Study Summary

This trial will test if a new pain treatment, dorsal root ganglion stimulation (DRG-S), can effectively treat arthritic pain of the knee.

Who is the study for?
This trial is for adults over 21 with chronic knee pain due to arthritis, who have tried other treatments like physical therapy and medications without relief. It's for those not suitable or willing to undergo knee surgery, including patients with a history of surgical repair. Participants must have moderate to severe arthritis confirmed by recent scans and significant pain despite past interventions.Check my eligibility
What is being tested?
The study tests if Dorsal Root Ganglion Stimulation (DRG-S) can effectively relieve arthritic knee pain. DRG-S targets specific nerves affected by tissue damage or dysfunction from conditions like trauma or osteoarthritis, aiming to reduce mechanical pain in the knee.See study design
What are the potential side effects?
While the trial description does not list specific side effects, similar procedures may cause discomfort at the stimulation site, infection risk, nerve damage potential, and possible changes in pain sensation.
