Abstract Tendon adhesion formation describes the development of fibrotic tissue between the tendon and its surrounding tissues, which commonly occurs as a reaction to injury or surgery. Its impact on function and quality of life varies from negligible to severely disabling, depending on the affected area and extent of adhesion formed. Thus far, treatment options remain limited with prophylactic anti-inflammatory medications and revision surgeries constituting the only tools within the doctors’ armamentarium - neither of which provides reliable outcomes. In this review, the authors aim to collate the current understanding of the pathophysiological mechanisms underlying tendon adhesion formation, highlighting the significant role ascribed to the inflammatory cascade in accelerating adhesion formation. The bulk of this article will then be dedicated to critically appraising different therapeutic structures like nanoparticles, hydrogels and fibrous membranes fabricated by various cutting-edge technologies for adhesion formation prophylaxis. Emphasis will be placed on the role of the fibrous membranes, their ability to act as drug delivery vehicles as well as the combination with other therapeutic structures (e.g., hydrogel or nanoparticles) or fabrication technologies (e.g., weaving or braiding). Finally, the authors will provide an opinion as to the future direction of the prevention of tendon adhesion formation in view of scaffold structure and function designs.

Abstract The tendon enthesis is a very complex tissue interface that connects a flexible tissue (tendon) to a stiff tissue (bone). Few available forms of gradient scaffolds with multiple components have been fabricated for applications in vivo because of the complexities of enthesis. In the present work, gradient-poly(e-caprolactone)/calcium phosphate silicate (G-P/C) composite films were fabricated with tape casting technique. Films with different P/C ratio were used to evaluate the material’s ...

Abstract Posttraumatic peritendinous adhesion leads to limb disability. Physical barrier was widely used and thus focus was paid to fabricate the hydrophobic surfaces of electrospun membrane for anti-adhesion. However, current methods are limited and complicated. In this study, beeswax (Wax)/poly-L-lactic acid (PLA) anti-adhesion membranes were fabricated by blending electrospinning of Wax and PLA. The water contact angle was tested to investigate the hydrophobicity of the surfaces. Incorporatio...

Abstract Gradual wear and tear can cause a local inflammatory response in tendons. The trauma and inflammatory reaction eventually impair the biomechanical properties of the tendon. In this study, we prepared lactoferrin-immobilized, heparin-anchored, poly(lactic-co-glycolic acid) nanoparticles (LF/Hep-PLGA NPs) and evaluated their in vitro anti-inflammatory effects on interleukin-1β (IL-1β)-treated tenocytes and in vivo tendon healing effects in a rat model of Achilles tendinitis. Long-term LF-...

Abstract We present here a porous poly (L-lactide)/chitosan (PLLA/CS) composite scaffold with micro/nano-fiber hierarchical structure that was innovatively fabricated by combining 3D printing and thermally induced phase separation technology. Moreover, bioactive quercetin (Qu) was chosen to further functionalize the PLLA/CS scaffold with polydopamine (PDA) layer. The final results showed that the hydrophilicity and mechanical properties of the resulting PLLA/CS-D/Qu scaffold were obviously super...

The problem of tendon and ligament (T/L) regeneration in musculoskeletal diseases has long constituted a major challenge. In situ injection of formable biodegradable hydrogel, however, has been demonstrated to treat T/L injury and reduce patient suffering in a minimally invasive manner. Injectable hydrogel is more suitable than other biological materials due to the special physiological structure of T/L. Most other materials utilized to repair T/L are cell-based, growth factor-based materials, w...

: Tendon is a highly hierarchical and oriented tissue that bears high mechanical strength. Tendon injuries lead to loss of function, disability, and decrease in life quality. Limited healing capacity of tendon tissue leads to scar tissue formation which can affect mechanical strength and cause a retear. Tissue engineering can be the solution for achieving complete and proper healing of tendon. Developed constructs should be mechanically strong while maintaining a proper environment for cell prol...

The human amniotic membrane has been a subject for clinical and basic research for nearly 100 years, but weak rejection has been reported. The purpose of this research is to remove the cellular components of the amnion for eliminating its immune-inducing activity to the utmost extent. The amniotic membrane treated by acid removed the epithelial cell, fibroblast, and sponge layers and retained only the basal and dense layers. In vitro, biological effects of the new material on tenocytes were eval...

Injured tendons are challenging in their regeneration; thus, tissue engineering represents a promising solution. This research tests the hypothesis that the response of amniotic epithelial stem cells (AECs) can be modulated by fiber diameter size of tendon biomimetic fleeces. Particularly, the effect of electrospun poly(lactide-co-glycolide) (PLGA) fleeces with highly aligned microfibers possessing two different diameter sizes (1.27 and 2.5 µm: ha1- and ha2-PLGA, respectively) was tested on the ...
