Summary

"This trial will compare the effects of two different forms of triamcinolone acetonide on blood glucose levels in diabetic patients with knee osteoarthritis. The study will last approximately 4

Who is the study for?
This trial is for people with Type 2 Diabetes (with HbA1C ≤9, not on insulin) and painful knee osteoarthritis. Participants should have a stable management plan for diabetes and meet specific clinical and radiological criteria to confirm their arthritis diagnosis.
What is being tested?
The study compares two treatments: Zilretta (an extended-release steroid injection) versus Kenalog (an immediate-release steroid injection), focusing on how they affect blood sugar levels in diabetic patients with knee osteoarthritis over approximately four months.
What are the potential side effects?
Possible side effects include elevated blood sugar levels, pain at the injection site, allergic reactions, increased risk of infection, changes in appetite, mood swings, and potential impact on adrenal gland function.
