The pathogenesis of trigger finger has generally been ascribed to primary changes in the first annular ligament. In contrast, we recently found histological changes in the tendons, similar to the findings in Achilles tendinosis. When we looked further for more similarities we found differences in gene expression in the trigger finger tendons in comparison to normal tendons, in a pattern similar...

Different tendons are designed to withstand different mechanical loads in their individual environments. Variable physiologic loading ranges and correspondingly different injury thresholds lead to tendon heterogeneity. Also, tendon heterogeneity is evident when examining how different tendons regulate their response to changes in mechanical loading (over- and under-loading). The response of ten...

Back Ground: Platelet Rich Plasma is now being utilized for patients with tendinosis and arthritis. This treatment option in many instances has replaced the need for surgery. Hypothesis: The purpose of this study was to investigate if Platelet Rich Plasma (PRP) treatment of elbow tendinosis is associated with improved clinical outcomes with respect to pain, function and return to sports/ recrea...

Calcific tendinosis (tendonosis/tendonitis) is a condition which results from the deposition of calcium hydroxyapatite crystals in any tendon of the body. Calcific tendonitis usually presents with pain, which can be exacerbated by prolonged use of the affected tendon. We report a case of calcific tendinosis in the posterior tibialis tendon at the navicular insertion. The pathology is rare in th...

OBJECTIVE To present a form of therapeutic mechanical load, Graston Technique (GT)-an instrument-assisted soft tissue mobilization method) in three case studies including supraspinatus tendinosis, Achilles tendinosis, and plantar fasciosis. METHOD In each case study, case history and functional testing confirmed the presence of a condition characterized by degenerated soft tissue. Each condit...

E d U c a t i o N Think tendinitis and you think pain and burning in the affected area, decreased strength and flexibility, and pain caused by everyday activities. As it turns out, tendinosis is far more often responsible for these symptoms than tendinitis (1,2,3). It is important for health care practitioners to distinguish between these disorders in order to apply the most appropriate treatme...

Key points • Supraspinatus tendinosis is characterized by an enlarged tendon insertion with myxomatous degeneration revealed by fluid intensity on MR imaging, and no inflammatory changes. • Supraspinatus tendinosis in dogs shows identical clinical presentation to the previously recognized calcifying supraspinatus tendinopathy, except the lack of a macroscopic calcified lesion. • The enlarged te...

OBJECTIVES When re-operating patients with midportion Achilles tendinosis, having had a poor effect of ultrasound (US) and Doppler-guided scraping, the author found the involvement of the plantaris tendon to be a likely reason for the poor result. The aim of this study was to investigate the occurrence of a plantaris tendon in close relation to the Achilles tendon in consecutive patients with m...
