Meniscus is a fibrocartilaginous organ to redistribute stress and enhance the stability of knee joint. Meniscus injury is common and still a formidable challenge to orthopedic surgeons. Surgical techniques and allograft transplantation were primary approaches to meniscus repair, but with intrinsic limitations in clinical practice. Tissue engineering is the most promising method to repair meniscus at present. Electrospinning is a method to fabricate fibers in small scale. With different materials and parameters, electrospinning materials could have different mechanical properties, porosity, and orientation, which could mimic architectural features and mechanical properties of native meniscus. Therefore, electrospinning materials could be used in meniscus regeneration and curing. This review gave a brief introduction of meniscus structure, injury, treatment and the application of electrospinning fibers in meniscus tissue engineering and curing. Besides that, we summarized materials commonly used in electrospinning to fabricate meniscus scaffolds, and discussed the form of electrospinning fibers used such as scaffold, substitute and patch. Finally, the function of electrospinning fibers, for example, carrying drugs, providing mechanical properties were described. The potential applications of electrospinning fibers in meniscus therapy were proposed.
