Trial Title: Study to Evaluate Iovera®° in Adult Patients Undergoing Total Knee Arthroplasty

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Male or female, at least 22 years of age at screening.~2. Scheduled to undergo primary, unilateral, tricompartmental TKA under spinal anesthesia.~3. Primary indication for TKA is degenerative osteoarthritis of the knee.~4. American Society of Anesthesiologists (ASA) physical status 1, 2, or 3.~5. Anticipation of discharge to home after inpatient acute postsurgical phase based on age, comorbidities, home environment, social support, and the judgment of the Investigator.~6. Females of childbearing potential must have a negative pregnancy test result prior to enrollment and agree to use a highly effective method of birth control during the study. A highly effective method of birth control is defined as one which results in a low failure rate (less than 1% per year). Post-menopausal or surgically sterile females would not require a pregnancy test.~7. Able to provide informed consent, adhere to the study visit schedule, and complete all study assessments.~Exclusion Criteria:~1. History of prior contralateral TKA within 6 months or open knee surgery on the knee being considered for TKA. Prior arthroscopy is permitted.~2. Planned concurrent surgical procedure (e.g., bilateral TKA) or planned additional surgery within 90 days of study surgery.~3. Undergoing unicompartmental TKA or revision TKA.~4. Concurrent painful physical condition that may require analgesic treatment (such as an NSAID or opioid) in the postsurgical period for pain that is not strictly related to the knee surgery and which may confound the postsurgical assessments (e.g., significant pain from other joints including the non-index knee joint, chronic neuropathic pain, concurrent or prior contralateral TKA, concurrent foot surgery).~5. Comorbidity that, in the judgment of the Investigator, may affect the subject's ability to participate in the study and postsurgical rehabilitation.~6. Allergy, hypersensitivity, intolerance, or contraindication to any of the study medications (i.e., bupivacaine, lidocaine, acetaminophen, tranexamic acid, celecoxib, naproxen, meloxicam).~7. Use of any of the following medications within the times specified before TKA: long-acting and short-acting opioid medications within 6 weeks; or NSAIDs (except for low-dose aspirin used for cardioprotection) within 3 days or 5 elimination half-lives, whichever is longer.~8. Initiation of treatment with any of the following medications within 1 month prior to the screening visit or ongoing concomitant use if the medication(s) are being given to control pain: selective serotonin reuptake inhibitors (SSRIs), selective norepinephrine reuptake inhibitors (SNRIs), gabapentin, or duloxetine (Cymbalta®). If a subject is taking one of these medications for a reason other than pain control, he or she must be on a stable dose for at least 1 month prior to screening visit.~9. Current use of systemic glucocorticosteroids within 1 month prior to screening in this study, intra-articular corticosteroid injections within 6 weeks, or Zilretta within 3 months.~10. History of coronary or vascular stent placed within the past 6 months (may be extended to 1 year if medically indicated per physician discretion).~11. Have been treated for a deep vein thrombosis, pulmonary embolism, myocardial infarction, or ischemic stroke within the past 6 months (may be extended to 1 year if medically indicated per physician discretion).~12. Any clotting disorder and/or use of an anticoagulant (e.g. warfarin, clopidogrel, etc.) within seven (7) days prior to administration of ioveraº treatment.~13. Rheumatoid or inflammatory arthritis.~14. History of severely impaired renal or hepatic function (in the judgment of the investigator).~15. Any neurologic or psychiatric disorder that might affect postsurgical pain or interfere with study assessments.~16. Malignancy in the last 2 years, per physician discretion.~17. History of misuse, abuse, or dependence on opioid analgesics, other prescription drugs, illicit drugs, or alcohol within the past 2 years.~18. Use of marijuana, including medical use, within 6 weeks prior to screening visit or continuation thereafter.~19. Body weight \<50 kg (110 pounds) or a body mass index \>40 kg/m2.~20. Previous iovera° treatment.~21. Greater than 15° malalignment (varus or valgus) on presurgical radiograph.~22. Prior surgery in the treatment areas that may have altered the anatomy of nerves intended to be treated with the ioveraº system or result in scar tissue in the treatment area.~23. Open and/or infected wounds at or near the treatment site.~24. Any other local skin condition at the treatment sites that in the Investigator's judgment would adversely affect treatment or outcomes.~25. History of cryoglobulinemia.~26. History of paroxysmal cold hemoglobinuria.~27. History of cold urticaria.~28. History of Raynaud's disease.~29. Administration of an investigational product within 30 days or 5 elimination half-lives of such investigational drug, whichever is longer, prior to screening, or planned administration of another investigational product or procedure during the subject's participation in this study~Given the COVID-19 pandemic, the subject must be medically fit/cleared for surgery by the investigator. If there is a concern about a subject's recent or potential exposure to COVID-19, or if the subject is not medically fit/cleared for surgery due to suspected COVID-19 illness/symptoms (or other serious illness), the subject must be excluded per Exclusion criterion #5.
