PRP: platelet-rich plasma; 1st-3rd: 1st-3rd quartiles; SF-36: the 36-item short form health survey; PF: physical function; BP: bodily pain. # value compares difference from baseline using post hoc test or Wilcoxon signed-rank test. ↑ value indicates significance of overall change over time using the Friedman test.
