Chondroblastoma is a primary bone tumor in children, adolescents and young adults, which accounts for 1% of all bone tumors. Epiphyseal or epiphysometaphyseal localization, this lesion usually develops from secondary ossification centers close to the knee, shoulder and hip. In our work we will report an original of a knee chondroblastoma in a 13-year-old girl with difficulties in surgical decision-making.
