Hi Luay A. Naeem ,

I had a quick look into this for you and found a couple of recent trials that have used 'polidocanol' for tendonitis;

Willberg L, Sunding K, Forssblad M, Fahlström M, Alfredson H. Sclerosing polidocanol injections or arthroscopic shaving to treat patellar tendinopathy/jumper's knee? A randomised controlled study. British journal of sports medicine. 2011 Apr 1;45(5):411-5.

Hoksrud AF, Bahr R. Injectable agents derived from or targeting vascularity: has clinical acceptance in managing tendon disorders superseded scientific evidence. J Musculoskelet Neuronal Interact. 2011 Jun 1;11(2):174-84.

I hope this is useful reading material for you!

Kind regards,

MQ
