Current Advancements and Strategies of Biomaterials for Tendon Repair: A Review

Front Biosci (Landmark Ed). 2023 Apr 6;28(4):66. doi: 10.31083/j.fbl2804066.


Tendon is a bundle of tissue comprising of a large number of collagen fibers that connects muscle to bone. However, overuse or trauma may cause degeneration and rupture of the tendon tissues, which imposes an enormous health burden on patients. In addition to autogenous and allogeneic transplantation, which is commonly used in the clinic, the current research on tendon repair is focused on developing an appropriate scaffold via biomaterials and fabrication technology. The development of a scaffold that matches the structure and mechanics of the natural tendon is the key to the success of the repair, so the synergistic optimization of the scaffold fabrication technology and biomaterials has always been a concern of researchers. A series of strategies include the preparation of scaffolds by electrospinning and 3D printing, as well as the application of injectable hydrogels and microspheres, which can be used individually or in combination with cells, growth factors for tendon repair. This review introduces the tendon tissue structure, the repair process, the application of scaffolds, and the current challenges facing biomaterials, and gives an outlook on future research directions. With biomaterials and technology continuing to be developed, we envision that the scaffolds could have an important impact on the application of tendon repair.
