A Case of Chondroblastoma in the Medial Condyle of the Femur Treated With an Intra-Articular Approach via the Intercondylar Fossa.

Adequate bone curettage is crucial for treating epiphyseal chondroblastomas. However, achieving adequate curettage while minimizing damage to the articular cartilage is challenging. For lesions at the center of the distal femoral epiphysis, curettage using an intercondylar approach may have better oncological and functional outcomes than the conventional extra-articular approach from the wall of the epiphysis.
