Summary

The aim of this study is to establish if the application of autologous conditioned plasma (ACP), also described as platelet rich plasma (PRP), to the site of supraspinatus tendon repair beginning within two weeks of surgery, can improve patient outcomes over the course of 12 months. These outcomes will be measured by post-surgical pain and function scores, shoulder strength and range of motion (ROM), and radiological parameters of tendon healing. Outcome measures will be compared to a control group of patients receiving placebo injections following surgery (saline plus local anaesthetic). This study is significant for being the first double blind randomised control trial, using two PRP injections to examine the efficacy of a PRP preparation following surgical repair of supraspinatus tendon. The objective is to prolong and enhance the tendon healing response initiated by surgery. The research hypothesis is that enhanced tendon healing following the PRP injections will lead to more rapid rehabilitation and lower rates of re-rupture of the repaired tendon compared to the control group.

Conditions

• Supraspinatus Tear

Interventions

Type	Name	Description
OTHER	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
DRUG	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
