Comparison of 2 Methods of Local Anesthetic-Based Injection as Part of a Multimodal Approach to Pain Management After Total Knee Arthroplasty

Abstract: The use of IOPA injections containing ropivacaine, epinephrine, ketorolac, and clonidine during TKA offered some benefit over IOIA infusions containing 0.25% to 0.5% bupivacaine at our institution.

“…PAI group showed a statistically significant reduction in postoperative VAS pain scores in a previous study [17], which positively correlated with NRS pain scores in our study [26]. In a retrospective study [27], Tietje demonstrated that patients receiving PAI of local anaesthetics in TKA had a noticeable decrease in length of hospital stay and incidence of postoperative nausea and vomiting when compared to patients receiving IAI. In the early period after surgery, it is pain that mainly accounts for patients hospitalization [2].…”

“…These injections have been effective in reducing pain and speeding recovery. 4 A study comparing intraarticular injections of 0.25% to 0.50% bupivacaine with periarticular injections of ropivacaine, ketorolac, epinephrine, and clonidine found a significant decrease in hospital length of stay and postoperative nausea and vomiting compared with intraarticular injections. 4…”

“…These injections are widely considered to be safe and effective for reducing postoperative opioid requirements and decreasing time to recov-ery through early mobilization. [1][2][3][4] As with any injection, there exists the potential for injury to the local vascular structures. Among the potential complications is the possibility of forming an arteriovenous fistula as a result of puncture of an artery and vein in close proximity.…”

“…T otal knee arthroplasty (TKA) is performed with the goals to restore mobility, return an individual to activities of daily living, and improve quality of life. 1 However, a substantial number of patients experience severe pain following a TKA, and management of the pain represents a significant clinical problem. 2 Nearly 80% of patients undergoing surgery report moderate to extreme pain in the first 2 weeks following surgery.…”

“…The efficacy and safety of an intraoperative periarticular (IOPA) injection approach containing several different combinations of ropivacaine hydrochloride, ketorolac tromethamine, epinephrine, and clonidine has been established. [1][2][3][4][5][6][7] However, there is no single recommended protocol for periarticular injections, and the analgesics incorporated, doses used, and administration techniques are variable. 3 The purpose of the present study was to compare the effectiveness and safety of liposomal bupivacaine with an IOPA injection following TKA.…”
