Brief Summary
This study is designed to:
- Determine the effectiveness (primarily measured by pain relief) of Coolief when used to create radiofrequency lesions of the genicular nerves compared to pain relief following corticosteroid injection; and
- Confirm the safety of Coolief when used to perform radiofrequency lesions of the genicular nerves in subjects to manage knee pain compared to safety of corticosteroid injection

Outcome Measures
Primary Outcomes (2)
Numeric Rating Scale (NRS)
The number of subjects whose knee pain is reduced by ≥ 50% based on the Numeric Rating Scale (NRS). The NRS is an 11-point scale (0 points to 10 points), where 0 points equals "no pain" and 10 points equals the "worst pain".
6 months
Safety: Number of Subjects Experiencing Adverse Events Through Final Follow up.
Safety Endpoint: Number of subjects experiencing adverse events through final follow up.
6 months and 12 months
Secondary Outcomes (2)
Numeric Rating Scale
12 months
Oxford Knee Score
6 months and 12 months
Other Outcomes (2)
Subject Satisfaction - Number of Participants With a Global Perceived Effect Score of 5 or Greater
6 months and 12 months
Medication Usage
6 months and 12 months
Study Arms (2)
Cooled radiofrequency
EXPERIMENTALCooled radiofrequency energy will be delivered to study subjects' knees to ablate culprit sensory nerves and reduce knee pain
Corticosteroid injection
ACTIVE COMPARATORCorticosteroid injections will be administered to study subjects' knees to reduce knee pain
Interventions
Delivery of energy to ablate sensory nerves via cooled radiofrequency probe
Delivery of corticosteroid into knee by injection with needle to reduce knee pain
Eligibility Criteria
You may qualify if:
- Age ≥ 21 years
- Able to understand the informed consent form and provide written informed consent and able to complete outcome measures
- History of chronic knee pain for longer than 6 months unresponsive to conservative treatments (PT, oral analgesics, intra-articular injections with steroids and/or viscosupplementation)
- Positive response (defined as a decrease in numeric pain scores of at least 50%) to a geniculate nerve block of the index knee
- Pain on NRS ≥ 6 on a 10 point scale for the index knee
- Radiologic confirmation of osteoarthritis (x-ray/MRI/CT) of OA grade of 2 (mild), 3 (moderate) or 4 (severe) noted within 12 months for the index knee
- Oxford Knee Score group at Baseline of ≤ 35 indicating moderate to severe OA in the index knee
- If the patient is taking an opioid or other morphine equivalent medication, the dose must be considered clinically stable (defined as \<10% change in dosage for ≥ 2 months prior to the screening visit).
- Analgesics including membrane stabilizers such as Neurontin and antidepressants for pain such as Cymbalta must be clinically stable (defined as stable dosage for ≥ 6 weeks prior to the screening visit) and shall not change during the course of the study without approval of investigator. Agree to see one pain doctor (study investigator) for knee pain during the study period
- Index knee pathology that is consistent with generally accepted indications for total knee arthroplasty.
- Willing to delay any surgical intervention for the index knee for 12 months.
- Willingness to provide informed consent and to comply with the requirements of this protocol for the full duration.
You may not qualify if:
- Pseudo arthritis, rheumatoid arthritis or other systemic inflammatory arthritis condition that could cause knee pain.
- Previous or pending lower limb amputation.
- Intra-articular steroid, platelet rich plasma (PRP) or hyaluronic acid injections in the index knee within 90 days from the screening visit.
- An intra-articular corticosteroid injection is not indicated as an appropriate treatment option.
- Prior radiofrequency of the genicular nerves of the index knee.
- Prior partial, resurfacing, or total knee arthroplasty in index knee.
- Clinically significant ligamentous laxity of the index knee.
- Evidence of structural abnormality other than osteoarthritis of knee, hip or back that materially affects gait or function of the knee or is the underlying cause of the knee pain.
- BMI \> 40.
- Extremely thin patients and those with minimal subcutaneous tissue thickness that would not accommodate a lesion of up to 14 mm in diameter to limit the risk of skin burns.
- Pending or active compensation claim, litigation or disability remuneration (secondary gain) related to knee.
- Pregnant or intent of becoming pregnant during the study period.
- Chronic pain associated with significant psychosocial dysfunction.
- Beck's Depression Index score of \> 22 (indicates clinically depressed state).
- Allergies to any of the medications to be used during the procedure.
- +8 more criteria
