Successful Painful Treatment of the Painful Achilles Was the Start for Research Providing New Knowledge about Tendon Pain and New Treatment Methods

Successful treatment with painful eccentric training for patients with chronic painful midportion Achilles tendinosis started research on pain mechanisms involving ultrasound + Doppler investigations and immunohistochemical analyses of tendon tissue specimens. This research has resulted in a better understanding of the pain mechanisms involved in the chronic painful Achilles and patellar tendon, and based on these findings new non tendon-invasive treatment methods beneficial for the patients have been invented. This is a mini review showing the background and research that resulted in the highly successful mini surgical treatments for mid-portion Achilles tendinopathy and proximal patellar tendinopathy.
