In the period 1984-1991, 33 lower limb reconstructions were performed with an uncemented Kotz modular femur tibia reconstruction (KMFTR) prosthesis after resection of 32 malignant bone tumors and 1 benign giant cell tumors. Tumor localization was proximal femur in 12, distal femur in 17, and proximal tibia in 4. ⋯ In 2 of the 4 patients undergoing combined distal femur and proximal tibia resection, a deep infection developed, and above-knee amputation was performed. One local recurrence occurred after proximal femur resection.
