Abstract

OBJECTIVE: For the past 100 years, Pellegrini-Stieda disease has been described as calcification and ossification within the tibial collateral ligament, although these typical radiographic findings are often located more superior than the most proximal extent of the ligament. In this article, we demonstrate four magnetic resonance imaging cases of knee trauma with complete posterior cruciate ligament tear or avulsion, each demonstrating that injury to the medial collateral ligamentous complex can involve significant stripping of the tissue proximal to the medial epicondyle. CONCLUSION: Classic radiographic findings of Pellegrini-Stieda calcifications can be caused by stripping of the femoral periosteum proximal to the femoral attachment of the tibial collateral ligament, which appears to be associated with a complete posterior cruciate ligament injury.
