Abstract:

BACKGROUND: Wound complications probably result in severe soft tissue defects after total knee arthroplasty, which brings orthopedic surgeon a big challenge. Some treatment options, such as frequent sterile dressings changes, persistent drainage, minor or thorough debridement, negative pressure wound therapy and split-thickness skin grafts, fail to help those quite large and deep wounds around the knee, with exposed fascia or prosthesis, bone, joint, tendon, large vessels and nerve, heal by secondary intention. Under these situations, orthopedic surgeon should consult plastic surgery and propose flap re-construction.

OBJECTIVE: To introduce some types of flaps for orthopedic surgeon, so as to help orthopedic surgeon understand and chose flaps logically, and reduce severe consequences caused by soft tissue defect wounds.

METHODS: The first author retrieved databases of PubMed, Medline, Wanfang and CNKI for the articles concerning wounds repaired by flap transfer after total knee arthroplasty published before 2019. The key words were “flap, knee, wound” in Chinese and English, respectively. Initially 668 articles were retrieved and 45 eligible articles were included in accordance with the inclusion and exclusion criteria for analysis.

RESULTS AND CONCLUSION: (1) Flap reconstruction is widely applied in plastic surgery. It is significant for orthopedic surgeon to recognize the characteristics of each flap. (2) Selecting and designing suitable type of flap according to the three-dimensional structure and position of wounds is helpful for repairing soft tissue defect, reducing the risks of prosthesis exposure, periprosthetic infection, prosthesis removal and even amputation after total knee replacement after total knee arthroplasty.

Key words: flap, local flap, muscle flap, myocutaneous flap, free flap, flap reconstruction, total knee arthroplasty, wound, wound complication
