AbstractRepeated soft tissue injuries around the knee represent challenging clinical situations where functional prognosis of the joint is often poor, especially in the presence of total knee arthroplasty (TKA). When gastrocnemius muscle flap techniques have already been used and failed, therapeutic solutions become rare. The authors suggest a regional solution to salvage these cases by the transfer of distally-based vastus lateralis muscle flaps. Four clinical operations of this muscle flap transfer are described, with three around TKA revision and one case of a post-traumatic knee amputation resulting from a compound open knee injury. Technical details of the intervention are presented. In all cases, skin closure was achieved, even if distal marginal necrosis was seen in two cases related to the type of muscle flap vascularisation.Final joint mobility was always poor (45 grades on average). Distally-based vastus lateralis muscle flaps represent a salvage procedure to correct iterative soft tissue defects around the knee that threaten short-term joint function. These muscle flaps do not require microsurgical anastomosis.2010 Elsevier Masson SAS. All rights reserved.
