Quickly evolutive skin necrosis and deep infection after total knee arthroplasty (TKA) are not uncommon. Several predisposing factors, such as immunosuppression, malnutrition, steroid use, rheumatoid arthritis, multiple scars, and vascular disease can be involved in the onset of wound complications, as well as long tourniquet time and early knee flexion. Skin necrosis after TKA can be treated in different ways, including local wound care, debridement, and soft tissue coverage with muscle or skin grafts. This article presents a rare case of skin necrosis occurring in a patient without any other apparent risk factor after TKA. A 78-year-old woman affected by primary osteoarthritis of the right knee who had no comorbidities and who had already undergone TKA for primary osteoarthritis on the left knee underwent a cemented TKA. Three days postoperatively, she developed a fever and wound problems, which soon after turned into skin necrosis. This complication was first treated surgically with a debridement of the wound with antibiotic therapy and local wound care, then with vacuum-assisted closure (Kinetic Concepts Inc, San Antonio, Texas) therapy and soft tissue coverage using skin grafting. She had a complete recovery in the next 3 months; the skin grafting was well tolerated and the range of motion and functional outcome were good.

Abstract
Quickly evolutive skin necrosis and deep infection after total knee arthroplasty (TKA) are not uncommon. Several predisposing factors, such as immunosuppression, malnutrition, steroid use, rheumatoid arthritis, multiple scars, and vascular disease can be involved in the onset of wound complications, as well as long tourniquet time and early knee flexion. Skin necrosis after TKA can be treated in different ways, including local wound care, debridement, and soft tissue coverage with muscle or skin grafts. This article presents a rare case of skin necrosis occurring in a patient without any other apparent risk factor after TKA. A 78-year-old woman affected by primary osteoarthritis of the right knee who had no comorbidities and who had already undergone TKA for primary osteoarthritis on the left knee underwent a cemented TKA. Three days postoperatively, she developed a fever and wound problems, which soon after turned into skin necrosis. This complication was first treated surgically with a debridement of the wound with antibiotic therapy and local wound care, then with vacuum-assisted closure (Kinetic Concepts Inc, San Antonio, Texas) therapy and soft tissue coverage using skin grafting. She had a complete recovery in the next 3 months; the skin grafting was well tolerated and the range of motion and functional outcome were good.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
