Knee dislocations with ligament tears require immediate evaluation for vascular and neurologic damage. Prompt surgical intervention and fasciotomy are crucial for limb salvage and functional recovery in these complex knee injuries.

Area of Science:

  • Orthopedic Surgery
  • Vascular Surgery
  • Trauma Care

Background:

  • Knee dislocations, particularly those involving multiple ligamentous injuries, pose a significant risk of associated neurovascular compromise.
  • Prompt and accurate assessment of vascular status is critical to prevent limb-threatening complications.

Purpose of the Study:

  • To outline an evidence-based approach for the management of knee dislocations with suspected neurovascular injury.
  • To emphasize the importance of timely surgical intervention and rehabilitation strategies.

Main Methods:

  • Clinical evaluation for neurologic and vascular deficits.
  • Immediate reduction and immobilization of the dislocated knee.
  • Surgical exploration of the popliteal artery if pulses are abnormal.

  • Fasciotomy of the lower leg following vascular repair.
  • Delayed reconstruction and aggressive rehabilitation for select patients.

    • Main Results:

    • Early recognition and management of vascular injury significantly improve outcomes.
    • Popliteal artery exploration is indicated in cases of diminished pulses.
    • Fasciotomy is essential to prevent compartment syndrome after vascular repair.
    • Peroneal nerve injury may require long-term management with orthoses or tendon transfers.

    Conclusions:

    • A high index of suspicion for neurovascular injury is paramount in managing knee dislocations with ligamentous tears.
    • A multidisciplinary approach involving orthopedic and vascular surgeons is essential for optimal patient care.
    • Aggressive rehabilitation is recommended for eligible patients to maximize functional recovery.
