Brief Summary
This clinical trial aims to evaluate and compare the efficacy and safety of CartiPRO, an approved intra-articular atelocollagen injection, versus Synovian injection for the relief of knee pain in patients with knee osteoarthritis. The investigational device is administered intra-articularly, with a second injection given 24 weeks after the first dose. Primary and secondary endpoints include changes in pain scores (VAS), functional assessments (WOMAC, SF-36), and safety evaluations over a 36-week period.

Outcome Measures
Primary Outcomes (1)
Change from baseline in 100-mm Weight-Bearing Pain (WBP) Visual Analogue Scale (VAS) score (0-100 mm)
The change from baseline in Weight-Bearing Pain will be assessed using a 100-mm visual analogue scale ranging from 0 mm, no pain, to 100 mm, worst imaginable pain. Higher scores indicate more severe pain.
at week 12 after the first administration
Secondary Outcomes (12)
Change from Baseline in Weight-Bearing Pain Visual Analogue Scale Score (0-100 mm)
at Weeks 2, 4, and 24 after the first administration
Change from Baseline in Western Ontario and McMaster Universities Osteoarthritis Index Total and Subscale Scores
at Weeks 2, 4, 12, and 24 after the first administration
Change from Baseline in 36-Item Short Form Health Survey Domain Scores (SF-36)
at Weeks 2, 4, 12, and 24 after the first administration
Change from Baseline in Rest Pain Visual Analogue Scale Score (0-100 mm)
at Weeks 2, 4, 12, and 24 after the first administration
Change from Baseline in Motion Pain Visual Analogue Scale Score (0-100 mm)
at Weeks 2, 4, 12, and 24 after the first administration
