Achilles tendinopathy is a common overuse condition affecting the adult population. The incidence is on the rise because of greater participation of people in recreational or competitive sporting activities. There are several treatment options available both non-operative and operative. Ultrasound-guided dry needling and high-volume image-guided injection is relatively a new procedure. The aim of this study was to find out the effectiveness of dry needling and HVIGI in the management of mid-portion chronic Achilles tendinopathy by performing a literature review...

BACKGROUND: Various treatment modalities have been described for Achilles tendinopathy with varying degrees of success. The rationale for the gastrocnemius recession procedure is to decrease the mechanical overload of the Achilles tendon arising from an equinus contracture. METHODS: We retrospectively reviewed 25 patients who underwent an isolated gastrocnemius recession procedure at our institution between May 2013 and April 2015 by a single surgeon. Clinical outcome was evaluated on the basis of pain, utilizing visual analog scale (VAS) scores and the Foot Function Index (FFI) by telephonic interview...

When compared to placebo, acetaminophen (APAP) reduces tendon stiffness and collagen cross-linking. APAP also enhances the exercise-induced increase in peritendinous levels of IL-6. Elevated levels of IL-6 are associated with tendinopathy, thus we hypothesized that chronic, elevated peritendinous IL-6 would alter tendon extracellular matrix (ECM). IL-6 (∼3000pgml(-1)) was injected (3dwk(-1) for 8-wks) into the Achilles peritendinous region of male Wistar rats (n=16) with the opposite leg serving as a sham...

Mid-portion Achilles tendinopathy is a common injury in sporting populations. There is conflicting evidence about the best approach to conservative management. This report focuses on the rehabilitation of an Achilles tendinopathy utilising osteopathic manual therapy (OMT) and a structured exercise program in a semi-professional volleyballer. The patient presented with a 4-month history of right mid-portion Achilles tendon pain that begun after a lateral inversion sprain of the right ankle. The primary complaint was pain impacting the patients vertical jump performance...

Chronic and acute tendinopathies are difficult to treat and tendon healing is generally a very slow and incomplete process and our general understanding of tendon biology and regeneration lags behind that of muscle or bone. Although still largely unexplored, several studies suggest a positive effect of nutritional interventions on tendon health and repair. With this study, we aim to reveal effects of a high-glucose diet on tendon neoformation in a non-diabetic rat model of Achilles tenotomy. After surgery animals received either a high-glucose diet or a control diet for 2 and 4 weeks, respectively...

BACKGROUND: Fluoroquinolone use has been known to be associated with tendinopathy and tendon rupture for over 30 years. Hand and wrist involvement has been reported rarely, yet without early recognition and withdrawal of the fluoroquinolone, there is potential for significant morbidity. METHODS: We searched Medline using a comprehensive search strategy for fluoroquinolones and tendinopathy of the hand and wrist, and provide a case report of a possible levofloxacin-related tendon rupture in a patient with a previous mutilating hand injury...

BACKGROUND: Achilles tendinopathy (AT) is associated with persistent pain leading to a significant physical and psychological burden. Psychosocial factors are considered to be important mediators following exercise interventions. Despite the recognition of the importance of psychosocial variables in persistent MSK disorders, there is a distinct lack of qualitative research investigating psychosocial factors in AT. PURPOSE: To qualitatively explore the perceptions and experiences of people with AT prior to an intervention study...

Achilles tendinopathy or rupture and anterior cruciate ligament (ACL) rupture are substantial injuries affecting athletes, associated with delayed recovery or inability to return to competition. To identify genetic markers that might be used to predict risk for these injuries, we performed genome-wide association screens for these injuries using data from the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort consisting of 102,979 individuals. We did not find any single nucleotide polymorphisms (SNPs) associated with either of these injuries with a p-value that was genome-wide significant (p<5x10-8)...

BACKGROUND: The structural pathology of Achilles tendon (AT) ruptures resembles tendinopathy, but the causes remain unknown. Recently, a number of diseases were found to be attributed to bacterial infections, resulting in low-grade inflammation and progressive matrix disturbance. The authors speculate that spontaneous AT ruptures may also be influenced by the presence of bacteria. HYPOTHESIS: Bacteria are present in ruptured ATs but not in healthy tendons. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

BACKGROUND: Chronic tendinopathy is a commonly occurring clinical problem that affects both athletes and inactive middle-aged patients. Although some studies have shown that different platelet-rich plasma (PRP) preparations could exert various therapeutic effects in vitro, the role of leukocytes in PRP has not yet been defined under tendinopathy conditions in vivo. PURPOSE: This study compared the effects of the intratendon delivery of leukocyte-poor PRP (Lp-PRP) versus leukocyte-rich PRP (Lr-PRP) in a rabbit chronic tendinopathy model in vivo...

