The use of intraoperative liposomal bupivacaine (LB) peri-articular injection has been highly debated for total knee arthroplasty (TKA). We evaluated the effect of an institutional-wide discontinuation of intraoperative LB on immediate postoperative pain scores, opioid consumption, and objective functional outcomes. Between July 1, 2019 and November 30, 2019, an institutional policy discontinued use of intraoperative LB, while the volume of non-LB with epinephrine was increased from 40-ml to 60-ml. A historical cohort was derived from patients undergoing TKA between January 1, 2019 and June 30, 2019. All patients received the same opioid sparing protocol, minimizing variability in prescribing habits. No adductor canal blocks/pumps were utilized. Nursing documented verbal rating scale (VRS) pain scores were collected from our electronic data warehouse and averaged per patient per 12-hour interval. Opiate administration events were derived as Morphine Milligram Equivalences (MMEs) per patient per 24-hour interval. To assess immediate postoperative functional status, the validated Activity Measure for Post-Acute Care (AM-PAC) tool was utilized. All time events were calculated relative to TKA completion instant.Introduction
Material and Methods
Patients who undergo total joint arthroplasty (TJA) are at a high risk for the development of thromboembolic complications. The rate at which venous thromboembolism occurs following TJA has been reported to be between 1.3–9.4%. As a result, the utilization of prophylactic therapies is considered standard of care in this patient population. The primary purpose of the current study was to 1) evaluate patient satisfaction with the use of intermittent compression devices 2) evaluate the risk of self-reported falls secondary to the use of these devices following TJA. This is a single institution, prospective study on patients who underwent TJA at an urban, academic orthopedic specialty hospital. Patients were surveyed using an electronic patient rehabilitation application regarding their use and satisfaction with their home intermittent compression devices with a battery and power cord attachment that the patient must wear while using the devices. They were also asked if any falls or near-falls they may have experienced. Surveys were administered on postoperative Day 14, and patients were given 10 days to submit their responses. Using our institutions data warehouse, patient demographics were also collected (Table 1).Introduction
