Risk factors for peroneal nerve injury and recovery in knee dislocation.

Background: Acute knee dislocation is rare but has a high rate of associated neurovascular injuries and potentially limb-threatening complications. These include the substantial morbidity associated with peroneal nerve injury: neuropathic pain, decreased mobility, and considerably reduced function, which not only impairs patient function but complicates treatment.

Questions/purposes: We therefore identified and quantified the risks associated with specific factors for peroneal nerve injury and recovery in patients with knee dislocations.
