Astym therapy: a systematic review.

Ann Transl Med 2019 Feb;7(4):70

Department of Orthopaedic Surgery, Lenox Hill Hospital, New York, NY, USA.

Soft tissue dysfunction can result from the degeneration of tissues as in the case of degenerative tendinopathy or from the build-up of problematic scar tissue, which can be the result of several aggravating factors, including overuse injuries, acute or chronic trauma, or as a result of surgery. This dysfunction often results in impaired movement, pain, and swelling of the affected area, which can lead to patient dissatisfaction and a lower quality of life. These soft tissue dysfunctions also have a marked economic impact. Read More

Biomechanical evaluation of two methods of fixation of a flexor hallucis longus tendon graft.

Bone Joint J 2018 09;100-B(9):1175-1181

Department of Orthopedics and Trauma Surgery, Medical University of Vienna, Vienna, Austria.

Aims: The traditional transosseus flexor hallucis longus (FHL) tendon transfer for patients with Achilles tendinopathy requires two incisions to harvest a long tendon graft. The use of a bio-tenodesis screw enables a short graft to be used and is less invasive, but lacks supporting evidence about its biomechanical behaviour. We aimed, in this study, to compare the strength of the traditional transosseus tendon-to-tendon fixation with tendon-to-bone fixation using a tenodesis screw, in cyclical loading and ultimate load testing.

Fc receptor-like 3 (-169T>C) polymorphism increases the risk of tendinopathy in volleyball athletes: a case control study.

BMC Med Genet 2018 07 18;19(1):119. Epub 2018 Jul 18.

Research Division, National Institute of Traumatology and Orthopaedics, Avenida Brasil, 500, Rio de Janeiro, RJ, 20940-070, Brazil.

Background: Tendinopathy pathogenesis is associated with inflammation. Regulatory T (Treg) cells contribute to early tissue repair through an anti-inflammatory action, with the forkhead box P3 (FOXP3) transcription factor being essential for Treg function, and the FC-receptor-like 3 (FCRL3) possibly negatively regulating Treg function. FCRL3 -169T>C and FOXP3 -2383C>T polymorphisms are located near elements that regulate respective genes expression, thus it was deemed relevant to evaluate these polymorphisms as risk factors for tendinopathy development in athletes.

Development 2018 08 10;145(15). Epub 2018 Aug 10.

Endocrine Unit, Massachusetts General Hospital, Boston, MA 02114, USA

The bone tendon attachment site known as the enthesis comprises a transitional zone between bone and tendon, and plays an important role in enabling movement at this site. X-linked hypophosphatemia (XLH) is characterized by impaired activation of vitamin D, elevated serum FGF23 levels and low serum phosphate levels, which impair bone mineralization. Paradoxically, an important complication of XLH is mineralization of the enthesis (enthesopathy). Read More

Non-uniformity in pre-insertional Achilles tendon is not influenced by changing knee angle during isometric contractions.

Scand J Med Sci Sports 2018 Nov 25;28(11):2322-2329. Epub 2018 Jun 25.

Department of Development & Regeneration, KU Leuven, Leuven, Belgium.

Achilles tendinopathy remains a prevalent condition among recreational and high-level athletes. Mechanical loading has become the gold standard in managing these injuries, but exercises are often generic and prescribed in a "one-size-fits-all" principle. The aim of this study was to evaluate the impact of knee angle changes and different levels of force production on the non-uniform behavior in the Achilles tendon during isometric contractions.

Is heavy eccentric calf training superior to wait-and-see, sham rehabilitation, traditional physiotherapy and other exercise interventions for pain and function in mid-portion Achilles tendinopathy?

Syst Rev 2018 04 13;7(1):58. Epub 2018 Apr 13.

School of Physiotherapy, The University of Notre Dame Australia, 19 Mouat Street, PO Box 1225, Fremantle, Western Australia, 6959, Australia.

Background: Mid-portion Achilles tendinopathy (AT) is prevalent amongst athletic and non-athletic populations with pain, stiffness and impaired function typically reported. While different management options exist, loading protocols remain the best available intervention and have been shown to be effective in the management of AT. Trials investigating loading in AT have used a variety of different protocols, and recent narrative reviews suggest that no protocol is superior to another when comparing outcomes in pain and function.

Carbon-14 bomb pulse dating shows that tendinopathy is preceded by years of abnormally high collagen turnover.

FASEB J 2018 09 23;32(9):4763-4775. Epub 2018 Mar 23.

Department of Orthopedic Surgery M, Institute of Sports Medicine Copenhagen, Bispebjerg Hospital, University of Copenhagen, Copenhagen, Denmark.

Tendons are essential weight-bearing structures that are often affected by tendinopathy, which leads to pain and impaired mobility. In healthy Achilles tendons, no significant renewal of the weight-bearing collagen matrix seems to occur during adult life, but tendinopathy may lead to increased turnover. The carbon-14 ([C]) bomb pulse method was used to measure lifelong replacement rates of collagen in tendinopathic and healthy Achilles tendons (tendinopathic: n = 25, born 1937-1972. Read More
