The present study aimed to determine whether distinct sets of tendon properties are seen in athletes engaged in sports with contrasting requirements for tendon function and structural integrity. Patellar and Achilles tendon morphology and force-deformation relation were measured by combining ultrasonography, electromyography and dynamometry in elite ski jumpers, distance runners, water polo pla...

OBJECTIVES The plantaris tendon has recently been described as a possible important factor in midportion Achilles tendinopathy. Ultrasound tissue characterisation (UTC) is a method to study tendon structure (matrix integrity). The effect of plantaris tendon removal on Achilles tendon structure was studied using UTC. DESIGN AND SETTING Prospective case series study at one centre. PARTICIPANT...

Introduction Achilles tendon ruptures are a common problem preventing athletic participation and daily life activities, often requiring surgical repair and extensive rehabilitation. In rabbit Achilles tenocytes in vitro, down-regulation of the proteoglycan decorin suppressed the expression of TGF-b1, a growth factor associated with fibrotic scar. Similarly, in the medial collateral ligament in ...

Tracking Achilles tendon cross sectional area (CSA) changes may help clinicians understand exercise adaptations and Achilles tendon injury mechanisms. To track adaptations in the Achilles tendon in response to a cross country season. Design Longitudinal study. Musculoskeletal (MSK) ultrasound images were obtained in a research laboratory. Cross country athletes ran with no restrictions outdoo...

Anatomic and operative textbooks and current literature do not clearly describe the Achilles tendon interface to the calcaneal tuberosity. We dissected 51 specimens to identify the detailed anatomy of the Achilles tendon insertion. Achilles tendon fascicles expanded from the anterior aspect of the distal Achilles tendon over the retrocalcaneal bursa to the anterior part of the Haglund's tuberos...

The rate of re-rupture of Achilles tendon after surgical treatment were reported to 1.7-5.6% previously. Re-rupture of Achilles tendon generally occurs subcutaneously. We experienced two rare cases of the open re-ruptures of Achilles tendon with a transverse wound perpendicular to the primary surgical incision. Re-rupture occurred 4 and 13 weeks after surgical treatment. We suggest that open re...

AIMS The objective of the study was to investigate the value of acoustic radiation force impulse (ARFI) and its application in Achilles tendon elasticity of healthy volunteers. METHODS Bilateral Achilles tendons of 56 healthy individuals were included in the study. The subjects were divided into four age groups. Shear wave velocities (SWVs) of each tendon in the states of relaxation and tensi...

BACKGROUND This study evaluated the clinical application of high-frequency color Doppler ultrasonography (HFCDU) in the diagnosis, treatment, and rehabilitation of Achilles tendon injury. MATERIAL AND METHODS A total of 68 patients with suspected Achilles tendon injury were examined by HFCDU. There were 42 Achilles tendon injury patients who underwent surgery, and they were randomly divided int...
