Operations of malignant bone tumors around knee in young patients

Osteosarcoma is a primary, malignant, bone tumor that occurs in young, growing patients. The most frequently affected parts are the distal femur and proximal tibia. With rising survival rates following chemotherapy, limb salvage surgeries are becoming the standard operational methods for the majority of these patients. This is a challenging situation for surgeons treating patients following epiphysis resection and limb reconstruction with the most suitable procedure in order for the least length discrepancy compared with the ongoing growth of the contralateral limb. In this book, the authors gave a detailed description of some biological constructions, such as physeal distraction, trans-epiphyseal/ metaphyseal section with autologous or allograft replacement in the management of osteosarcoma in growing young patients. The discussion of surgical indications, clinical results of knee joint function, complications of limb discrepancy, delayed union, infection, recurrence and survival rate was also reported.
