The purpose of this study is to compare in a randomized double blinded controlled trial the effect of heavy slow resistance exercises combined with ultrasound guided injections with local anesthetic with or without glucocorticosteroid in patients with achilles tendinopathy.
Achilles tendinopathy is a common and often longlasting condition especially in a sports population. The highest incidence is seen in sports involving running and jumping. As the primary treatment eccentric exercises is recommended and 60-90% will benefit by that. Other studies have shown equal effect of stretching exercises. In a new study heavy slow resistance exercises has proven effective in achilles tendinopathy and the best treatment in lig.patellae tendinopathy. Injection with glucocorticosteroid is often used in the daily clinic, though inflammation is rarely found. Fredberg 2004 found a good short term effect of glucocorticosteroid injection in an RCT, but no effect in the long term, which the investigators explained by an aggressive rehabilitation with running after a few days. Even though 60-90% will benefit from exercises in efficacy studies, a recent pragmatic effectiveness study by Weetke 2015 found that only 26% did benefit from training alone, but if supplemented by need with 1-3 injections of glucocorticosteroid 76% achieved excellent or good result. To our knowledge no randomized clinical trials have investigated the combined effect of training and injections. The hypothesis of this study is, that training and slowly progressive rehabilitation combined with glucocorticosteroid injections will have better effect than the same training and rehabilitation combined with injections of local anesthetic.

Advocate to avoid running and jumping sports for the first 3 months, thereafter slowly progressing to normal sport activity.
Patients are instructed to carry out strengthening exercises for the diseased achilles tendon 3 times a week. Physiotherapist will instruct all patients in these heavy slow resistance exercises. First time one week after the first injection, and then week 3, 6, 10. The patient will register all training on a diary and on an App.
Ultrasound guided injection in Kagers triangle underneath the thickest part of the achilles tendon with 1ml Lidocain 5 mg/ml and 1 ml methylprednisolone 40mg/ml. Injection is given every months until the tendon pain is markedly reduced (VAS morning pain: 0-20, and VAS training pain: 0-40, and Global recovery rating scale (-5 to +5) is +3 to +5 ). (max 3 injections).
