There is diversity of utilizing these techniques.</p><p><strong>Objective:</strong> To evaluate the efficacy of postoperative pain control and walking ability between different anesthetic techniques used in TKA.</p><p><strong>Material and method:</strong> A retrospective analytical study was conducted among 153 patients receiving TKA during August 2018 – July 2019 under 5 different anesthetic techniques; group 1: SA+ACB 55 cases, group 2: SA+PAI 13 cases, group 3: SA+MO 63 cases, group 4: GA+PAI/ACB 9 cases and group 5: GA 13 cases. Postoperative pain score at 2, 24, 48 hours and ability to walk with walker within 48 hours were compared between groups.</p><p><strong>Result:</strong> The mean 2-hrs pain score in GA group was 4.5 (SD 2.2), significantly higher than group 1−4. The average 24-hrs pain score in GA group was 4.3 (SD 2.0), significantly higher than group 1, 3 and 4. At 48 hours, the mean pain<br />score in GA group (3.5, SD 1.3) was higher than SA+ACB (2.6, SD 0.9, p=0.035) and GA+PAI/ACB group (2.1, SD 0.6, p=0.012). The pain scores in group 1−4 were not significantly different, no matter when assessed at 2, 24 or 48 hours. Percentages of patients with satisfied walking ability in SA+ACB and SA+PAI groups were higher than those of GA+PAI/ACB and GA groups (92.7% and 92.3% vs 55.6% and 53.8% respectively, p=0.002)</p><p><strong>Conclusion:</strong> Using PAI or ACB, combined with either SA or GA provided similar effectiveness of postoperative pain control in TKA, and not different from SA+ MO. Combination of these techniques had better results than using GA alone.</p> ER -
