Introduction

The reconstruction of the knee in growing children considers many options and the chosen solution is often patient (or surgeon) based. Megaprostheses represent a reliable solution but quite expensive in the non-invasive growing version and not free from complications. In an Italian reference center for Bone and Soft tissue sarcomas, following the experience of Rizzoli Institute in Bologna, we performed the reconstruction with a resurfaced allograft for the distal femur or the proximal tibia in selected patients. The aim of the study is to confirm the reliability of this technique and to identify its potential advantages and indications.

Methods

Among 60 children below 16 years old with bone sarcomas (39 osteosarcomas, 21 Ewing's sarcomas, age range 4–16) treated since 2007, 35 cases were around the hip and the knee. 7 pediatric knees (age range 5–12 ys) with the tumor involving the epiphysis were reconstructed using a resurfaced allograft for distal femur (2) or proximal tibia (6) leaving intact the other half of the joint. Functional outcome (MSTS score), complication rate, and oncologic follow up were evaluated.
