Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is estimated that nearly 27 million US adults have osteoarthritis (OA) and suffer from pain . Pulsed Radio Frequency (PRF) is one method that has been successfully used in treatment of various etiologies of pain. However there are limited studies and research that prove its effectiveness in treating articular pain. The proposed study's primary aim is determining if PRF is an effective treatment for chronic osteoarthritic knee pain. This study hypothesizes that PRF has analgesic properties immediately after treatment and at least 3 months afterwards compared to control treatment with physical therapy.

Additionally this research project addresses several other objectives including:

1. Provide a controlled study to determine the effectiveness of PRF for intra-articular pain
2. Determine how effective PRF is 1 month and 3 months after treatment for articular pain.
3. Further scientific evidence on the overall effectiveness of PRF
4. Provide evidence that PRF likely has other mechanism of action besides direct nerve stimulation of inhibitory pain pathways.
5. Compare the effectiveness of PRF vs Physical Therapy in treating chronic knee osteoarthritis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pulsed Radiofrequency

Pulsed Radiofrequency This group will receive one dose of intra-articular PRF in the affected knee using previous literature standards. This includes standard blood pressure monitoring, sterile preparation, and needle insertion of the PRF probe directed at the site of maximal pain. The RFG-3C Plus radiofrequency generator will be activated at 42C, pulse width 10ms, and 2Hz frequency for 15 min.

Group Type EXPERIMENTAL

Percutaneous Pulsed Radiofrequency

Intervention Type DEVICE

Pulsed Radiofrequency

Physical Therapy

This group will receive standard of care outpatient physical therapy weekly for 3-4 weeks with therapist instructions to reduce knee pain.
