Statement of the Problem: The aim of this study is to compare the efficacy of Adductor Canal Blocks (ACB) vs. Periarticular Bupivacaine Injections (PAI) for pain management in Total Knee Arthroplasty (TKA). Methodology & Theoretical Orientation: This randomized clinical trial compared outcomes between ACB (15 cc�s of 0.5% bupivacaine), and standardized PAI (50 cc�s of 0.25% bupivacaine) in 40 patients undergoing TKA at one academic institution for 3 surgeons. Patients undergoing unilateral primary total knee arthroplasty with the use of spinal anesthesia were randomized to 1 of 3 groups; Group A: ACB alone, Group B: PAI alone, and Group C: ACB + PAI. The primary outcome in this study was VAS pain scores in the immediate post-operative period. Secondary outcomes included activity level with physical therapy (PT), post-operative narcotic use, and length of hospital stay. This was an interim analysis of the first 40 patients, with an eventual full sample goal of 150 patients. Findings: Total opioid consumption through POD3 was significantly higher for Group A (162 morphine equivalents) compared to Group B (101 morphine equivalents, p=0.02) and Group C (96 morphine equivalents, p=0.01). There was no significant difference in: VAS scores through POD3 (Group A: VAS 3.1, Group B: VAS 2.6, Group C: VAS 2.6); opioid consumption for POD0, POD1, POD2, or POD3; PT activity level for POD0, POD1, POD2, or POD3; total steps taken with PT through POD3 (Group A: 534 steps, Group B: 671 steps, Group C: 634 steps); nor length of hospital stay (Group A: 3.0 day, Group B: 2.4 days, Group C: 2.9 days). Conclusion & Significance: In this interim analysis, there was significantly higher opioid consumption when patients received an ACB without a PAI. Periarticular bupivacaine injections are recommended for perioperative pain control in all patients who undergo a total knee replacement.
