Chronic Achilles tendon disorders range from overuse syndromes to frank ruptures. Numerous forms of treatment have been used, depending on the nature of the disorder or injury. Ultrasonography and magnetic resonance imaging are commonly used for evaluation. The spectrum of disease comprises paratenonitis, tendinosis, paratenonitis with tendinosis, retrocalcaneal bursitis, insertional tendinosis...

introduction: pain in the achilles tendon during loading is a very common condition. conservative treatments, such as low level laser therapy (lllt) have been reported to give varying results. recently, a new laser treatment technique, high power laser treatment (hplt) (swiss dynalaser®), was introduced in scandinavia, but has not, to our knowledge, been systematically tested before. the object...

BACKGROUND Recalcitrant lateral epicondylitis (elbow tendinosis) is a common cause of elbow pain. There are many forms of treatment, none being superior. HYPOTHESIS The main hypothesis tested in this study is that radiofrequency microtenotomy offers better results than the extensor tendon release and repair operation for elbow tendinosis, especially earlier recovery. STUDY DESIGN Randomized...

Objective: Expansion of the extracellular matrix is a prominent but poorly characterized feature of tendinosis pathology. We aimed to characterize the extent and distribution of the large aggregating proteoglycan versican in patients with patellar tendinosis. Methods: Tendon was obtained from tendinopathy patients undergoing debridement of the patellar tendon and from controls undergoing intram...

The histopathology of tendons with painful tendinopathy is often tendinosis, a fibrosis-like condition of unclear pathogenesis characterized by tissue changes including hypercellularity. The primary tendon cells (tenocytes) have been shown to express adrenoreceptors (mainly alpha-2A) as well as markers of catecholamine production, particularly in tendinosis. It is known that adrenergic stimulat...

BACKGROUND Extensor tendinosis ("tennis elbow") is a degenerative overuse tendinopathy of the wrist extensors at their attachment to the lateral humeral epicondyle. No treatment has been universally successful. Topical application of nitric oxide has been used effectively to treat fractures and cutaneous wounds in animal models, presumably by stimulation of collagen synthesis in fibroblasts. ...

Objective: In this study, in order to establish a more effective therapeutic model for the patients with chronic rotator cuff tendinosis, the authors attempted to compare the therapeutic effects of general physical therapy, eccentric contraction exercise, extracorporeal shock wave therapy (ESWT) and their combination for patients with noncalcific subscapular tendinosis. Methods: 120 patients wi...

BACKGROUND Tenocytes produce substance P (SP), and its receptor (neurokinin-1 receptor (NK-1R)) is expressed throughout the tendon tissue, especially in patients with tendinopathy and tissue changes (tendinosis) including hypercellularity and vascular proliferation. Considering the known effects of SP, one might ask whether SP contributes to these changes. OBJECTIVES To test whether developme...

OBJECTIVE To prospectively investigate tendon thickness and tendon structure by ultrasonography in patients treated with eccentric calf muscle training for painful chronic Achilles tendinosis located at the 2-6 cm level in the tendon. METHODS The patients were examined with grey scale ultrasonography before and 3.8 years (mean) after the 12 week eccentric training regimen. At follow up, a que...
