• Use of immediate-release opioids for more than 3 days per week within previous month.
• Participant is pregnant or planning to become pregnant while enrolled in the study.
• Current enrollment in any investigational drug or device study or participation within 30 days prior to screening.
• Any additional diagnosis that in the opinion of the Investigator directly contributes to knee pain.
• Any concomitant inflammatory disease or other condition that affects the joints (e.g. rheumatoid arthritis, metabolic bone disease, gout, active infection, etc.)
• Any clotting disorder and/or use of an anticoagulant (e.g., aspirin, warfarin, clopidogrel, etc.) within seven (7) days prior to administration of the device.
• Any local skin condition at the treatment site that in the Investigator's opinion would adversely affect treatment or outcomes.
• Any chronic medical condition that in the Investigator's opinion would prevent adequate participation.
• Any chronic medication use (prescription, over-the-counter, etc.) that in the Investigator's opinion would affect study participation or Subject safety.
• For any reason, in the opinion of the Investigator, the Subject may not be a suitable candidate for study participation (i.e., history of noncompliance, drug dependency, any related knee injury due to a worker's compensation claim, etc.).
• Known liver dysfunction.

Primary	Absolute Change From Baseline in Western Ontario and McMaster Universities Arthritis Index (WOMAC) Pain Subscale Score at Day 30	The WOMAC is a tri-dimensional, disease-specific, patient-reported outcome measure. It consists of 24 questions [each question is presented in a numerical rating scale format with possible values between 0= No (best) to 10= Extreme (worst)] with 5 questions regarding pain [possible subscale score 0 to 50], 2 questions regarding stiffness [possible subscale score 0 to 20] and 17 questions regarding function difficulty [possible subscale score 0 to 170]. A negative change from Baseline indicates improvement. An Analysis of Covariance (ANCOVA) model was used for analyses.	Baseline to Day 30
Secondary	Change From Baseline in Visual Analog Scale (VAS) at Day 30	VAS pain assessment is a measure of pain intensity. The scale is made up of a 10 centimeter (cm) [100 millimeter (mm)] horizontal line. The far left of the horizontal line is labeled "no pain" while the far right of the horizontal line is labeled "worst imaginable pain". A negative change from Baseline indicates improvement. An ANCOVA model was used for analyses.	Baseline to Day 30
Secondary	Change From Baseline in Total WOMAC Score at Day 30	The WOMAC is a tri-dimensional, disease-specific, patient-reported outcome measure. It consists of 24 questions [each question is presented in a numerical rating scale format with possible values between 0= No (best) to 10= Extreme (worst)] with 5 questions regarding pain [possible subscale score 0 to 50], 2 questions regarding stiffness [possible subscale score 0 to 20] and 17 questions regarding function difficulty [possible subscale score 0 to 170]. The WOMAC total score was calculated by summing the 3 subscales for a total possible score of 0 to 240. A negative change from Baseline indicates improvement. An ANCOVA model was used for analyses.	Baseline to Day 30
Secondary	Change From Baseline in VAS at Day 60	VAS pain assessment is a measure of pain intensity. The scale is made up of a 10 cm (100 mm) horizontal line. The far left of the horizontal line is labeled "no pain" while the far right of the horizontal line is labeled "worst imaginable pain". A negative change from Baseline indicates improvement. An ANCOVA model was used for analyses.	Baseline to Day 60
Secondary	WOMAC Pain Score Responder Rate at Day 30	WOMAC Pain Score Responder Rate is defined as the percentage of participants with at least a 30% reduction in the WOMAC pain score at Day 30 compared to Baseline. WOMAC is a tri-dimensional, disease-specific, patient-reported outcome measure. It consists of 24 questions [each question is presented in a numerical rating scale format with possible values between 0= No to 10= Extreme] with the first 5 questions regarding pain [possible subscale score 0 (best) to 50 (worst)].	Day 30
Secondary	VAS Responder Rate at Day 30	VAS Responder Rate is defined as the percentage of participants with at least a 30% reduction in VAS at Day 30 compared to Baseline VAS pain assessment is a measure of pain intensity. The scale is made up of a 10 cm (100 mm) horizontal line. The far left of the horizontal line is labeled "no pain" while the far right of the horizontal line is labeled "worst imaginable pain".	Day 30
Secondary	Change From Baseline in Total WOMAC Score at Day 60	The WOMAC is a tri-dimensional, disease-specific, patient-reported outcome measure.

The WOMAC total score was calculated by summing the 3 subscales for a total possible score of 0 to 240. A negative change from Baseline indicates improvement.	Baseline to Day 60

VAS pain assessment is a measure of pain intensity. The scale is made up of a 10 cm (100 mm) horizontal line. The far left of the horizontal line is labeled "no pain" while the far right of the horizontal line is labeled "worst imaginable pain".	Day 60
Secondary	WOMAC Pain Score Responder Rate at Day 60	WOMAC Pain Score Responder Rate is defined as the percentage of participants with at least a 30% reduction in the WOMAC pain score at Day 60 compared to Baseline.
