Abstract
The present study investigates the effect of transosseous low-intensity pulsed ultrasound (LiUS) during lingamentization process on the healing at tendon graft-bone interface in rabbits. Analysis of the RT-PCR products showed statistically significant up-regulation of genes encoding collagen type I and tRNAGly in the study group compared to the control group. Histological examination indicated a faster healing rate and a more efficient lingamentization process after ultrasound treatment. Our results suggest that transosseous application of LiUS enhances the healing rate of the tendon graft-bone interface, possibly by affecting the expression levels of significant genes.
