Tendon tendinopathy achilles

James Watson, Robert M Barker-Davies, Alexander N Bennett, Daniel T P Fong, Patrick C Wheeler, Mark Lewis, Craig Ranson
Objective: Several lower limb tendinopathy treatment modalities involve identification of pathological paratendinous or intratendinous neovascularisation to target proposed co-location of painful neoneuralisation. The ability to reliably locate and assess the degree of neovascularity is therefore clinically important. The Modified Ohberg Score (MOS) is frequently used to determine degree of neovascularity, but reliability has yet to be established among Sport and Exercise Medicine (SEM) consultants...

BACKGROUND: Haglund syndrome is a common cause of heel pain. Risk for tendon detachment after calcaneoplasty can exist. Open Achilles tendon detachment, calcaneoplasty, bursectomy, pathologic tendon-tissue debridement, and tendon reattachment of the Achilles tendon is a common surgical management of Haglund syndrome combined with insertional Achilles tendinopathy. The aim of this study was to describe the endoscopic calcaneoplasty and anchor suture augmentation of the Achilles insertional area, and the results obtained in patients with an increased risk of Achilles tendon rupture after calcaneoplasty...

OBJECTIVE: The aim of this study to evaluate the effects of autologous conditioned serum (ACS) on the healing of transected rat Achilles tendons via the assessment of biomechanical and histological parameters. METHODS: The study was conducted on 45 male Sprague-Dawley rats. Five rats were used as donors for ACS preparation. Animals were randomly assigned to the experimental or control group. In both groups, the Achilles tendon was cut transversally and then sutured...

Our goal was to develop a novel technique for inducing Achilles tendinopathy in animal models which more accurately represents the progressive histological and biomechanical characteristic of chronic Achilles tendinopathy in humans. In this animal research study, forty-five rabbits were randomly assigned to three groups and given bilateral Achilles injections. Low dose (LD group) (n = 18) underwent a novel technique with three low-dose (0.1mg) injections of collagenase that were separated by two weeks, the high dose group (HD) (n = 18) underwent traditional single high-dose (0...

BACKGROUND: Non-invasive treatment is not always successful in patients with Achilles tendon disorders, and surgical treatment is instituted as the next step. There is sparse knowledge about the diagnoses, pain levels before surgery, surgically confirmed pathologies and postoperative complications in large patient groups. AIMS: To study the diagnoses, pain scores before surgery, macroscopic surgical findings and postoperative complications in a series of patients treated for Achilles disorders...

Reasons for the development of chronic tendon pathologies are still under debate and more basic knowledge is needed about the different diseases. The aim of the present study was therefore to characterize different acute and chronic Achilles tendon disorders. Achilles tendon samples from patients with chronic tendinopathy (n = 7), chronic ruptures (n = 6), acute ruptures (n = 13), and intact tendons (n = 4) were analyzed. The histological score investigating pathological changes was significantly increased in tendinopathy and chronic ruptures compared to acute ruptures...

BACKGROUND: Several risk factors have been suggested in the development of Achilles tendinopathy, but large-scale prospective studies are limited. PURPOSE: To investigate the role of the vascular response to activity of the Achilles tendon, tendon thickness, ultrasound tissue characterization (UTC) of tendon structure, and foot posture as possible risk factors in the development of Achilles tendinopathy. STUDY DESIGN: Cohort study; Level of evidence, 2...

The differential diagnosis of heel pain is extensive, but a mechanical etiology is the most common. The specific anatomic location of the pain can help guide diagnosis. The most common diagnosis is plantar fasciitis, which leads to medial plantar heel pain, especially with the first weight-bearing steps after rest. Other causes of plantar heel pain include calcaneal stress fractures (progressively worsening pain after an increase in activity or change to a harder walking surface), nerve entrapment or neuroma (pain accompanied by burning, tingling, or numbness), heel pad syndrome (deep, bruise-like pain in the middle of the heel), and plantar warts...

When insertional Achilles tendinopathy is addressed surgically via a central-Achilles splitting approach, the calcaneal osteotomy has classically been performed from distal to proximal. We describe a simple proximal to distal technique that allows optimal resection of both the calcaneal exostosis and Achilles enthesophyte, minimizes risk to the soft tissues and skin, provides a bony attachment surface parallel to the axis of the Achilles tendon, and avoids the risk of osteotomy extension into the subtalar joint...

