  This is the early results of 20 cases of massive osteoarticular allograft performed for reconstruction of lower limb s after resection of bone tumors. These cases include 7 distal femur and hemiarticular ,6 proximal tibio and hemiarticular, 3 total knee joints and 4 proximal femur with total hip replacement.
