All the infiltration methods had increasing trends and no statistically significant differences were found between them (P=.769). The term that showed the best correlation over time was «prp» with Spearman's correlation =.90, and the term with the highest relative search volume was «growth factors». Prosthetic treatment generated more interest than conservative treatments, where there was more interest in knee replacement than hip replacement (P<.001).
