Chronic midportion Achilles tendinopathy: an update on research and treatment.

Chronic painful midportion Achilles tendinosis has been known as a difficult condition to treat, and surgical treatment was often needed. In recent scientific studies, however, treatment with painful eccentric calf muscle training has shown very good short-term clinical results and significantly reduced the need for surgical treatment. Also, very recently, a new method consisting of sclerosing of neovessels in the area with painful tendinosis showed promising short-term results. Ongoing and future research will evaluate the potential of these treatment models.
