A Multicenter, Double-blind, Randomized, Sham-controlled Study Assessing Opioid Utilization, Postoperative Pain and Function in Subjects Undergoing Total Knee Arthroplasty Treated With Presurgical Iovera®° or Sham Iovera®° Cryoneurolysis and Postsurgical Multimodal Pain Regimen
Primary objective: The primary objective of this study is to evaluate postsurgical pain control, after presurgical iovera° treatment plus EXPAREL® and standardized multimodal therapy compared with presurgical sham iovera° treatment plus EXPAREL and standardized multimodal therapy in subjects undergoing primary unilateral total knee arthroplasty (TKA). Secondary objectives: The secondary objectives of this study are to compare postsurgical pain control or postsurgical total opioid consumption, opioid-free status, physical function, sleep quality, and safety of presurgical iovera° treatment plus EXPAREL and standardized multimodal therapy with presurgical sham iovera° treatment plus EXPAREL and standardized multimodal therapy, in subjects undergoing primary unilateral TKA
• Male or female, at least 22 years of age at screening.
• Scheduled to undergo primary, unilateral, tricompartmental TKA under spinal anesthesia.
• Primary indication for TKA is degenerative osteoarthritis of the knee.
• American Society of Anesthesiologists (ASA) physical status 1, 2, or 3.
• Anticipation of discharge to home after inpatient acute postsurgical phase based on age, comorbidities, home environment, social support, and the judgment of the Investigator.
• 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.
• Able to provide informed consent, adhere to the study visit schedule, and complete all study assessments.
