Outcome Measures
Primary Outcomes (1)
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.

Interventions
Eligibility Criteria
You may qualify if:
- years of age
- American College of Rheumatology (ACR) criteria for osteoarthritis of the knee. This includes radiographic evidence of osteophytes and at least one of the following: age ≥ 50 years old, morning stiffness ≤ 30 minute duration or crepitus on motion.
- Grade II or III osteoarthritis of the knee as determined by Kellgren-Lawrence classification grading scale on anteroposterior (AP) x-ray within previous 6 months.
- Participants are ambulatory without assistive devices.
- Knee pain of ≥ 40 mm on Visual Analog Scale (VAS) when performing one of two movements that elicit the worst pain: standing from a seated position or walking up/down stairs.
- Participant reports knee pain in the anterior and/or inferior aspect of the knee as documented on the knee pain map in the appropriate areas.
- A diagnostic lidocaine (without epinephrine) block of the infrapatellar branch of the saphenous nerve results in a 50% reduction in the VAS pain assessment score when performing the activity that elicits the worst pain: standing from a seated position or walking up/down stairs.
- Participant is able to tolerate a washout of prescription and over-the-counter pain relief for a duration of 5 times the half-life of the medication prior to the Baseline visit.
- Participant is able to tolerate a washout of adjunctive therapies for knee pain for 72 hours prior to the Baseline visit.
- Western Ontario and McMaster Osteoarthritis Index (WOMAC) NRS3.1 Pain subscore ≥ 20 at Baseline/Visit 2.
- Participant is able to tolerate discontinuation of all pain medication throughout the duration of the study. Acetaminophen may be used as rescue medication with a maximum dose of 4g per day.
- Participant is able to tolerate discontinuation of rescue medication, acetaminophen, for 24 hours prior to all follow-up visits.
- Prescription and over-the-counter pain medications must be maintained on a stable schedule for at least two weeks prior to screening.
- Participant is willing and able to give written informed consent.
- Participant is willing and able to comply with study instructions and commit to all follow-up visits for the duration of the study.
- +1 more criteria
You may not qualify if:
- History of a partial or full knee replacement of the knee to be treated.
- Planned partial or full knee replacement within the next 12 months in knee to be treated.
- Previous myoscience Focused Cold Therapy\^TM (FCTTM) treatment.
- Viscosupplementation within the previous 6 months in knee to be treated.
- Participant reports the majority of knee pain outside of the anterior/inferior aspect of the knee.
- Intra-articular steroid injection in the knee to be treated within previous 3 months.
- Gross deformity of the knee including varus or valgus.
- Started physical therapy of the knee to be treated within 3 months of screening.
- Received acupuncture for knee pain within 3 months prior to screening.
- Body Mass Index ≥ 35.
- Prior surgery in the treatment area that may alter the anatomy of the infrapatellar branch of the saphenous nerve or result in scar tissue in the treatment area.
- Open and/or infected wound in the treatment area.
- Disease of the spine, hip, contralateral knee or other lower extremity joint of sufficient degree affecting the assessment of the treated knee.
- Acetaminophen intolerance or allergy.
- Allergy to lidocaine.
