The outcomes selected included the Visual Analog Scale (VAS) score, the Harris Hip Score (HHS), the Western Ontario, and McMaster Universities Osteoarthritis Index (WOMAC) and its relevant subscores. A standardized mean difference (SMD) was used as the combined effect size, and a random\u2010effects model was applied for analysis. The magnitude of the effect size was interpreted according to Jacob Cohen\u2019s criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of seven studies involving 465 patients were included. The meta\u2010analysis results indicated that in terms of pain relief, the PRP group showed a statistically significant advantage in VAS scores at 6\u2009months (SMD\u2009=\u2009\u22120.38 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.01). Subgroup analysis revealed that LP\u2010PRP yielded significant improvement (SMD\u2009=\u2009\u22120.32 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.02), whereas LR\u2010PRP did not (SMD\u2009=\u2009\u22120.46 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.18). Similarly, multiple injections (SMD\u2009=\u2009\u22120.43 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.02) demonstrated superiority compared to a single injection (SMD\u2009=\u2009\u22120.12 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.63).Regarding WOMAC\u2010pain scores, the PRP group exhibited statistical differences at 6\u2009months (SMD\u2009=\u2009\u22120.45 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0006) and 12\u2009months (SMD\u2009=\u2009\u22120.36 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.03). In terms of functional impairment, no significant differences were found in the HHS (SMD\u2009=\u20090.13 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.64) or WOMAC subscores (WOMAC\u2010stiffness: SMD\u2009=\u20090.01 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.97 and WOMAC\u2010function: SMD\u2009=\u2009\u22120.24 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.06) at any follow\u2010up time point. However, the WOMAC total score indicated that the overall health status of patients in the PRP group was superior to that in the HA group after treatment (SMD\u2009=\u2009\u22120.42 and\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.009).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The findings of this study indicate that compared with HA, PRP demonstrates a statistically significant advantage in alleviating pain (VAS and WOMAC\u2010pain) and improving overall symptoms (WOMAC total score) in patients with hip osteoarthritis (HOA) although the effect size was found to be moderate. However, regarding the improvement of joint function (HHS and WOMAC\u2010function), no significant differences were observed between the two groups. In summary, while PRP presents a statistical benefit over HA in the treatment of HOA, the effect size is limited; therefore, further high\u2010quality studies are warranted to definitively confirm its clinical superiority.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/prm\/6521682","type":"journal-article","created":{"date-parts":[[2026,6,13]],"date-time":"2026-06-13T08:30:14Z","timestamp":1781339414000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Clinical Efficiency and Safety Between Intra\u2010Articular Injection of Platelet\u2010Rich Plasma and Hyaluronic Acid for Hip Osteoarthritis: A Systematic Review and Meta\u2010Analysis"],"prefix":"10.1155","volume":"2026","author":[{"given":"Di","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shen Hong","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"He Ling","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiao Hua","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8648-5649","authenticated-orcid":false,"given":"Weisheng","family":"Zhuang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,13]]},"reference":[{"key":"e_1_2_14_1_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.332.7542.639"},{"key":"e_1_2_14_2_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-133-8-200010170-00016"},{"key":"e_1_2_14_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11427-014-4673-7"},{"key":"e_1_2_14_4_2","doi-asserted-by":"crossref","first-page":"S71","DOI":"10.1007\/s00198-016-3518-6","article-title":"World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (WCO-IOF-ESCEO 2016): Meet-the-Expert Sessions","volume":"27","author":"Kvien T.","year":"2016","journal-title":"Osteoporosis International"},{"key":"e_1_2_14_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/acr.21596"},{"key":"e_1_2_14_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2004.028886"},{"key":"e_1_2_14_7_2","doi-asserted-by":"publisher","DOI":"10.5301\/hipint.5000184"},{"key":"e_1_2_14_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00590-025-04292-7"},{"key":"e_1_2_14_9_2","first-page":"87","article-title":"Managing Joint Pain in Osteoarthritis: Safety and Efficacy of Hylan GF 20","author":"Conduah A.
