Pelllegrini-Stieda lesion
Ossified post-traumatic lesions at the MCL adjacent to the femoral attachment site of the medial femoral condyle.
Mechanism is likely from an avulsion injury that subsequently calcifies after the initial trauma.
Often an incidental finding on plain films.
If symptomatic, refer to ortho as an outpatient
If not symptomatic, no treatment is indicated
