The lateral genicular artery flap is a fasciocutaneous flap used for knee reconstruction with low donor site morbidity. We performed an anatomical and hystomorphometrical study of the lateral genicular artery flap in eighteen fresh cadavers (thirty-six anatomical regions). Four clinical results of knee reconstruction are demonstrated. We found a constant vascular pedicle (100%), with intramuscular perforators in 40% of dissections. The perforator was situated at 7,40cm ± 2,77 above lateral condylle of the femur, between vastus lateralis muscle and the biceps femoris muscle. The pedicle measured 6,09 ± 1,91 cm of lenght from the popliteal artery. This flap was done and succeded in four patients. This flap showed constant anatomy and is reliable for coverage of defects at superior and lateral portions of the knee and the proximal part of the lower leg.
