title: Lateral sural cutaneous artery island flap in the treatment of soft tissue defects at the knee.
abstract: This paper describes a flap for covering defects around the knee. Dissections of 20 legs showed that in the majority the lateral sural cutaneous artery branched from the popliteal artery and descended along the posterolateral aspect of the leg together with two venae comitantes and the lateral sural cutaneous nerve. An island flap was designed, pedicled on these vessels and nerve, and was used in 17 patients with defects around the knee, including acute trauma (three cases), soft tissue tumours (three cases), unstable scar or ulcer (seven cases), and chronic osteomyelitis or infected open fractures with tissue loss (four cases). All the flaps survived entirely and possessed normal sensation. Furthermore, it was not necessary to sacrifice the main vessels of the lower leg.
