Conservative management of tendinopathy: an evidence-based approach.

Tendinopathy is one of the most frequent overuse injuries associated with sport. It is a failure of a chronic healing response associated with both chronic overloaded and unloaded states. Although several conservative therapeutic options have been proposed, very few of them are supported by randomized controlled trials. Eccentric exercises provide excellent clinical results both in athletic and sedentary patients, with no reported adverse effects. Combining eccentric loading and low-energy shock wave therapy produces higher success rates compared with eccentric training alone or shock wave therapy alone. High-volume injection of normal saline solution, corticosteroids, or anesthetics can reduce pain and improve long-term function in patients with Achilles or patellar tendinopathy. The use of injectable substances such as platelet-rich plasma, autologous blood, polidocanol, and corticosteroids in and around tendons is not support by strong clinical evidence. Further randomized controlled trials are necessary to define the best conservative management of tendinopathy.
