Through knee amputation with gastrocnemius musculocutaneous flap. 6 cases of tibial osteosarcoma followed for 3 (1-6) years.

6 cases of proximal tibial osteosarcoma were operated on by through knee amputation using a long dorsal gastrocnemius musculocutaneous flap; the usual anterior flap could not be used because of tumor size and the location of the biopsy tract. The only complication was one wound dehiscence which healed. The stump was of good quality in all patients. At follow-up, the patients walked without walking aids.
