Tendinitis is inflammation or irritation of a tendon, Tendons transmit the forces of muscle to the skeleton. As such, they are subjected to repeated mechanical loads, which are felt to be a major causative factor in the development of tendinopathy. Pathologic findings include tendon inflammation, mucoid degeneration, and fibrinoid necrosis in tendons. Microtearing and proliferation of fibroblasts have also been reported. However, the exact pathogenesis of tendinopathy is unclear.
During the 25-year study period in Finland, a total of 15 252 patients received surgical treatment for an acute Achilles tendon rupture. The incidence of surgical treatment of acute Achilles tendon rupture in men was 11.1/100 person-years in 1987 and 20.5/100 person-years in 2011. The corresponding figures in women were 2.5/100 person-years in 1987 and 4.2/100 person-years in 2011. The highest rates occurred in 2008 in men and 2007 in women, and since then the decrease has been 42% in men and 55% in women.
Tendinitis may go away over time. If not, the doctor will recommend treatments to reduce pain and inflammation and preserve mobility to prevent disability and recurrence. He may provide a referral to a rheumatologist, an orthopaedic surgeon or a physical therapist for specialized treatment. When properly treated, most tendinitis conditions don’t result in permanent joint damage or disability.
