Brief Summary:
Chronic achilles tendinopathy is a common disease especially in adults. The golden standard in treatment has up to now been excentric exercises but with varying success. A new hypothesis is that this chronic pain is due to neo vascularisation. In a pilot study sclerosing injections with polidocanol have had a successful efficacy. Our aim is to study the efficacy of polidocanol as a treatment in a randomised controlled setting on a larger scale.

Condition or disease Intervention/treatment Phase
Chronic Achilles Tendinopathy Drug: Aethoxysclerol Phase 4

Detailed Description:
48 patients with chronic achilles tendinopathy for more than 3 months who have tried excentric exercises without success will be randomised to either polidocanol or lidocaine injections if having ultrasound verified neo-vascularisation.
