Purpose
The Achilles tendon is the most commonly ruptured tendon in the body [1].
Rupture of the Achilles tendon often requires surgical repair and extended immobilization,
which may lead to prolonged rehabilitation [2].
In addition,
the ruptured Achilles tendon heals slowly due to the limited blood supply and slow cell turnover [3].
Biomechanical properties and viscoelasticity of the repaired Achilles tendon are different from non damaged,
and it is of great value for sport-related persons and ballet dancers. If repaired tendons are too stiff and hence not being able to absorb sufficient energy during the motion,
they are more likely to be injured again Fig. 1 [4].
Postsurgical late complications include infection,
development of adhesions,
decreased ankle range of motion,
muscle atrophy and weakness,
nerve injury,
blood clots (deep venous thrombosis,
pulmonary embolism),
skin sloughs,
heel ulcers,
hematoma formation,
and re-rupture of the tendon.
Therefore,
it is important to evaluate the tendon stiffness following repair of Achilles tendon.
Sonoelastography (SE) is a non-invasive ultrasonographic imaging technique [5].
The best report assessing the mechanical properties of a repaired Achilles tendon after surgery was performed by Zhang et al [6].
Recently,
it was reported that reabilitation period of sport-related persons is different from non-sport-related,
this is due to different motional activities during reabilitation [7].
The purpose of the study was to compare sonoelastography features and Strain Ratio (SR) of the Achilles tendon after open surgery in different sport activity persons.
