tumors of the knee. Weinberg H. Kenan S. Lewis MM. Hausman MR. Vickery CB. Bloom ND. Plastic & Reconstructive Surgery. [JC:p9s] 92(4):692-8, 1993 Sep. Limb-sparing surgery has proven to be a feasible alternative to amputation for treatment of malignant tumors about the knee. Microvascular surgery and the possibility of providing healthy, stable soft-tissue coverage to the affected limb have expanded the possible role of limb-sparing techniques. Microvascular free flaps were utilized in 26 patients undergoing resection for large malignant tumors of the knee or adjacent to the knee. Patients were then followed for a minimum of 3 years to a maximum of 7 years and evaluated for tumor recurrence and limb function. Survival and disease-free interval were 68 and 77 percent, respectively, in stage II patients and only 50 and 0 percent, respectively, in stage III patients. Function, as determined by the MSTS functional evaluation system, was found to be fair to good in all patients. Microvascular free -tissue transfer has proven to be a valuable adjunct in limb-sparing surgery.
