What this trial studies

This clinical trial investigates the safety and efficacy of Metformin in patients with knee osteoarthritis, a chronic condition that significantly impacts mobility and quality of life. Participants aged 30 to 60 with confirmed moderate to severe osteoarthritis will receive either Metformin or Celecoxib to assess improvements in symptoms and joint function. The study aims to provide insights into whether Metformin can alter the disease progression of osteoarthritis, which currently lacks effective long-term treatment options.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 30 to 60 with X-ray confirmed Kellgren-Lawrence grade II or III knee osteoarthritis.

Not a fit: Patients under 30 or over 60 years old, or those with inflammatory arthritis or other significant health issues, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new treatment option that may slow the progression of knee osteoarthritis and improve patient outcomes.

How similar studies have performed: While there have been studies exploring various treatments for osteoarthritis, the specific use of Metformin in this context is novel and has not been extensively tested.
