Özet

Objectives: Ankylosing spondylitis (AS) can cause peripheral arthritis, tendinitis, enthesitis, and axial skeletal involvement. This study aims to determine early tendon damage by shear wave elastography (SWE) for the Achilles tendon in AS patients. Methods: 48 AS patients and 48 asymptomatic individuals were included in the study. Participants were systematically examined with B-mode, power Doppler, and SWE using a high-resolution linear 6–15 MHz probe. Bilateral Achilles tendon stiffness, thickness, and vascularity were evaluated. Measurements were taken from the middle third of the Achilles tendon in the sagittal plane. Difference between the two groups was evaluated with statistical methods. Receiver operating characteristic analysis was performed to test the diagnostic performance of Achilles tendon stiffness. Additionally, the Spearman correlation test examined the relationship between Achilles tendon stiffness and disease duration. Results: The difference between the two groups regarding Achilles tendon stiffness was statistically significant (p < 0.05). It was observed that Achilles tendon stiffness decreased in the patient group compared with the control group. The diagnostic value of Achilles tendon stiffness measured by SWE was found to be high. A negative correlation was detected between disease duration and tendon stiffness (p < 0.05). Conclusion: In patients diagnosed with AS, deterioration in the Achilles tendon structure was observed, and a significant decrease in tendon stiffness compared with the healthy population. It has been determined that these changes in the Achilles tendon are related to the duration of the disease.
