Bone tumors around the knee

Abstract

Bone tumors are commonly located around the knee, in the distal femur and proximal tibia and less frequently in the proximal fibula and patella. Treatment of bone tumors depends on the histological grade, the size and location of the tumor and the characteristics of the patient. Generally, benign bone tumors are adequately treated by either an intralesional or a marginal resection. To reduce the risk of recurrence, the intralesional resection may be extended with mechanical, chemical, and thermal adjuncts. Primary bone sarcomas and some aggressive benign tumors require a wide resection. Limb salvage principles are largely employed if neurovascular structures can be preserved and a level of function maintained. After tumor resection with a wide margin, the defect left poses a reconstructive challenge. In this chapter, we will refer to bone tumors that most frequently arise around the knee and may affect adult population. First, we consider the basic characteristics of these tumors and then the surgical treatment, focusing in those techniques that preserve the joint.
