“…In a large prospective study of 652 healthy tendons, Fu et al found a gradual increase in the thickness of the Achilles tendon with age, but no significant correlation between age and tendon stiffness with SWE [47] . These findings were consistent with those of other studies that found no correlation between SWE and age-related changes in tendon stiffness [17] , [25] , [48] . Slane et al demonstrated age-related spatial variation in elasticity of the Achilles tendon as measured by SWV, which may explain the lack of consensus for UE findings in the ageing Achilles tendon [27] .…”

“…As such, subtle changes in the probe and tendon placement alter the values obtained for SWV and Young's modulus and therefore the measured tendon stiffness. For example, values for SWV and Young's modulus have been shown to significantly increase (i.e., stiffer tendon) as the ankle progresses from a more relaxed, plantarflexed position to a dorsiflexed position [19] , [25] , [26] , [27] .…”

“…Normative SWE values for healthy Achilles, patellar, and RTC tendons have been studied ( Table 1 , Table 2 , Table 3 ). The measured elasticity modulus and SWV for the Achilles tendon have ranged from 74.4 to 779.5 kPa and 5.1–12.0 m/s, respectively [17] , [19] , [22] , [25] , [26] , [27] . SWV for the RTC has been shown to range from 2.9 to 9.0 m/s, with one study measuring the elasticity modulus at 31.2 kPa [17] , [36] , [37] , [38] .…”

At the patellar tendon, SWE has been shown to have excellent intraobserver (CC: 0.831–0.966) and interobserver (CC: 0.71–0.821) agreement [49] , [69] .…”

Ultrasound elastography (UE) and ultrasound tissue characterisation (UTC) are two newer modes of ultrasound (US) which have begun to attract scientific interests as ways to improve tendon characterisation. These modes of US show early promise in improved diagnostic accuracy, prediction of at-risk tendons and prognostication capability beyond conventional grey-scale US. Here, we provide a review of the literature on UE and UTC for Achilles, patellar and rotator cuff tendons.The translational potential of this article: The present literature indicates that UE and UTC could potentially increase the clinician's ability to accurately diagnose the extent of tendon pathology, including preclinical injury.

“…By considering the medium as elastic and homogeneous, the shear modulus (μ) given in kPa is deduced using the equation: μ = ρV 2 , where ρ is the density (assuming ρ = 1000 kg m −3 ) (Bercoff et al 2004). This technique has been used to assess tendon mechanical properties in healthy volunteers (Aubry et al 2011, Hug et al 2013, DeWall et al 2014 and in people with Achilles (Aubry et al 2015) and patellar tendinopathy (Zhang et al 2014). However, the SSI technique has two main limitations when applied to the tendon.…”

In vivoquantification of the shear modulus of the human Achilles tendon during passive loading using shear wave dispersion analysis

The shear wave velocity dispersion was analyzed in the Achilles tendon (AT) during passive dorsiflexion using a phase velocity method in order to obtain the tendon shear modulus (C 55). Based on this analysis, the aims of the present study were (i) to assess the reproducibility of the shear modulus for different ankle angles, (ii) to assess the effect of the probe locations, and (iii) to compare results with elasticity values obtained with the supersonic shear imaging (SSI) technique. The AT shear modulus (C 55) consistently increased with the ankle dorsiflexion (N = 10, p < 0.05). Furthermore, the technique showed a very good reproducibility (all standard error of the mean values <10.7 kPa and all coefficient of variation (CV) values ⩽ 0.05%). In addition, independently from the ankle dorsiflexion, the shear modulus was significantly higher in the proximal location compared to the more distal one. The shear modulus provided by SSI was always lower than C55 and the difference increased with the ankle dorsiflexion. However, shear modulus values provided by both methods were highly correlated (R = 0.84), indicating that the conventional shear wave elastography technique (SSI technique) can be used to compare tendon mechanical properties across populations. Future studies should determine the clinical relevance of the shear wave dispersion analysis, for instance in the case of tendinopathy or tendon tear.
