Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Injection of Platelet Rich Plasma into knee
3 injections 1 week apart.
• Group 1 receives 3 placebo injections (Normal Saline).
• Group 2 receives one PRP injection followed by two placebo injections.
• Group 3 receives 3 PRP injections.

Irrespective of which group a patient is randomised to, they will require a blood draw of 20mL at each of the first 3 appointments to ensure patients are blinded to the treatment. If they are to receive a PRP injection, this will be processed and injected. If they are to receive a saline injection, the blood will be appropriately discarded. The blood draw and preparation will be performed by a doctor who is an unblinded member of the research team. In order to completely blind the patients to their treatment, a shield will be applied so they cannot see what product is being injected.
The blood for PRP is drawn up in a special syringe which is then placed in a centrifuge. The platelet rich plasma component is kept and the other layers discarded. The injection into the knee occurs immediately after centrifuge process (no storage required). .

Efficacy
Statistical methods / analysis
Primary and secondary outcome analysis: In order to compare the relative change in mean outcome measure values in the three treatment groups, the means at baseline and each assessment point will be estimated using repeated measures mixed effects linear regression, corrected for the precise numbers of days at each assessment point (as a random effect). Unadjusted estimates, will be made, and also estimates adjusted for potential confounding variables.
