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.
