Poster 329: Adductor Canal Block versus Adductor Canal Block Plus IPACK Block for Post-Operative Analgesia Following ACL Reconstruction with Bone-Patellar Tendon-Bone Autograft: A Single-Blind, Randomized Controlled Study

Objectives: In an effort to reduce reliance on opioid analgesics, increased emphasis has been placed peripheral nerve blocks for pain control following ACL reconstruction. The commonly used adductor canal block may provide inadequate post-operative analgesia, as it spares sensory function the posterior aspect of knee. This region can be specifically targeted using IPACK (Interspace Between Popliteal Artery and Capsule Posterior Knee) potentially leading improved control. purpose current study was compare clinical outcomes isolated standard versus combined ACB with respect level pain, consumption, satisfaction in patients undergoing reconstruction a bone-patellar tendon-bone (BPTB) autograft. Methods: We prospectively recruited BPTB autograft at single institution. Subjects were randomized pre-operatively either or experimental groups pre-established randomization blinded their treatment group. Patients group received standard-of-care consisting 15-ml Bupivacaine (0.25%). 20-ml (0.25%) injected into interspace between popliteal artery capsule knee addition Bupivicaine ACB. Post-operative level, control, collected 24hrs, 48hrs, 72hrs one week postoperatively. Satisfaction assessed 0-10 numeric scale 0 equal not satisfied 10 completely satisfied. Pain measured Visual Analog Scale (VAS) from no extreme pain. type quantity medications including 325-5 mg Percocet, Tylenol, other recorded each time point. Variables Shapiro-Wilks test normality T-test non-parametric tests continuous variables Chi-squared categorical variables. Results: A total 20 preliminarily analyzed all having least 1 follow-up. mean age cohort 28.75 ± 9.15 years, body mass index (BMI) 24.0 4.82 kg/m 2 55% (n=11) Male. two arms consisted 12 arm 8 arm. There statistically significant differences age, BMI, sex (p > 0.05). who had significantly higher 24hrs post-operatively compared those did (7.62 vs. 5.25, p=0.01). less number prescribed opioids tablets than (8.5 11.15, p=0.52), 24 hours (51.12 65.17, p=0.24) 48 (51.00 57.92, p=0.55). (Table 1) Conclusions: exhibited better care alone tissue. [Table: see text]
