Femoral and fibular lesions are present.

The tibial lesion is approximately 6 x 5 cm in size.

Thin cartilage cap in the femoral lesion. Most of the tibial lesion shows a thin cap.

The posterior-medial-cranial part of the tibial lesion shows cartilage cap thickness up to 18 mm.

An excisional biopsy of the tibial lesion was performed due to the risk of malignancy in a thickened cartilaginous cap (>15 mm). However, this was benign on histopathology.
