Bioengineered Strategies for Tendon Regeneration

Their important mechanical function predisposes tendons to injury and rupture, becoming a worldwide
clinical problem. Commonly injured tendons include the rotator cuff, finger flexors, patellar, and
Achilles tendon [1]. As poor cellular and vascular tissues [2], tendons present some healing constraints,
typically requiring surgical intervention. Available reparative surgeries rely on tissue replacement with
auto- or allografts [3], which are often accompanied with donor site morbidity, pain, inferior functionalities,
and eventually graft failure.
Due to the market demand, commercial substitutes for tendon repair have been developed as biological
and synthetic scaffolds.
