Review Question - QID 8186

Figures 5a and 5b are the radiographs of a 24-year-old obese woman who sustained a knee dislocation in a fall. Postreduction radiographs and an angiogram are shown in Figures 5c through 5e. Examination reveals a cold foot with no pedal pulses. After vascular repair and four-compartment fasciotomy is performed by a vascular surgeon, and while the patient is still in the operating room, you are contacted and asked to evaluate the patient. The knee is grossly unstable. What is the most appropriate initial orthopaedic management?
