Digital design of a chimeric DGAP flap. In this case, the skin (SB) and bone (OB) perforators arose from the distal DGA, and the SA originated from the proximal DGA. SV, saphenous vein; DGA, descending genicular artery; MFCF, medial femoral condyle flap; OB, osteoarticular branch; SB, skin branch; SF, skin flap; SA, saphenous artery; DSPS, distance between SP-p and S-p
