Abstract

PURPOSE
The soft tissue injuries of the patellar area are difficult problems because of insufficient arterial blood supply and lack of muscle layer. There have been many methods for reconstructing the soft tissue injuries of the patellar area such as primary closure, skin graft, local flap and free tissue transfer. However, each method has some limitations in their application. After the first introduction, the fasciocutaneous flaps are widely used to reconstruct the soft tissue injuries. The saphenous nerve, one of the superficial sensory nerves in the lower leg, is supplied by the saphenous artery and its vascular network. We used the saphenous fasciocutaneous island flap to reconstruct the soft tissue injuries of the patellar area. METHODS: From March 2002 to May 2005, we used the saphenous fasciocutaneous island flap to reconstruct the soft tissue injuries of the patellar area. The flap was elevated with saphenous nerve, saphenous vein and saphenous artery and its vascular network. The flap donor site was reconstructed with primary closure or split-thickness skin graft.
RESULTS
Five cases survived completely but 1 case developed partial necrosis of the skin on the upper margin of the flap. However, the necrosis was localized on skin layer, and we reconstructed with debridement and split-thickness skin graft only. After the operation, there was no contracture or gait disturbance in any patient.
CONCLUSION
In conclusion, the saphenous fasciocutaneous island flap is safe, comfortable and effective method to reconstruct the soft tissue injuries of the patellar area.
