Abstract: Objective To investigate the reliability of ultrasound tissue characterization (UTC) for quantifing the integrity of achilles tendon and patellar tendon in subjects without tendinopathy.Methods From August, 2016 to April, 2017, testers A and B quantified integrity of achilles tendon and patellar tendon of dominant legs from 43 subjects without tendinopathy by UTC in random order respectively. Tester B quantified integrity of patellar tendon of dominant legs from other 22 subjects without tendinopathy by the same way, and repeated the measurements the next day. Interclass correlation coefficient (ICC) and the minimum detectable different (MDD) were calculated.Results The ICC of inter-rater reliability of achilles tendon assessment was 0.492 to 0.735, MDD was 0.3% to 3.0%. The ICC of inter-rater reliability of patellar tendon assessment was 0.383 to 0.678, MDD was 0.3% to 4.4%. The ICC of intra-rater reliability of patellar tendon assessment was 0.525~0.760, MDD was 0.6% to 5.3%.Conclusion The test-retest reliability of UTC for the quantification of integrity structure of achilles tendon and patellar tendon is satisfactory with little error, the inter-rater reliability need to be improved.which is a accurate and feasible tool to quantify tendon by the same tester.
