It causes substantial pain and loss of function for individuals and leads to important strain on the healthcare program [1]. The knee is the most generally impacted joint, and existing treatment options of OA focus on decreasing pain, increasing function, and improving high quality of life. These therapies, however, fail to effectively resolve the underlying pathophysiological processes involved in OA or regenerate diseased cartilage. This really is among the lots of factors why the field of regenerative medicine and the use of biologics including Ras web UC-derived WJ have grown so swiftly. This trial will likely be one the very first to evaluate the security and efficacy of intraarticular UC-derived WJ with patients with grade II or III knee OA. We anticipate that the intraarticular injection of UC-derived WJ is safe, and participants will show an improvement in their general satisfaction, pain, function, and quality of life. We also hypothesize that cartilage formation over a period of 1 year in comparison with the baseline go to will improve. Constructive outcomes from this study may also lay the foundation to get a massive placebo-controlled trial of intraarticular UCderived WJ for symptomatic knee OA.Abbreviations AEs: Adverse events; ANOVA: Evaluation of variance; CKs: Cytokines; CRFs: Case report forms; EVs: Extracellular vesicles; GFs: Development aspects; HA: Hyaluronic acid; KL: Kellgren-Lawrence scale; KOOS: Knee Injury and Osteoarthritis Outcome Score; MOCART: Magnetic Resonance Observation of Cartilage Repair Tissue; NPRS: Numeric discomfort rating scale; OA: Osteoarthritis; PI: Principal investigator; SANE: Single Assessment Numeric Evaluation; TKR: Total knee replacement; UC-derived WJ: Umbilical cord-derived Wharton’s Jelly Acknowledgements The authors would like thank Dr. Kristin Delfino (Southern Illinois University, School of Medicine, Springfield, IL, USA) for her assistance with statistical analysis section.References 1.
