Fractures Background

fractures background checkFractures of the knee include fractures of the patella, femoral condyles and tibial plateau. Both direct and indirect forces can cause these fractures.

Patella and tibial plateau fractures each account for 1% of all skeletal fractures. Distal femoral condyle fractures account for 4% of all femur fractures.

Fractures around the knee can result in neurovascular compromise or compartment syndrome, with resultant risk of limb loss. Soft-tissue infection or osteomyelitis can occur in compound (open) fractures.

Other complications include nonunion, delayed union, osteoarthritis, avascular necrosis, fat embolism, and thrombophlebitis.

Clinical features of fractures around the knee :
» Pain
» Swelling
» Inability to bear weight
» Knee movement not possible
» Bruising
» Weakened or absent distal pulses

Investigations :
X-rays
» Anterior posterior view
» Lateral view

CT scan :
» Indicated in comminuted fractures.

MRI :
» Indicated if suspecting an associated ligament tear or meniscus injury.

  2. Bandage a soft padding around the knee.
  3. Shift him to a hospital immediately on a stretcher.
  4. Do not let the victim walk.
