SEATTLE--(BUSINESS WIRE)--Amp Orthopedics, a privately held medical device company, announced the initiation of a clinical trial in adults with mild-to-moderate knee osteoarthritis (OA) to determine the safety and effectiveness of the company’s non-thermal pulsed radio frequency (PRF) technology to ameliorate pain. The OARS trial is a randomized, sham-controlled, double-blind study of 150 patients utilizing standardized pain indices to measure changes in pain scores and compare pain reduction and duration of clinical benefit between the treated and control groups. The trial utilizes an innovative, Internet-based direct-to-patient recruitment methodology. Results from the trial are anticipated in 2012, and could become the basis for market clearance of the Amp device in the OA pain reduction indication.
