Table 2. Changes in WOMAC and VAS Pain scores at various intervals after PRP injections among the study population.

Repeated measures ANOVA applied for p-values. P-value <0.05 was taken as statistically significant.

WOMAC: Western Ontario and McMaster Universities Arthritis, VAS: Visual Analogue Scale, ANOVA: analysis of variance, PRP: platelet-rich plasma
