Abstract Background Treatment of ruptured Achilles tendons currently constitutes of conservative early functional treatment or surgical treatment either by open or minimal invasive techniques. We hypothesize that an experimental Achilles tendon suture in an animal model significantly deteriorates Achilles tendon microcirculation immediately following suturing. Methods Fifteen Achilles tendons of eight male Wistar rats 275-325 g were included. After preparation of the Achilles tendon with a medial paratendinous approach Achilles tendon microcirculation was assessed using combined Laser-Doppler and .
