Chronic Achilles tendinosis is a condition with unknown aetiology and pathogenesis, most often, but not always, associated with painful nodular thickening of the tendon. In this investigation, 28 tendons (21 patients) with a painful nodule located at the 2–6 cm level in the tendon, and 20 normal (pain-free) tendons, were examined with grey-scale ultrasonography combined with colour Doppler examination. In all tendons with a painful nodule, but not in any of the normal pain-free tendons… Expand
Is vasculo-neural ingrowth the cause of pain in chronic Achilles tendinosis?
TLDR
Findings which support neovessels and accompanying nerves being the possible source of pain in chronic mid-portion Achilles tendinosis are demonstrated. Expand
Neovascularisation in chronic tendon injuries detected with colour Doppler ultrasound in horse and man: implications for research and treatment
TLDR
The neovessels found in the horse tendons looked similar to what has recently been presented in human Achilles tendons, motivating evaluation of the same treatment, a sclerosing injection demonstrated recently to give promising results in the treatment of chronic Achilles tendon injuries (tendinosis) in humans. Expand
Sclerosing therapy in chronic Achilles tendon insertional pain-results of a pilot study
TLDR
Treatment only focusing on sclerosing the area with neovessels showed promising short-term clinical results in this small pilot study, and the findings support further studies, preferably in a randomised manner. Expand
How to diagnose plantaris tendon involvement in midportion Achilles tendinopathy - clinical and imaging findings
TLDR
US + CD directly, and clinical assessment indirectly, can detect a close by located plantaris tendon in a high proportion of patients with midportion Achilles tendinopathy. Expand
Achilles tendon pain intensity and level of neovascularization in athletes as determined by color Doppler ultrasound
TLDR
There was a low prevalence of Achilles tendinopathy, tenderness, and neovascularization in this population of varsity athletes, and Neov vascularization was seen in both a painful and a non‐painful tendon. Expand
High intratendinous lactate levels in painful chronic Achilles tendinosis. An investigation using microdialysis technique
TLDR
In this investigation the microdialysis technique was used to study the concentrations of lactate in Achilles tendons with painful chronic tendinosis and in normal pain‐free tendons, where the painful thickening corresponded to a widened tendon and structural tendinotic changes. Expand
Pitfalls in the study of neovascularisation in achilles and patellar tendinopathy: a review of important factors for clinicians to consider and the need for greater standardisation
TLDR
There is a need for international agreement on a standardised protocol in the assessment of the microvascularity of tendons, which could then help determine if the quantification of “neovascularisation” is a reliable and clinically relevant finding. Expand
Nerve-related characteristics of ventral paratendinous tissue in chronic Achilles tendinosis
TLDR
The nerve-related characteristics of the area targeted by the polidicanol injection treatment for Achilles tendinosis, shown here for the first time, suggest that the area investigated is under marked influence by the nervous system, including sympathetic and sensory components. Expand
Neovascularisation in chronic painful patellar tendinosis—promising results after sclerosing neovessels outside the tendon challenge the need for surgery
TLDR
Treatment with sclerosing injections, targeting the area with neovessels in patellar tendinosis, has the potential to cure the pain in the tendons and also allow the patients to go back to full patellAR-tendon loading activity. Expand
Partial mid-portion Achilles tendon ruptures: new sonographic findings helpful for diagnosis
TLDR
US and Doppler examination can be helpful tools to diagnose partial mid-portion Achilles tendon ruptures, and the characteristic findings of a disrupted dorsal tendon line and high blood flow in the structurally abnormal dorsal tendon indicate a partial rupture. Expand

Degenerative Achilles tendon disease: assessment by magnetic resonance and ultrasonography.
TLDR
MR was superior in the detection of incomplete tendon rupture and in the evaluation of various stages of chronic degenerative changes and only if US remains unclear, an additional MR study should be performed and together with the clinical diagnosis indication for surgery can be made more efficient.

Tendon pathology in long-standing achillodynia. Biopsy findings in 40 patients.
TLDR
Changes in the fiber structure and arrangement, as well as increased amounts of interfibrillar GAG, appear to be characteristic morphological features in Achilles tendons with long-standing achillodynia and ultrasonographic widening, which may indicate that achillingnia is due to local disturbances in connective tissue metabolism or circulation or to both.

Imaging in chronic achilles tendinopathy: a comparison of ultrasonography, magnetic resonance imaging and surgical findings in 27 histologically verified cases
TLDR
Comparisons of ultrasonography and MRI in chronic achilles tendinopathy with regard to the nature and severity of the lesion suggest these methods give similar information and may have their greatest potential as prognostic instruments. Expand
Blood Flow in Chronic Achilles Tendinopathy
TLDR
Thirty five patients, most of them athletes, with chronic Achilles tendinopathy were enrolled in a study of tendon blood flow using laser Doppler flowmetry at rest and during physical provocation by passive stretch and contraction of the triceps, demonstrating a similar vascular response to physical loading.

Ultrasound diagnosis of Achilles tendon pathology in runners.
TLDR
A clinical and ultrasonic study was performed on 47 middle and long distance runners referred to the Authors with problems of the Achilles tendon. Expand
Chronic Achilles Tendinosis
TLDR
Treatment with heavy load eccentric calf muscle training showed very promising results and may possibly reduce the need for surgical treatment of tendinosis located in the midportion of the Achilles tendon. Expand
Histopathology of Common Tendinopathies
TLDR
The histopathological findings in athletes with overuse tendinopathies are consistent with those in tendinosis — a degenerative condition of unknown aetiology, which may have implications for the prognosis and timing of a return to sport after experiencing tendon symptoms. Expand
Chronic Achilles Tendinopathy: A Survey of Surgical and Histopathologic Findings Mats
TLDR
Tendinosis appears to be the major lesion in chronic Achilles tendinopathy; the paratenon is rarely involved and important features are a lack of inflammatory cells and a poor healing response. Expand
Ultrasonography in the Differential Diagnosis of Achilles Tendon Injuries and Related Disorders
TLDR
US can reliably be used for locating the Achilles tendon abnormality, estimating its severity, and determining most of the conditions requiring surgical intervention, but it is not completely reliable for diagnosing peritendinitis and tendinitis, and it cannot be used to differentiate partial tendon ruptures from focal degenerative lesions. Expand
Etiology, Histopathology, and Outcome of Surgery in Achillodynia
TLDR
Surgical treatment was beneficial in most cases, despite a relatively high complication rate, and achillodynia is not always associated with excessive physical activity. Expand
