REVIEW
Chunguang Wang, Hao Li, Kang Chen, Bing Wu, Haifeng Liu
It has been reported that the single nucleotide polymorphism (SNP) rs1800012 in COL1A1 might be associated with the susceptibility to sports-related tendon and ligament injuries such as ACL injuries, Achilles tendon injuries, shoulder dislocations and tennis elbow. But the data from different studies have been conflicting. Here we attempted to systematically summarize and clarify the association between the SNP and sports-related tendon and ligament injuries risk. Six eligible studies including 933 cases and 1,381 controls were acquired from PubMed, Web Of Science and Cochrane library databases...

The Achilles is a long tendon varying in cross-sectional area (CSA) considerably along its length. For the same force, a smaller CSA would experience higher tendon stress and we hypothesised that these areas would therefore undergo larger transverse deformations. A novel magnetic resonance imaging-based approach was implemented to quantify changes in tendon CSA from rest along the length of the Achilles tendon under load conditions corresponding to 10, 20 and 30% of isometric plantar flexor maximum voluntary contraction (MVC)...

In clinical practice, chronic Achilles tendon ruptures are uncommon. Usually, these lesions are discovered four to six weeks after injuries. More frequently, Achilles tendon ruptures are acute and treated with tendon sutures.1 Many surgical techniques are available to treat chronic lesions such as sutures or V-Y elongation with or without augments.2-3 Our case is about a chronic Achilles tendon rupture discovered two years after injury. Our patient came to our attention with a 6 cm tendon gap. We performed tendon repair with cadaver allograft...

Kaissar Yammine, Chahine Assi
PURPOSE: Achilles injuries are very common, mainly among young athletes. When indicated, the surgical treatment aims for strong repairs that can resist distraction and consequently ruptures. The majority of the published clinical meta-analyses reported comparisons between broad treatment modalities such as conservative treatment, open, and minimally invasive surgery. METHODS: A meta-analysis has been conducted to assess further clinical and biomechanical variables on human cadavers related to the efficacy of Achilles repair...

Tendinopathy is a common clinical pathology found in athletes and workers with mixed treatment results. Piperine, a major alkaloid found in the black and long pepper, has been demonstrated to have variety of pharmacological properties such as analgesic and anti-inflammatory effects. The present study was designed to investigate the effects of piperine on collagenase-induced Achilles tendon injury. Rats were intratendineously injected with collagenase in the right Achilles tendon, followed by intragastrical administration of piperine (100 mg/kg)...

Tendon is a connective tissue mainly composed of collagen fibers with peculiar mechanical properties essential to functional movements. The increasing incidence of tendon traumatic injuries and ruptures-associated or not with the loss of tissue-falls on the growing interest in the field of tissue engineering and regenerative medicine. The use of animal models is mandatory to deepen the knowledge of the tendon healing response to severe damages or acute transections. Thus, the selection of preclinical models is crucial to ensure a successful translation of effective and safe innovative treatments to the clinical practice...

Metabolic diseases such as diabetes mellitus type-II (DM-II) may increase the risk of suffering painful connective tissue disorders and tendon ruptures. The pathomechanisms, however, by which diabetes adversely affects connective tissue matrix metabolism and regeneration, still need better definition. Our aim was to study the effect of DM-II on expressional changes of neuro- and angiotrophic mediators and receptors in intact and healing Achilles tendon. The right Achilles tendon was transected in 5 male DM-II Goto-Kakizaki (GK) and 4 age-matched Wistar control rats...

Chronic degenerative tendon injuries as well as injuries due to acute high-energy trauma and incisional injuries are a significant aspect in the emergency surgery department. As a result of anatomical characteristics and exposure certain tendons are particularly vulnerable to injury. These include the biceps brachialis, quadriceps femoris, patella, achilles and tibialis anterior tendons. Besides the broad spectrum of non-surgical treatment, surgeons should have knowledge of the various surgical techniques including suturing, anchor refixation and reconstruction techniques...

INTRODUCTION: Ruptures of the Achilles tendon are the most common tendon injuries of the lower extremities. Besides the initial operative or non-operative treatment, rehabilitation of patients plays a crucial role for tendon healing and long-term outcome. As only limited evidence is available for optimized rehabilitation regimen and guidelines for the initial (e.g., first 6 weeks) rehabilitation are limited, this study investigated the current rehabilitation concepts after Achilles tendon rupture...

We report a series of 143 patients who underwent limited open Achilles tendon repair using the Achillon device at a mean follow-up of 25 months. All patients attending our institution with a diagnosis of acute Achilles tendon rupture were considered for operative repair using the Achillon jig unless they declined surgery or met the exclusion criteria. Following surgery patients were contacted and asked to complete an Achilles Tendon Rupture Score (ATRS). The clinical records were reviewed for evidence of complications, demographic information and evidence of re-rupture...

An acute Achilles tendon rupture is the most common tendon rupture of the lower extremities, yet the optimal timing for an early surgical repair is unclear. To identify the optimal time for an early surgical repair with favorable results, we evaluated the isokinetic muscle strength and clinical outcomes of early surgical repairs of acute Achilles tendon ruptures performed at different time points after injury. Between January 2011 and July 2015, a total of 65 patients underwent an acute Achilles tendon rupture repair within 1 week after injury...

Tendons play a critical role in the transmission of forces between muscles and bones, and chronic tendon injuries and diseases are among the leading causes of musculoskeletal disability. Little is known about sex-based differences in tendon structure and function. Our objective was to evaluate the mechanical properties, biochemical composition, transcriptome, and cellular activity of plantarflexor tendons from 4 month old male and female C57BL/6 mice using in vitro biomechanics, mass spectrometry-based proteomics, genome-wide expression profiling, and cell culture techniques...

Unexpected injuries can have a profound effect on a surgeon's performance and thus on patients and surgical departments. Here we describe a technique for performing surgery in the standing position, as done by a surgeon with an Achilles tendon rupture. During his prescribed 45-day non-weight-bearing period for the left ankle after surgery for an Achilles tendon rupture, the surgeon was able to participate in 15 surgeries as an operator or assistant, due to his use of a combination of injured-leg genuflection on a stool and a 'Surgical Body Support' device...

BACKGROUND: The extensile lateral approach (EL) has been associated with increased wound complications such as apical necrosis which may be due partially from violation of the lateral calcaneal artery (LCA). Traditionally, the vertical limb has been placed half-way between the fibula and Achilles tendon, which may be suboptimal given the proximity to the LCA. We hypothesized that placing the vertical limb further posterior (ie, modified EL [MEL]) would increase the distance from the LCA...
