The purpose of this study is to acquire mechanistic knowledge of the gastrocnemius muscle-Achilles tendon complex behaviour during specific movements in humans through mathematical modelling. Analysis of this muscle-tendon complex was performed to see if already existing muscle-tendon models of other parts of the body could be applied to the leg muscles, especially the gastrocnemius muscle-Achilles tendon complex, and whether they could adequately characterise its behaviour. Five healthy volunteers were asked to take part in experiments where dorsiflexion and plantar flexion of the foot were studied...

BACKGROUND: Transfer of a flexor hallucis longus (FHL) tendon can not only reconstruct the Achilles tendon but also provide ischemic tendinous tissues with a rich blood supply to enhance wound healing. This retrospective study aims to investigate clinical outcomes in patients who underwent repair of Kuwada grade IV chronic Achilles tendon rupture with long hallucis longus tendons harvested using a minimally invasive technique. MATERIALS AND METHODS: 35 patients who were treated for Kuwada grade IV Achilles tendon injuries from July 2006 to June 2011 were included in this retrospective study...

The purpose of this study was to investigate Achilles tendon blood flow in individuals with overpronated feet during non-weight- and weight-bearing positions. Achilles tendon blood flow was measured by means of the pulsatility index (PI) and the resistance index (RI) in 15 male individuals with overpronated feet and 15 counterparts with normal feet, using power Doppler ultrasonography (PDI). Achilles tendon ultrasonographic (US) assessment was performed at its musculo-tendinous junction (MTJ), mid-tendon (MT), and osseotendinous junction (OTJ) at a non-weight-bearing relaxed position (RP) and during two-leg stance (TLS) and one-leg upright stance (OLS)...

Tendinous xanthomas are often thought to be pathognomonic for familial hypercholesterolemia. In this report, we present the case of a young man with a normal lipid profile and Achilles tendon xanthoma. Biochemical and genetic studies confirmed the diagnosis of cerebrotendinous xanthomatosis in this patient. Cerebrotendinous xanthomatosis is a rare autosomal recessive disease associated with xanthoma in tendons and the brain as well as progressive neurologic deficits. Unfortunately, this rare form of reversible dementia is thought to be underdiagnosed...

We have used a murine Achilles tendinopathy model to investigate whether tissue changes (such as collagen disorganization, chondroid metaplasia, and loss of tensile properties) which are broadly characteristic of human tendinopathies, are accompanied by changes in the expression of chromatin-modifying enzymes and the methylation status of promoter regions of tendon cell DNA. Tendinopathy was induced by two intra-tendinous TGF-β1 injections followed by cage activity or treadmill running for up to 28 days. Activation of DNA methyltransferases occurred at 3 days after the TGF-β1 injections and also at 14 days, but only with treadmill activity...

Fluoroquinolones (FQs) are highly effective broad-spectrum antibiotics. Clinical data reveal an increased incidence of tendon pain and rupture in those taking FQs, yet little is known about tendon structural changes. This review synthesises published data on tendon structural changes in people who have taken FQs. Eight databases were searched for potentially relevant articles (Medline, CINAHL, Biological Abstracts, AMED, Web of Knowledge, SCOPUS, SportDiscus and EMBASE) using MeSH and free-text searches. Inclusion and exclusion criteria determined which articles were used for this review...

We report a case of acute generalized pustular bacterid (AGPB) concomitant with erythema nodosum (EN), polyarthritis, and Achilles tendinitis. The patient was admitted with a complaint of fever, widespread plural pustules, erythema, and polyarthralgia. Histopathological examination of the skin lesions demonstrated features of AGBP and EN. Although arthralgia and AGPB can be recognized together, EN and Achilles tendinitis are rare manifestations seen in patients with AGPB. In this case report, we suggest arthralgia, EN, and Achilles tendinitis could coexist with AGPB...

The most common cause of adolescent heel pain is calcaneal apophysitis also known as Sever's disease. The condition may occur in adolescent athletes, particularly those involved in running or jumping activities, during the pubertal growth spurt. The mean age of presentation in Sever's disease is ten, (range 7-15). It presents with posterior heel pain that is worse with activity and relieved by rest in most cases. Sever's disease, Osgood Schlatter's disease (tibial tuberosity) and Sinding-Larsen Johansson syndrome (distal patella) are all overuse syndromes brought about by repetitive submaximal loading and microtrauma...

