Résumé

Quadriceps strength and patellar tendon (PT) mechanical properties are directly linked and intimately related to daily activities and lower limb function. However, the correlation between knee extension torque (KT) and PT Young's modulus (E) directly measured is still unknown. We evaluated directly by means of supersonic shearwave imaging (SSI) the elastic properties of PT in healthy young men and analyzed its correlation with KT. Twenty-two healthy young males were included and both knees were examined. The EM of the PT in the dominant and non-dominant legs was assessed by SSI elastography. KT in maximal voluntary contraction was measured with an isokinetic dynamometer. No correlations between KT and PT EM were observed in dominant or non-dominant side (p= 0.458 and 0.126, respectively). No significant differences in KT or PT E were observed between both legs (p= 0.096 and 0.722 respectively). No significant correlations were found between KT and PT E, suggesting that quadriceps strength is not an accurate predictor for PT mechanical properties. PT habitual loading pattern can play a determinant role in determining its mechanical properties, regardless of quadriceps strength.
