When found around the knee, they are at the end of the femur or the top of the tibia (tibia). They are also found at the top of the humerus (upper arm bone). When found at the shoulder of the humerus, they are called Codman tumors. Other locations where they have been documented are the heel, pelvis, and hip.

If the tumors return, the same or similar procedures are performed. Conclusion: Bibliography: “Chondroblastoma, causes and symptoms”.
