Current Practices and Perceived Effectiveness of Clinicians Regarding Polynucleotide Injection for Knee Osteoarthritis: A Survey-Based Evaluation
Open accessAbstract
Aims: Intra-articular (IA) injection therapy, particularly IA hyaluronic acid (HA), is a common treatment for knee osteoarthritis, but it does have limitations. The injection of IA polynucleotide (PN) has emerged as an alternative, potentially offering superior clinical outcomes. This study investigates current practice patterns and the perceived effectiveness of PN among clinicians for treating knee osteoarthritis in the Republic of Korea. Methods: Based on a survey conducted among clinicians who use PN in clinical practice, we explored the current practices and assessed the perceived effectiveness of IA PN in treating knee osteoarthritis. Results: A total of 265 clinicians who used IA PN for knee osteoarthritis participated in the survey. Most clinicians (73.3%) used PN therapy for the treatment of chronic pain, with varying administration frequencies. In addition, 25.8% of clinicians used PN for the treatment of acute flare-ups. In cases of knee effusion, 55.5% of clinicians removed the effusion prior to administering PN. Clinicians rated PN as more effective than HA for both chronic pain and acute flare-ups, with higher scores for cushioning, anti-inflammatory effects, and delaying joint degeneration. The clinicians stated that patients expressed a higher satisfaction with IA PN compared with IA HA, noting improvement in joint smoothness, noise reduction, pain relief, and a reduction in heat sensation and swelling. Conclusions: The results of the present study highlight the extensive use and perceived benefits among clinicians of IA PN for knee osteoarthritis in the Republic of Korea. Further research is warranted to explore the effectiveness of PN in acute flare-ups and to validate these findings in broader populations.

PN has shown favorable outcomes in improving knee function and alleviating pain without causing serious adverse effects.
“In addition, PN has shown favorable outcomes in improving knee function and alleviating pain without causing serious adverse effects [42,43,44,45,46,47].”
From Comparison of Polynucleotide and Polydeoxyribonucleotide in Dermatology: Molecular Mechanisms and Clinical Perspectives (2025) · cites this paper as [47]
The Results (§3.3; page unavailable) report clinicians’ ratings of better pain relief and smoother joint movement with PN than with HA. The Discussion (§4; page unavailable) says these are perceived benefits, not measured improvements in knee function, and notes that complications can occur; it does not establish an absence of serious adverse effects.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
