  Purpose

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.

Primary Outcome Measures:
  • Pain during physical activity which usually causes pain [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Achilles tendon pressure measuring until pain release. [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
  • Pain while resting. [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
  • Patient evaluation of treatment efficacy [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
  • FAOS [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
  • AOFAS [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
  • Number of neo-vascularisation. [ Time Frame: day 0, 1 and 3 months ] [ Designated as safety issue: Yes ]
  • Localisation of the neo-vascularisation [ Time Frame: day 0, 1 and 3 months ] [ Designated as safety issue: No ]

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.
