The following are the most important diseases or complications that may be contributed to by chondroblastoma:
Musculoskeletal system and connective tissue (M00-M99).
- Restriction of movement due to limitation of joint activity.
- Secondary osteoarthritis (joint wear) – in the case of chondroblastoma close to the joint surface, esp. at the proximal (towards the center of the body) femur (thigh bone) and at the flat foot, in the long-term course (after approx. 7 years)
Psyche – nervous system (F00-F99; G00-G99).
- Depression
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99)
- Chronic pain
Injuries, poisonings, and other consequences of external causes (S00-T98)
- Pathologic fractures (broken bones) – due to the bone tumor, the affected bone loses strength
