Description of intervention(s) / exposure
The observational study assessed the effectivenes of Platelet Rich Plasma (PRP) on Non-specific Ankle Pain and Knee Osteoarthritis. Pain levels was assessed from baseline (before PRP injection) to 2-3 months after final PRP treatment. This data was collected retrospectively.
In order to prepare a single injection of PRP with supra-physiological platelet concentrations of up to three times normal, 17 mL of blood was collected from the patient’s cubital vein using a 21 G needle to a blood collection tube containing 1 mL of acid citrate, trisodium citrate-22.0g/L and citric acid-8.0g/L. Thus, two PRP tubes were produced, each containing 8.5 mL of blood. the buffy coat and plasma layers (PRP) were collected from the patient’s PRP tubes via an 18 G needle, into a single syringe. The volume of PRP in the syringe ranged from 7-8 mL.
Knee- 7-8ml PRP injection, average of 4 treatments across 6 weeks
Ankle joint- 7-8ml PRP injection, average of 4 treatments across 6 weeks
Ankle Ligament- 5ml PRP injection, average of 3 treatments across 4 weeks
The PRP treatment was administered by a number of general practitioners specialising in musculoskeletal conditions who have been trained in PRP treatment. Administeration was conducted at a number of medical clinics. Pain assessment was carried out 2-3 months following PRP administration.

Outcomes
Primary outcome [1] 323458 0
Pain, assessed by the visual analogue scale consists of an 11 point scale with 0 being 'no pain at all' and 10 being ‘worst imaginable pain.’
Timepoint [1] 323458 0
Baseline (before PRP injection) and within 2-3 months following the participant’s final PRP treatment. The date of the final PRP treatment was noted for each participant and was used as a guide to determine when the 2-3 month follow up would happen.
Secondary outcome [1] 382006 0
Pain was the main outcome measure, no secondary measures
Timepoint [1] 382006 0
None

Statistical methods / analysis
A repeated measures t-test of variance was conducted to assess pain score differences between the baseline visit and approximately 10 weeks following the final visit. An analysis of covariance (ANCOVA) was conducted to determine whether there was a difference in the change in pain between knee and ankle treatments. This analysis was used to control for potential continuous confounder variables such as the number of treatments. Potential confounding variables were assessed using the correlation regression analyses generated in the ANCOVA, with covariates included in the ANCOVA only if they had a significant effect (p < 0.05) on the VAS pain scores.

Summary
Brief summary
Platelet Rich Plasma (PRP) is a preparation of autologous plasma enriched with a platelet concentration above that normally contained in whole blood. PRP can be used to treat orthopaedic conditions including osteoarthritis, bursitis, muscle strain, tendinitis, and tendinosis.
The aim of the present study was to compare the response of knees and ankles following platelet rich plasma (PRP) treatment. It was hypothesised that the application of PRP treatment to non-specific ankle pain cases would result in a significant reduction in self-reported pain.
