title: Magnetic resonance imaging of injuries to the ankle joint: can it predict clinical outcome?
abstract: OBJECTIVE
  To predict clinical outcome after ankle sprains on the basis of magnetic resonance (MR) findings.
  
  
  METHODS
  Twenty-nine consecutive patients (mean age 32.9 years, range 13-60 years) were examined clinically and with MR imaging both after trauma and following standardized conservative therapy. Various MR abnormalities were related to a clinical outcome score.
  
  
  RESULTS
  There was a tendency for a better clinical outcome in partial, rather than complete, tears of the anterior talofibular ligament and when there was no fluid within the peroneal tendon sheath at the initial MR examination (P = 0.092 for either abnormality). A number of other MR features did not significantly influence clinical outcome, including the presence of a calcaneofibular ligament lesion and a bone bruise of the talar dome.
  
  
  CONCLUSIONS
  Clinical outcome after ankle sprain cannot consistently be predicted by MR imaging, although MR imaging may be more accurate when the anterior talofibular ligament is only partially torn and there are no signs of injury to the peroneal tendon sheath.
