Clinical Scenario
A 52-year-old motorcyclist presents following a high-speed collision. His right knee is swollen and deformed with a large hemarthrosis. He is unable to weight bear and describes severe pain. On examination, there is tense swelling around the knee, bruising, and valgus instability. The leg compartments feel tense. Distal pulses are palpable but the common peroneal nerve territory shows decreased sensation.

Exam Day Cheat Sheet
Must Mention
- •Schatzker classification: I-VI (VI = bicondylar with metaphyseal dissociation)
- •Compartment syndrome risk: 10-17% with high-energy
- •CT essential for surgical planning (coronal fractures, posteromedial fragment)
- •Staged approach: ex-fix → wait for wrinkle test → ORIF
- •Dual plating: anterolateral + posteromedial for bicondylar
- •Post-traumatic OA: 20-40% at 10 years
Common Pitfalls
- •Operating before wrinkle test positive
- •Missing compartment syndrome (check compartments!)
- •Forgetting posteromedial fragment (60% of bicondylar)
- •Single approach for bicondylar fracture
- •Inadequate bone grafting under elevated articular surface
- •Not documenting peroneal nerve function preoperatively
