Chondroblastoma is a benign (non-cancerous) tumor that grows at the end of the long bones, close to the joints. They’re most commonly found in the thigh bone, upper arm bone or shin bone, but the vast majority of these tumors develop and occur around the knee. Although they are non-cancerous, they can still cause problems and can grow into healthy bones, so should be treated. Causes

The cause of chondroblastoma is unknown.



The common signs and symptoms of chondroblastoma are:

  • Swelling

  • Joint stiffness

  • Limping

  • Decreased range of motion

  • Ongoing pain in the affected area



To determine if your child has chondroblastoma, your specialized doctor may use multiple tests:

  • Physical exam

  • Imaging tests such as X-rays, MRIs, CT scan or bone scan

  • Biopsy or tissue sample



Our doctors will determine the best course of treatment based on your child’s age, overall health, location of the tumor and other factors. Your child’s doctor will discuss all options for the best outcome for your child.

Surgical Treatment

Chondroblastoma is usually treated with surgery.
