Shear-Wave Elastography of Regenerated Hamstring Tendons After ACL Reconstruction (SWE-ACL)

Anterior cruciate ligament (ACL) reconstruction using autologous hamstring tendon grafts is a commonly performed procedure. Although the semitendinosus and gracilis tendons demonstrate regeneration at the donor site, the structural and biomechanical properties of the regenerated tissue may differ from native tendon, potentially affecting muscle function. This study aims to quantitatively assess the elasticity of regenerated hamstring tendons using shear-wave elastography (SWE) and to compare these measurements with the contralateral intact side. Additionally, the relationship between tendon elasticity and isokinetic hamstring muscle strength will be evaluated. Secondary objectives include investigating the association between elastography findings and functional clinical outcomes, as well as the effect of postoperative time and patient-related factors such as age and body mass index.
