Abstract
Reconstruction in the skeletally immature patient following resection of osteosarcoma about the knee is a challenging problem. Salvaging of the limb with allogeneic or prosthetic replacement results in a shortened limb with functional limitations. Arthrodesis yields a stiff and shortened limb. The so-called growing prosthesis has a high complication rate and is still unproven. However, rotationplasty has been successfully used as a reconstructive technique following resection of these types of tumors in the skeletally immature patient. A limb with normal sensation and proprioceptions, adequate range of motion, and without leg-length discrepancies, functional limitations, or painful neuroma is to be expected. Although a prosthesis must be worn, these patients are active and participate in unrestricted physical activity. Cosmetic acceptance has not been a problem and complications are minimal. Thus, rotationplasty requires only a single operation and results in a highly functional limb.
