The field of oncology that specializes in the diagnosis and treatment of primary benign and malignant tumors of the bone. Malignant tumors of the bone can be primary, which is rare or tumors from secondary deposits elsewhere in the body. Osteosarcoma is the most common form of bone tumour and the most common site of occurrence is around the knee joint. Treatments range from amputation to limb salvage surgeries. Amputation involves removal of a part of the limb or sometimes the entire limb leaving the person disabled or disfigured.

This helps in retaining the integrity of the skeletal system and preserving the limb with useful function.
