title: Osteochondritis dissecans of the knee: sonographically guided percutaneous drilling.
abstract: OBJECTIVE
  The purpose of this study was to present a procedure for sonographically guided percutaneous drilling in the treatment of a case of osteochondritis dissecans (OD) of the knee.
  
  
  METHODS
  A 14-year-old boy had OD of the external femoral condyle. Conventional radiography, magnetic resonance imaging, and sonography revealed the osteochondral lesion.
  
  
  RESULTS
  This study showed the utility of sonography both in the treatment of OD through percutaneous drilling and in follow-up.
  
  
  CONCLUSIONS
  On the basis of the good results obtained in the case described here, it is thought that sonographically guided percutaneous drilling may be a good alternative to arthroscopic drilling in cases of early OD lesions without displacement of the fragment.
