Background: Despite recent advancements in surgical techniques, the repair of tendon rupture remains a challenge for surgeons. The purpose of this study was to develop novel doxycycline-loaded biodegradable nanofibrous membranes and evaluate their efficacy for the repair of Achilles tendon rupture in a rat model. Materials and Methods: The drug-loaded nanofibers were prepared using the electrospin-ning process and drug release from the prepared membranes was investigated both in vitro and in vivo. Furthermore, the safety and efficacy of the drug-loaded nanofibrous membranes were evaluated in rats that underwent tendon surgeries. An animal behavior cage was employed to monitor the post-surgery activity of the animals. Results: The experimental results demonstrated that poly(D,L-lactide-co-glycolide) (PLGA) nanofibers released effective concentrations of doxycycline for more than 40 days post-surgery, and the systemic plasma drug concentration was low. Rats receiving implantation of doxycycline-loaded nanofibers also showed greater activities and stronger tendons post-operation. Conclusion: Nanofibers loaded with doxycycline may have great potential in the repair of Achilles tendon rupture.
