Repair of the exposed wound of knee joint with superficial sural artery fascia island flap

Objective: To explore the application of lateral superficial sural artery fascia island flap to restore the exposed wound of knee joint.Methods: Six cases of exposed wound of knee joint were repaired using the lateral superficial sural artery fascia island flap.The supplying region was repaired by skin grafting.Results: All the 6 flaps were survived.The follow-up lasted for one to six months,and the appearance and function of the knee joints recovered completely.Conclusions: Repair of the the exposed wound of knee joint with lateral superficial sural artery fascia island flap does not injure the known veins,and reaches good results for primary repair of both the supplying region and the accepting region,which guarantees the function of the acceptor site.It is an ideal procedure.
