Total replacement of the knee and of a long segment of the femur or
tibia provided functional recovery of the knee joint in thirteen patients
in whom the length of the bone replaced ranged from seventy-five to 150
millimeters. Nine patients had benign bone tumors, three had malignant
lesions, and one patient had salvage of a failed total knee arthroplasty,
associated with loss of bone structure. After follow-up of two years or
more, all patients had a stable extremity, excellent relief of pain, and a
useful range of motion, although one patient required revision for
loosening.
