ABSTRACT
PURPOSE: The purpose of this pilot project case series is to describe the use of preoperative cryoneurolysis for 10 patients presenting for total knee arthroplasty (TKA). DESIGN: Descriptive research design. METHODS: Billing codes were used to identify 10 patients who had previously undergone TKA, preoperative cryoneurolysis and physical therapy (PT) at a Midwestern community hospital. Data collected included anesthetic management strategies, multimodal analgesic therapies, postanesthesia care unit pain scores (PACU), pain scores during physical therapy, and achievement of a range of motion during physical therapy. FINDINGS: Nine of 10 patients who received preoperative cryoneurolysis had PACU pain scores of 0 (0-10 scale) up to 90 minutes postoperatively. Pain scores immediately following cryoneurolysis therapy were reduced in all patients reporting pain greater than 0 (1-10 pain scale) before their treatment. Increased active range of motion trends were noted with reports of decreased pain scores during postoperative physical therapy sessions. CONCLUSIONS: This pilot project case series demonstrates potential benefits of using preoperative cryoneurolysis to provide postoperative pain control and aid with physical therapy recovery following TKA.
