"10ml of patient's own venous blood is aspirated.

"10ml of patient's own venous blood is aspirated. The syringe is centrifuged in a proprietary closed unit (Arthrex Medical Company) for 5 minutes. The venous blood sample will be discarded and a placebo (1ml saline + local anaesthetic) is injected to the surrounding tissue, but not into the tendon, under guided ultrasound.~* First injection at approximately 10 days post-operatively~* Second Injection at approximately 21 days post-operatively"
