L17 5io broadband compact linear array transducer

The Achilles tendons of all animals were imaged with high-frequency ultrasound before surgery and at the end point of the experiments before explanting the tendons. Ultrasound imaging was performed with an ultrasound unit (iU22 Ultrasound System, Philips Healthcare, Switzerland) with a linear high-frequency hockey-stick probe of 17.5 MHz (L17-5io Broadband Compact Linear Array Transducer, Philips Healthcare, Switzerland). The examination protocol consisted of a dynamic imaging of the gliding Achilles tendon by moving the flexor digitorum superficialis of the rabbit paw. All measurements were done freehand. The films of the gliding tendons were scored with 0 = good gliding (no adhesion), 1 = middle gliding (some adhesion) and 2 = no gliding (maximum adhesion) (see Supplementary Videos 1 and 2 (see Supplementary Material available online at http://dx.doi.org/10.1155/2014/656240)). Colour gain adjustment was calibrated on the counter leg that was not treated (healthy side).
