In suspected knee dislocation with absent distal pulses, what is the recommended course?

• A. Manually stabilize the knee and assess distal pulses; if pulses are absent, contact medical control for stabilization instructions.
• B. Immediately realign the knee to restore pulse.
• C. Remove the limb to relieve compression.
• D. Apply traction splint to straighten knee.

Answer: (A)

The situation tests recognizing a limb-threatening knee dislocation and the need to protect the leg while arranging definitive care. When a knee dislocation is suspected and distal pulses are absent, the priority is to prevent further injury and preserve any remaining blood flow. The correct approach is to gently stabilize the knee in the position found and immobilize the leg, then rapidly transport while continuing neurovascular checks. If distal pulses are absent, you should not attempt to realign or straighten the knee in the field, because moving the joint can worsen arterial injury, dislodge clots, or cause additional damage to nearby nerves and vessels. Instead, you seek guidance from medical control on stabilization and pursue urgent transport to a facility capable of vascular assessment and possible surgical intervention.

Realigning the knee in the field is not appropriate here because the goal isn’t to “get the pulse back through manipulation” but to minimize further harm and get definitive care. Removing the limb or using a traction splint isn’t indicated for knee dislocations and could cause additional injury.
