Objective: To review the research progress of the skin flap, fascial flap, muscle flap, and myocutaneous flap for repairing soft tissue defects around the knee so as to provide information for clinical application.
Methods: Domestic and abroad literature concerning the methods of soft tissue repair around the knee in recent years was reviewed extensively and analyzed.
Results: Fascial flaps meet the requirements of thin, pliable, and tough skin in the soft tissue repair around the knee. Myocutaneous flaps and muscle flaps have more abundant blood supply and anti-infection function. Free skin flaps are the only option when defects are extensive and local flaps are unavailable.
Conclusion: Suitable flaps should be chosen for soft tissue repair around the knee according to defect position, depth, and extent. Fascial flaps may be selected as the first flaps for defects repair because of excellent aesthetic results and less injury at the donor site.
