Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Other interventions - Autologous conditioned plasma (ACP)
Treatment: Drugs - Placebo

Active comparator: Autologous conditioned plasma (ACP) - 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 red blood cells will be discarded, and the supernatant containing ACP (with additional CaCl to activate the ACP and local anaesthetic) is injected into the tendon bone junction and adjacent area under ultrasound guidance. No adverse consequences are anticipated by using the Arthrex ACP injection.

* First injection at approximately 10 days post-operatively
* Second Injection at approximately 21 days post-operatively

Other Names:

Platelet rich plasma (PRP)

Placebo comparator: Placebo - 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 (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


Other interventions: Autologous conditioned plasma (ACP)
10ml of patient's own venous blood is aspirated. ACP (1ml) (extracted from centrifuged venous sample), with additional calcium chloride is then injected into the tendon-bone junction and adjacent area under guided ultrasound.

* First injection at approximately 10 days post-operatively
* Second Injection at approximately 21 days post-operatively

Treatment: Drugs: Placebo
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
