Background
Primary tumors of bone are relatively uncommon,
but a significant proportion of cases arise around the knee.
It is likely that the distal femur and proximal tibia and fibula are common sites of bone tumor location because they are highly vascularized areas,
with very active physes.
The patella,
however,
is only rarely affected.
Bone tumors around the knee occur in those ages when the skeleton is in growth phase and especially in a range between 5 and 20 years,
with the exception of the giant cell tumor and chondrosarcoma which most commonly affect adults.
The clinical presentation can involve pain and swelling,
sometimes associated with a palpable mass.
Benign bone tumors often are asymptomatic and discovered incidentally during a radiological examination for other reason.