OBJECTIVES: To assess the elastic properties of the normal Achilles tendon in different age groups by Virtual Touch imaging quantification (VTIQ; Siemens Medical Solutions, Malvern, PA) shear wave elastography. METHODS: A total of 326 healthy volunteers older than 18 years were divided into different groups by sex and age. The thickness, shear wave velocity (SWV) in sagittal and axial sections, and anisotropic coefficient of the Achilles tendon in a state of relaxation were obtained by conventional sonography and Virtual Touch imaging quantification elastography...

Total ankle replacement studies have focused on reporting complications that are directly observed clinically or radiographically, including wound problems, technical errors, implant loosening, subsidence, infection, bone fractures, and heterotopic ossification. However, patients can still experience unresolved pain even when these problems have been ruled out. We initiated a study to more clearly define the relative risk of injury to the anatomic structures in the posterior ankle during total ankle replacement using a third-generation implant system...

The majority of muscles have distinct tendinous attachments to bones; however, only a few tendons develop painful conditions. That simple observation prompts us to ask a few questions. Are there commonalities in morphology and pathology among the painful tendons? What contributes to the propensity for pathology in some, but not all, tendons? And, consequently, should all tendinopathies be managed equally? Two common tendinopathies are those affecting the Achilles and supraspinatus, which are presented in this special issue and serve as excellent models to discuss similarities and contrasts...

The myotendinous junction (MTJ) is the weakest element in the muscle-tendon unit of the heel, and thus the most susceptible to injuries. The scarcity of adequate treatments means that tendinitis is a major concern to athletes and other groups who depend on their physical fitness, although green tea and glycine have both been shown to have beneficial effects on the inflammation. The present study investigated the remodeling effects of green tea and glycine in the MTJ of rats with tendinitis. For this, male Wistar rats were divided into five groups: animals without tendinitis and animals with tendinitis; animals with tendinitis supplied with green tea; animals with tendinitis supplied with a glycine diet; animals with tendinitis supplied with a green tea and glycine diet...

Patients with inflammatory bowel disease often have extraintestinal manifestations (EIMs) involving almost all organ systems, but little has been reported on Achilles tendinitis. Herein, we present a unique case of Achilles tendinitis, which manifested shortly after initiation of mesalazine therapy for ulcerative colitis. A 26-year-old Japanese woman with bloody diarrhea and abdominal cramps lasting for 7 days was referred to our hospital. The Lichtiger clinical activity index (CAI) score was 9 at the first visit...

Tendinous and subcutaneous xanthomas are nodular deposits of lipid-filled macrophages, which commonly form on the Achilles tendon, hands, feet, elbows, and knees. These nodules are frequently associated with familial hyperlipidemia, a group of diseases involving impaired cholesterol metabolism, and the accelerated development of atherosclerotic plaques. Since xanthomas may precede the diagnosis of hyperlipidemia, early identification can lead to preventative treatment that reduces the risk and morbidity of cardiovascular disease, including myocardial infarction...

Ultrasound (US)-guided corticosteroid injection has been shown to be safe and effective for varied causes of plantar fasciitis; however, its use for Achilles tendinitis is controversial. We studied the efficacy and changes in US findings at Achilles enthesitis after corticosteroid injection in patients with spondyloarthropathy (SpA). Patients with SpA with symptomatic Achilles enthesitis, refractory to 6 weeks of full-dose NSAIDs, were offered US-guided local corticosteroid injection. Injected entheses were examined by US (both B mode and power Doppler) at baseline and 6 weeks after injection...

Patients undergoing InterStim implantation often have comorbidities, which require magnetic resonance imaging (MRI) for diagnosis. Although MRI of the head has been recently approved for use with the InterStim neurostimulator, imaging of other regions remains controversial. We present a case of Achilles tendinitis diagnosed on MRI of the ankle in a patient with an InterStim device. The neurostimulator was deactivated, and using a transmit/receive extremity coil, the left ankle was imaged without any adverse events...

Haglund's syndrome produces posterior impingement of the heel, which is caused by a posterosuperior calcaneal exostosis, known as Haglund's deformity, associated with Achilles tendinitis and retrocalcaneal bursitis. Its pathogenesis is unknown. We report two cases that were diagnosed clinically and confirmed radiographically. One patient was treated conservatively and the other underwent surgery. The diagnosis is based on clinical signs and radiological images, using the measurement of the parallel pitch lines, in a lateral radiograph of the ankle...
