A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multi-center study aims to assess the efficacy of adipose tissue processed with the SyntrFuge™ system in treating knee osteoarthritis. Patients will receive injections of autologous microsized adipose tissue at the treatment sites, compared to standard care. The study focuses on individuals with chronic knee pain and varying grades of osteoarthritis. Participants will be monitored for their response to the treatment over the course of the study.

Why it matters

Potential benefit: If successful, this approach could provide a novel and effective treatment option for patients suffering from knee osteoarthritis.

How similar studies have gone: Other studies have explored similar fat transfer techniques, showing promising results, but this specific approach with the SyntrFuge™ system is relatively novel.
