Objective To study the method and effect of the vascularized fibular combined with iliac grafting after the tumor extensive resection for giant cell tumor of the bone around the knee. Methods Twenty-five patients with giantcell tumor of the bone around the knee were reviewed, who had been admitted to our hospital from October 1996 to November 2002, including 17 patients undergoing the fibular and iliac transplantation with the vessels anastomosed afterthe extensive excision of the bone tumor. By the surgicallystaged manner of Enneking, all the patients were grouped in the stage of ⅠA; by the Campanicci’s radioactive image staging, 11 patients were grouped in stage Ⅰ, 5 in stage Ⅱ, and 1 in stage Ⅲ; by the Jaffe’s pathological staging, 9 patients were grouped in stage Ⅰ, 7 in stage Ⅱ, and 1 in stage Ⅲ. Of the patients, 9 were treated by the vascularized fibular combined with iliac grafting in the proximal tibia after the tumor extensive resection, and 8 were treated by the distal femur reconstruction by the operation. The following items were also analyzed: postoperativeinfection, growth of the bone graft, rate of local recurrence, tumor metastasis, and bone death. The function of the knee joint was evaluated. Results According the follow-up of the 17 patients for 26-87 months (mean, 54 months), all thebone graft healed well within 75-120 days (mean, 93 days) after operation. Twopatients had a local recurrence and 3 had a mildly-narrowed joint. The flexion and extension function of the knee joint recovered, with a range of motion of thereconstructed distal femur of 80°-105° (mean, 96°) while the proximal tibia had a range of motion of 90-120° (mean, 110°). The functional outcome wasexcellent in 11 patients, good in 3 patients, fair in 1 patient, and bad in 2 patients,with a total satisfactory rate of 82.4%. Conclusion The vascularized fibular combined with iliac grafting after the tumor extensive resection to treat giant cell tumor of the bone around the knee has advantages of complete resection of the tumor and well-restored or reconstructed structure and function of the knee joint.
