Review Question - QID 219489

A 35-year-old male polytrauma patient presents to the trauma bay after a high-speed motor vehicle collision, and his injuries include a closed bicondylar tibial plateau fracture. He is taken to the operating room for an emergent exploratory laparotomy, at which time a knee-spanning external fixator is placed on the right lower extremity. The external fixator remains in place for several weeks before the patient is stabilized and cleared for definitive fixation. Initial placement and the subsequent duration of external fixation stabilization in this patient is associated with an increased risk for which of the following complications after definitive open-reduction and internal fixation?
