Abstract
PURPOSE: The aim of our study is to compare the efficacy of adductor canal block (ACB), periarticular local infiltration (PLI) and both combined (ACB + PLI) in multimodal pain management after TKA. METHODS: This is a prospective, randomized controlled double-blinded study undergoing primary unilateral TKA. They were randomized into three groups with fifty patients in each group: ACB alone (30 ml of 0.2% ropivacaine), PLI alone (30 ml 0.5% ropivacaine in 20 ml of normal saline), and both combined (ACB + PLI). The primary outcome studied was pain using visual analog score (VAS) in postoperative days (POD) 1 and 2. The secondary outcomes estimated were the ambulation capacity, the knee range of motion, need for rescue analgesia and length of hospital stay. RESULTS: The mean VAS score was significantly lower at rest and after mobilization in the combined group (3.51 at POD 1, 2.04 at POD 2), compared with either alone group (ACB = 4.70, 2.86 versus PLI = 4.39, 3.41 at POD 1 and 2 respectively after mobilization, p < 0.001). The ambulation capacity (combined = 103.3 steps versus ACB = 98.1 and PLI = 95.2 steps, p = 0.04) and the knee range of motion (arc of motion 106.7 degrees versus ACB = 104.9 and PLI = 102.2 degrees, p = 0.004) were significantly higher in the combined group compared to the other groups. There was no significant difference in the length of stay between the groups (p = 0.12). CONCLUSION: Adductor canal block combined with periarticular local infiltration provides better pain relief, good range of motion, quicker rehabilitation, and reduced opioid consumption. © Indian Orthopaedics Association 2021.
