Case Of the Week (COW) 28 June 2015
Pellegrini-Stieda lesion
Findings
Focal ossification noted at medial collateral ligament attachment site
Discussion
Pellegrini-Stieda (PS) lesions are ossified post-traumatic lesions at (or near) the medial femoral collateral ligament adjacent to the margin of the medial femoral condyle. One presumed mechanism of injury is a Stieda fracture (avulsion injury of the medial collateral ligament at the medial femoral condyle). Plain film shows Calcification adjacent to the medial femoral condyle, often linear in shape.
