Pellegrini-Stieda lesion

Case contributed by Dr Charlie Chia-Tsong Hsu

Presentation

Presents with medial knee pain and joint swelling. Patient denies recent history of knee trauma.

Patient Data

Gender: Male
X-ray

Anterior-posterior view of the knee shows linear ossification/calcification at the site of proximal medial collateral ligament (MCL) origin. Lateral view demonstrates joint effusion in the suprapatella recess.

Case Discussion

Pellegrini-Stieda lesion is thought to be the result of stripping of the femoral periosteum near the origin of the MCL, which leads to heterotopic ossification and dystrophic calcification.
