Abstract
OBJECTIVE: To report the initial results from the use of a new technique for fixation of bone grafts in uncontained tibial bone defects in patients undergoing total knee prosthesis implantation. METHODS: Six patients with severe varus deformity of the knee who, after cuts and ligament balancing had been performed, still presented bone deficiencies that reached the edge of the tibial cut and compromised the implant stability, underwent a new fixation technique. RESULTS: Five of the patients had good-clinical results, with integration of the graft within 12 weeks. One patient presented clinical complications with wound dehiscence and implant exposure, which evolved to the need for implant removal and knee arthrodesis. CONCLUSION: Support osteosynthesis as a graft fixation method is a viable option for treating tibial bone deficiencies. The proposed technique certainly needs further studies for its validation.
