Treatment of midportion Achilles tendinosis: similar clinical results with US and CD-guided surgery outside the tendon and sclerosing polidocanol injections.

Sclerosing polidocanol injections targeting the area with vasculo/neural ingrowth on the ventral side of the tendon have previously been demonstrated to give good clinical results in patients with chronic painful midportion Achilles tendinosis. In this study, 20 consecutive patients (9 men and 11 women, mean age 46 years) with chronic painful midportion Achilles tendinosis were treated with either sclerosing polidocanol injections (Group A) or open surgical revision of the area with vasculo/neural ingrowth on the ventral side of the Achilles tendon (Group B). Before treatment, all patients had structural tendon changes and increased blood flow-neovascularisation demonstrated with US and colour Doppler.
