AB  - OBJECTIVE: Arterial injury in knee trauma is rare but can be devastating if the 
      diagnosis is delayed. The frequency of concomitant arterial injury resulting from 
      knee dislocations remains unclear, and from knee fractures it remains unknown. 
      The primary aim was to investigate the incidence of arterial injury in knee 
      trauma requiring hospitalisation. Secondary aims were to identify risk factors 
      and describe outcome. METHODS: Traumatic popliteal artery injury and knee trauma 
      were identified by International Classification of Diseases (ICD)-10 codes from 
      the Swedish National Inpatient registry (NPR), 1998-2014 and linked with data 
      using the unique personal identification number with the National Registry for 
      vascular surgery (Swedvasc). Risk factors for popliteal artery injury (PAI) such 
      as cause of injury, comorbidities and injury severity were extracted from the 
      NPR. Socio-economic status data and population count came from Statistics Sweden, 
      and cause and date of death from the Swedish Cause of Death Registry. RESULTS: A 
      total of 71 149 admissions due to all knee trauma were identified, and 359 with 
      simultaneous PAIs. Some of those injuries were non-orthopaedic. The proportion of 
      PAI after knee dislocation ranged between 3.4% (46/1370 dislocations or 
      multiligamentous injuries) and 8.2% (46/564 dislocations), and 0.2% after 
      fracture close to the knee (60/36 483). The most common causes of injury with PAI 
      were falls causing knee dislocations and motor vehicle accidents (MVAs) causing 
      fractures. The fact that all 46 injuries occurring after multiligamentous 
      injuries were classified as knee dislocations is probably explained by the fact 
      that the ICD codes are chosen retrospectively when the patient leaves the 
      hospital. CONCLUSION: PAI after knee dislocation is not uncommon, and most 
      frequently caused by a fall. PAI associated with knee fracture is rare and mostly 
      caused by a MVA, while in low energy knee fractures PAI is practically 
      non-existent.