Tendon injury belongs to the less known side effects of some drugs, reported until recently only for glucocorticoids and fluoroquinolones. To date, some other classes of drugs such as statins, aromatase inhibitors, anabolic steroids, potentially causing tendon injury, have been added to the list. The authors discuss the most common clinical presentations, diagnosis, and management as well as latest experimental data regarding this issue. The most often, the Achilles tendon is affected, however, nearly every tendon of the entire body may be affected...

OBJECTIVE: The aim of the study was to examine the quantitative tissue properties of the Achilles tendon and plantar fascia using a handheld, non-invasive MyotonPRO device, in order to generate normal values and examine the biomechanical relationship of both structures. DESIGN: Prospective study of a large, healthy sample population. PARTICIPANTS: The study sample included 207 healthy subjects (87 males and 120 females) for the Achilles tendon and 176 healthy subjects (73 males and 103 females) for the plantar fascia...

Metabolic factors such as cholesterol appear to play an important role in the development of Achilles tendinopathy. There is, however, no morphologic proof explaining the link between high cholesterol and tendinopathy. As apolipoprotein A1 (Apo-A1) is essential for reverse cholesterol transport, it may be related to cholesterol overload in tendon. Nothing is known about Apo-A1 expression in tendon tissue. We examined the distribution of Apo-A1 protein in biopsies from normal and tendinopathy affected human Achilles tendons, and APOA1 mRNA production from cultured human hamstring tenocytes...

Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, sex, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibers, and subsequent increase in noncollagenous matrix...

Due to the increasing age of our society and a rise in engagement of young people in extreme and/or competitive sports, both tendinopathies and tendon ruptures present a clinical and financial challenge. Tendon has limited natural healing capacity and often responds poorly to treatments, hence it requires prolonged rehabilitation in most cases. Till today, none of the therapeutic options has provided successful long-term solutions, meaning that repaired tendons do not recover their complete strength and functionality...

Issue: Lower extremity tendon injuries often occur in physically active individuals. Most ruptures not involving great force are diagnosed in patients presenting underlying tendon degenerations. This also applies to patients taking medications because of a disease. We have observed several cases of bilateral Achilles tendon ruptures in patients who have been taking cortisone for a long period. We treated a healthy colleague (neurologist) in our clinic who sustained ruptures of the Achilles tendon on the left side (2012) and the peroneus brevis tendon on left side (2015) and right side (2016) after minimal traumata...

BACKGROUND: Midportion Achilles tendinopathy (AT) can cause long-term absence from sports participation, and shows high recurrence rates. It is important that the decision to return to sport (RTS) is made carefully, based on sharply delimited criteria. Lack of a well-defined definition and criteria hampers the decision to RTS among athletes with AT, and impedes comparison of RTS rates between different studies. OBJECTIVE: The aim of this study was to systematically review the literature for definitions of, and criteria for, RTS in AT research...

NEW FINDINGS: What is the central question of this study? The aim was to determine the effect of mid-portion Achilles tendinopathy (MAT) on free Achilles tendon three-dimensional morphology and volume at rest and under load in people with unilateral MAT. What is the main finding and its importance? Tendinopathic tendon had a larger resting tendon cross-sectional area and anteroposterior diameter relative to healthy tendon. When loaded, tendinopathic tendon experienced a reduction in transverse morphology (i...

Achilles tendinopathy can be a chronic disabling condition affecting both athletic and sedentary patients. Multiple new treatment approaches have developed, including shock wave therapy and various types of injection. One of the novel treatment methods used is the injection of Aethoxysklerol or polidocanol, a sclerosing substance injected under ultrasound guidance targeting areas of neovascularisation. We report the case of a 78-year-old lady who suffered a complete Achilles tendon rupture following injection of Aethoxysklerol...

We thank Wu (2017) and the editors for the opportunity to provide greater discussion on the association of tendon shear wave velocity (SWV) with potentially important covariates including sex and age. We would like to first clarify that we did not directly compare the Achilles and patellar tendinopathy groups. Instead, the (most) affected tendon from each tendinopathy group was compared with a matched tendon from the healthy control group. This article is protected by copyright. All rights reserved.
