Combined turnover vastus lateralis and lateral gastrocnemius flaps as a salvage option for soft tissue reconstruction of the knee

Infection with subsequent wound breakdown and soft tissue deficit represents the most devastating complication after total knee arthroplasty. Although microsurgical reconstruction is increasingly being performed in this setting, several factors may preclude its use. We present a case of a 52-year-old female patient who presented with a complex right anterior knee wound resulting from a complicated clinical course following total knee arthroplasty. Initial reconstructive efforts included coverage with a superiorly based fasciocutaneous thigh flap as well as a medial gastrocnemius flap. Persistence of infection and necrosis of the distal aspect of the fasciocutaneous flap eventually required salvage by means of a vastus lateralis turnover muscle flap augmented by a lateral gastrocnemius muscle flap. The combination of these two fairly straightforward muscle flaps provided stable wound coverage with well-vascularized tissue without the use of sophisticated microsurgical expertise.
