In the macroscopic assessment, while Group C exhibited the thickest AP callus diameter (p=0.02), no significant differences in ML callus diameters existed among the groups (p>0.05). Mechanical testing revealed that Group C had higher torsional strength (p=0.001) and stiffness than Groups A and B (p=0.001) while there was no significant difference between Groups C and D (p>0.05). Biodegradable implant releasing PDGF may have positive effects on fracture healing. Biodegradable implant releasing PDGF may have positive effects on fracture healing. The aim of this study was to compare the effects of local administrations of platelet-rich plasma (PRP) with autologous conditioned serum (ACS) on Achilles tendon healing in a rat model. In this study, 40 male Sprague-Dawley rats, aged 12 months and weighing 350 to 400 g were used. The rats were divided into three groups (n=10 in each group) a control group and two treatment groups (PRP vs ACS). A standardized procedure was applied for the complete rupture and repair of the Achilles tendon in each group. The PRP group received one dose of PRP on the operative area, and ACS group received ACS at 24, 48, and 72 hours after the surgery. The control group received no injection. Animals were sacrificed 30 days after the operation, and tendon healing in each group was assessed histopathologically based on Bonar's semi-quantitative score and Movin's semi-quantitative grading scale. For the biomechanical analyses, unoperated Achilles tendons of all rats in the control and ACS groups were also harvested, and pulliling in rats. In terms of histopathological results, PRP seems to be more effective than ACS for Achilles tendon healing in rats. This study aimed to determine, pre-correction, the potential c
