Figure 3. Definition of the incision point of the superior-edge-of-the-knee incision method. The incision point of the superior-edge-of-the-knee incision method is 2.5 cm posterior from an intersection of transverse line drawn at the upper edge of the patella (black line) and the longitudinal line drawn along the medial axis of the distal thigh (white line) in the supine position. At the specific point of the incision, relatively large, less-sclerotic lymphatic vessels are always detected and utilized for an efficient functional LVA. In addition, the subcutaneous veins with good valvar function can be detected and utilized for the recipient vein of LVA. LVA: Lymphaticovenular anastomosis.
