Background: Several viable options have been discussed in the literature for management of bone defects that result from resection of proximal tibial sarcomas. Pedicled vascularized fibular graft alone as a reconstructive technique can be considered as an alternative method that needs to be evaluated regarding adequacy, safety, and applicability for these situations. Methods: This is a retrospective case series study of 23 patients (14 male and nine female) aged from 7 yr to 40 yr with proximal tibial sarcomas that were managed from 1999 through 2017 by a knee-sparing limb salvage technique. Routine clinical and radiographic examinations were performed with histopathologic diagnosis that found 16 patients who had conventional osteosarcoma, three patients who had parosteal osteosarcoma, three patients who had Ewing sarcoma, and one patient who had fibrosarcoma. One patient had initial lung metastasis. Results: The average functional score from the revised Musculoskeletal Tumor Society rating scale (MSTS) was 26 (86.6%). Local recurrence occurred in two patients who were managed by amputation. Overall survival in our study was 91.4% with mortality of two patients. Conclusions: Pedicled vascularized fibular graft alone as a novel reconstructive technique after knee-sparing limb salvage surgery for juxtaarticular proximal tibial sarcoma is an effective technique with overall good oncologic and functional results. Level of Evidence: Level IV
