BACKGROUND The purpose of this study was to investigate whether uphill treadmill running in rats created histopathological changes within the Achilles tendon consistent with Achilles tendinosis in humans. METHODS Twenty-six mature rats selectively bred for high-capacity running were divided into run and cage control groups. Run group rats ran on a treadmill at a 15° incline for a maximum dura...

Tendinopathy refers to the clinical presentation of activity-related pain, focal tendon tenderness, and intratendinous imaging changes. The underlying pathology was once thought to be due to inflammation ('tendinitis'), but is now considered to predominantly result from degeneration ('tendinosis'). While some progress has been made in understanding tendinosis, the condition remains poorly under...

PURPOSE To evaluate outcomes of radiofrequency coblation for chronic tendinosis of the foot and ankle tendons. METHODS Records of 7 men and 8 women (16 feet) aged 27 to 65 years who underwent radiofrequency coblation for chronic tendinosis (combined with other procedures for other pathology) of the Achilles, posterior tibial, and peroneal tendons were retrospectively reviewed. The visual anal...

Background: Pain in the shoulder is third-most prevalent musculoskeletal pain type. Most frequently involved tendinopathy/tendon tears supraspinatus tendon, followed by a combination of and infraspinatus tendon. At present, gray-scale ultrasound MRI are used to determine tear size, gross morphology, postsurgical tendon repair. However, they unable material characteristics muscle or Aims Objecti...
