Abstract
PURPOSE: Reconstruction of the knee extensor mechanism after the excision of a malignant bone tumor is often difficult, particularly if the tumor is located in the proximal tibia. We developed a novel method to reconstruct the knee extensor mechanism using autologous fasciae, and subsequently evaluated the efficacy of this method. METHODS: We examined the studied reconstruction method, range of motion, extension lag, knee extensor strength, and functional evaluation of three patients with a malignant bone tumor in the proximal tibia. All three patients underwent reconstruction of the knee extensor mechanism by our method. RESULTS: All patients experienced satisfactory outcomes with regard to the above-mentioned parameters. The functional evaluation scores in the three patients were 90%, 95%, and 95% (mean, 90%). CONCLUSION: In this analysis of our recently devised reconstruction method, the follow-up duration was short and only three patients were investigated. However, if appropriate patients are carefully selected for this procedure, long-term outcomes associated with new technique may be better than those associated with other methods of the knee extensor reconstruction.
