Long-term Results of Osteoarticular Allograft Reconstruction in Children with Distal Femoral Bone Tumors

Background: There is no consensus regarding the best method of reconstruction in pediatric population following thewide resection of malignant bone tumors. More exploration of the complications of osteoarticular reconstruction leads toless existing controversy of this type of reconstruction, which is the main point of this article.Methods: Long-term outcomes and complications of osteoarticular allograft reconstruction of primary distal femoral bonesarcomas in 22 children with mean age of 10.7 years old were reviewed in this study. Musculoskeletal Tumor Society(MSTS) scoring system was used for functional evaluation of the allografts.Results: With an average follow-up time of 81 months, the outcomes of 16 patients with allografts at the final follow upwere evaluated. As expected, Limb length discrepancy (LLD) was observed in all patients (mean LLD= 2.73cm), whichwas significantly correlated to allograft survival time (P
