Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Three intra-fascial PRP injections (2 mL PRP each) guided by ultrasound, by a medial approach following injection of local anaesthetic into the skin, and at weekly intervals.
Three mL of platelet rich plasma will be obtained using a single step centrifugation procedure and XC-2000 laboratory benchtop centrifuge. Twenty five point five mL of autologous blood will be divided equally between three 8.5 mL ACD BD Vacutainer venous blood collection tubes and centrifuged at 2,000 rpm (447 g) for 10 minutes. The lowest 1 mL of the plasma, the platelet rich plasma (PRP), is then harvested from each tube avoiding contamination by the buffy coat and red cell layers. Two mL will be collected for injection into the patient and 1 mL will be collected for laboratory analysis of platelet numbers. Each sample will be ‘activated’ with 0.05 mL calcium chloride 10% per 1 mL plasma.
