“…Since muscle is poorly perfused during contraction [10,22,34,37], arterial blood flow to the vascular bed in the tendon takes place mainly during relaxation. The bed is situated in the interfascicular connective tissue running parallel to the axis of the tendon and forming cross anastomoses [8,9].…”

Thirty patients with ruptures of the Achilles tendon were studied. There were 21 men and 9 women with an average age of 36 years. Specimens from the tendon and paratenon in 24 were examined histologically. Tissue samples of 20 were studied by electron microscopy. Marked degenerative, obliterative and/or inflammatory vascular changes were found in all the ruptured tendons and their paratenon. Our findings indicate that poor vascularity play a role in the aetiology of rupture of the Achilles tendon.

The Xenon133 washout technique was used to measure the blood-flow rate in flexor tendons of rabbits in different conditions. No variation was found with age. On the other hand, activity caused by electrical stimulation of the muscle increased the flow rate in the tendon significantly, confirming that the tendon is a metabolically active structure. Ligation of the vessels to the tendons failed to achieve a decrease of the blood flow rate. This was probably due to a rapid revascularization or biochemical modification of the tissue.