Sonographically detectable intratendinous blood flow (IBF) is found in 50%-88% of Achilles tendinopathy patients as well as in up to 35% of asymptomatic Achilles tendons (AT). Although IBF is frequently associated with tendon pathology, it may also represent a physiological regulation, for example, due to increased blood flow in response to exercise. Therefore, this study aimed to investigate the acute effects of a standardized running exercise protocol on IBF assessed with Doppler ultrasound (DU) "Advanced dynamic flow" in healthy ATs...

BACKGROUND: Although survival of transplanted stem cells in vivo and differentiation of stem cells into tenocytes in vitro have been reported, there have been no in vivo studies demonstrating that mesenchymal stem cells (MSCs) could secrete their own proteins as differentiated tenogenic cells. Purpose/Hypothesis: Using a xenogeneic MSC transplantation model, we aimed to investigate whether MSCs could differentiate into the tenogenic lineage and secrete their own proteins. The hypothesis was that human MSCs would differentiate into the human tenogenic lineage and the cells would be able to secrete human-specific proteins in a rat tendon injury model...

In this study, we propose a method for quantitative prediction of changes in concentrations of a number of key signaling, structural and effector molecules within the extracellular matrix of tendon. To achieve this, we introduce the notion of elementary cell responses (ECRs). An ECR defines a normal reference secretion profile of a molecule by a tenocyte in response to the tenocyte's local strain. ECRs are then coupled with a model for mechanical damage of tendon collagen fibers at different straining conditions of tendon and then scaled up to the tendon tissue level for comparison with experimental observations...

OBJECTIVE: To investigate the factors affecting prognosis of extracorporeal shockwave therapy (ESWT) for chronic refractory Achilles tendinopathy (AT). METHODS: Thirty-six patients (48 consecutive feet) with chronic AT (>6 months) and who underwent ESWT for 'poor' or 'fair' grade in Roles-Maudsley Score (RMS) after unsuccessful conservative treatment were included in the present study. A maximum of 12 sessions of ESWT were conducted until treatment success: RMS reached 'good' or 'excellent'...

Haglund's syndrome is impingement of the retrocalcaneal bursa and Achilles tendon caused by a prominence of the posterosuperior calcaneus. Radiographic measurements are not sensitive or specific for diagnosing Haglund's deformity. Localization of a bone deformity and tendinopathy in the same sagittal section of a magnetic resonance imaging scan can assist with the diagnosis in equivocal cases. The aim of the present cross-sectional study was to determine the prevalence of Haglund's syndrome in patients presenting with Achilles tendinopathy and note any associated findings to determine the criteria for a diagnosis of Haglund's syndrome...

Posterior heel pain is a common condition of the foot and ankle and is seen in a variety of foot types. Nonoperative treatment methods consisting of shoes inserts, heel lifts, stretching, physical therapy, nonsteroidal antiinflammatory drugs, eccentric strength training, and other modalities have been shown to have mixed results. When indicated, surgical repair can produce good long-term results. Complications, although uncommon, most commonly result from wound healing complications.

Noninsertional Achilles tendinopathy often responds to nonoperative treatment. When nonoperative treatment fails, the clinician must distinguish between paratendinopathy and noninsertional tendinopathy. In paratendinopathy, myofibroblasts synthesize collagen, causing adhesions, and the paratenon may be released or excised. If a core area of tendinopathy is identified on MRI, the area is excised longitudinally and repaired with a side-to-side suture. If greater than 50% of the tendon diameter is excised, the authors recommend a short flexor hallucis longus tendon transfer with an interference screw...

Midsubstance Achilles tendinopathy is one of the most common lower leg conditions. Most patients can recover with nonsurgical treatment that focuses on tendon loading exercises and, when necessary, symptom modulating treatments such as topical, oral, or injected medication, ice, shoe inserts, manual therapy, stretching, taping, or low-level laser. If unresponsive to initial management, a small percentage of patients may consider shockwave or sclerosing treatment and possibly surgery.

The term tendinopathy includes a series of pathologies, all of which have a combination of pain, swelling, and impaired performance. The terms tendinosis, tendinitis and peritendinitis are all within the main heading of tendinopathy; this terminology provides a more accurate understanding of the condition and highlights the uniformity of clinical findings while distinguishing the individual histopathological findings of each condition. Understanding the clinical features and the underlying histopathology leads to a more accurate clinical diagnosis and subsequent treatment selection...
