should not have >5mm of tibia beyond it
  • CT or MRI should be considered if plain film negative but high clinical suspicion

Schatzker Classification

  • Schatzker I Lateral split
  • Schatzker II Split with depression
  • Schatzker III Pure lateral depression
  • Schatzker IV Pure medial depression
  • Schatzker V Bicondylar
  • Schatzker VI Split extends to metadiaphysis
Schatzker Classification of Tibial Plateau Fractures

Differential Diagnosis

Knee diagnoses

Acute knee injury

Nontraumatic/Subacute

Distal Leg Fracture Types

Management

  • Knee immobilizer w/ non-weightbearing and ortho referral in 2-7d

Disposition

  • Indications for referral within 48hr:
    • Significant displacement or depression
    • Suspected or documented ligamentous injury
