Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18-70 with chronic knee pain from osteoarthritis who have not responded to conventional treatments.
✕Probably not a fit
Patients with systemic diseases, post-traumatic arthritis, or those who have received recent intra-articular injections may not benefit from this study.

What this trial studies
This clinical trial investigates the effects of autologous bone marrow aspirate concentrate (BMAC) on patient-reported outcomes in individuals suffering from primary knee osteoarthritis. Participants will be randomly assigned to receive either BMAC injections or corticosteroid injections, with a follow-up period of six months to assess the outcomes. The study aims to enroll 100 patients, with 50 in each treatment group, and includes a crossover option for those initially receiving corticosteroids. The trial is designed to provide insights into the efficacy of BMAC compared to traditional corticosteroid therapy.
Why it matters
Potential benefit: If successful, this study could offer a more effective treatment option for patients with knee osteoarthritis, potentially improving their quality of life.
How similar studies have gone: Previous studies have shown promising results with BMAC in treating osteoarthritis, suggesting potential for success in this approach.
