Pivotal Trial

Summary

This trial found that a single intra-articular injection of triamcinolone acetonide was associated with decreased cartilage breakdown products in the early stages of OA, specifically in patients with higher degrees of synovitis.

Who is the study for?

This trial is for adults aged 40 and over who are scheduled for arthroscopic partial meniscectomy (APM) due to osteoarthritis with evidence of grade 2 chondral change. Participants must be able to give informed consent and follow study requirements. Pregnant or nursing women, those planning pregnancy, recent recipients of knee injections, and individuals with severe OA or hypersensitivity to Zilretta or triamcinolone acetonide cannot participate.

What is being tested?

The trial is testing the effectiveness of an injectable product called Zilretta against a placebo in reducing synovitis-related symptoms after APM surgery. Synovitis is linked to increased symptoms and progression in osteoarthritis patients. The study aims to understand if targeting synovitis can improve outcomes post-surgery.

What are the potential side effects?

Potential side effects may include reactions at the injection site, increased blood sugar levels (especially important for diabetics), immune system suppression leading to higher infection risk, thinning skin around the injection area, adrenal gland problems, cataracts or glaucoma with repeated injections.
