The application of electrospinning used in meniscus tissue engineering

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Orthopedics

Background:

• The meniscus, a crucial fibrocartilaginous knee joint component, faces challenges in repair due to common injuries.
• Current treatments like surgery and allografts have limitations, highlighting the need for advanced regenerative strategies.
• Tissue engineering presents a promising avenue for meniscus repair and regeneration.

Purpose of the Study:

• To review the application of electrospinning fibers in meniscus tissue engineering and therapy.
• To explore electrospinning as a method for fabricating materials that mimic native meniscus structure and function.
• To discuss the potential of electrospun scaffolds, substitutes, and patches for meniscus regeneration.

Main Methods:

• Review of existing literature on meniscus structure, injury, and treatment options.
• Analysis of electrospinning techniques for creating fibrous materials with tailored properties.
• Summarization of materials and forms (scaffolds, substitutes, patches) used in electrospun meniscus repair.

Main Results:

• Electrospinning allows fabrication of fibers with tunable mechanical properties, porosity, and orientation, mimicking native meniscus.
• Various materials can be electrospun into forms suitable for meniscus regeneration, including scaffolds, substitutes, and patches.
• Electrospun fibers can be functionalized to carry drugs and provide essential mechanical support for tissue repair.

Conclusions:

• Electrospinning is a viable technique for developing advanced materials for meniscus tissue engineering.
• These engineered materials hold significant potential for meniscus regeneration and therapeutic applications in knee joint repair.
• Further research into electrospun fiber applications could lead to improved treatments for meniscus injuries.
