Pain in the tendon, especially in the Achilles and the patellar tendon, known as tendinopathy, is very common among individuals who play football either competitively or as a hobby. Tendon disorders can also occur in physically inactive individuals. As a result, it appears that physical activity is not always directly associated to histopathology and that physical exercise may be more important for provoking the symptoms than for being the cause of the injury.
The nomenclature used for chronic pain in the tendon is confusing. Until recently, chronic Achilles and patellar pain was thought to involve inflammation and the term “tendinitis” was widely used. Histological studies have since shown that there are no signs of prostaglandin inflammation and, as a result, the term “tendinopathy” is now used to describe a painful tendon. Inflammation of the outer casing of the tendon (the para tendon) can however occur and is called para-tendinitis.
Tendinopathies are not an easy pathology to treat. At present, there are many theories that have sought to explain the origin of the pain. It has been demonstrated that conservational treatment using eccentric exercises (with or without pain) offers very good results in the short and medium term in tendinosis patients. There are also a wide range of other treatment described in the literature
