Design outcomes

Primary

MeasureTime frame
Determination and comparison of the mean pain score (VAS) at 2 weeks and 12 weeks after injection in patients in intervention group A and intervention B-Determination and comparison of the foot functional status (FFI) score at 2 weeks and 12 weeks after injection in patients in intervention group A and intervention B-Determination and comparison of the incidence rate of various possible side effects after injection during follow-up in patients in intervention group A and intervention B-Determination and comparison of the mean pain score (VAS) and foot functional status (FFI) at the beginning of the study in patients in intervention group A and intervention B-Determination and comparison of the distribution of demographic and clinical characteristics at the beginning of the study in patients in intervention group A and intervention B. Timepoint: Change in mean pain intensity score based on the Visual Analogue Scale (VAS) from baseline (before injection) to 2 weeks and 12 weeks after PRP injection in the two peppering and single-point groups. Method of measurement: The Visual Analog Scale (VAS) will be used to assess the severity of patients' pain, and the Foot Function Index (FFI) questionnaire will be used to assess foot function. Scores for both instruments will be collected and recorded through direct patient questionnaires.Visual Analog Scale (VAS): This instrument is used to measure pain severity and is designed based on the Likert scale. In this scale, pain severity is reported as a number from 0 to 10, with 0 indicating complete absence of pain and 10 indicating the most severe pain imaginable.Foot Function Index (FFI): This questionnaire is used to assess the degree of foot dysfunction and consists of 17 questions categorized into three subscales: pain (5 questions), disability (9 questions), and mobility limitation (3 questions). Each question is scored numerically from 0 to 10. The final score for each subscale is calculated from the sum of the scores for i
