To report the experience of limb salvage with different methods for malignant tumors of the knee and discuss their advantages and disadvantages. Methods From January 1990 to March 2002, 63 patients with malignant tumors of the knee underwent limb salvage surgery. After en bloc resection, 28 cases were reconstructed with devitalized original tumor-bearing bone, 22 cases with allograft, and 13 cases with tumor endoprostheses. The local recurrences, complications and knee function of three different surgical methods were compared. Results Although the local recurrences of the three groups were similar (21.4% for the devitalized bone, 18. 2% for the allograft and 15. 4% for tumor endoprotheses), tumor endoprotheses showed less complications and better knee function. Conclusions The present study shows that limb salvage with endoprothesis has less complication and better knee function, however, reconstruction with devitalized tumor-bearing bone and allograft are still simple and useful tool for skeletal immature young patients.
