Abstract
Background: Effective post-operative pain control in
patients undergoing total knee arthroplasty is a key
point which make patients early ambulation, effective
rehabilitation, early recovery, decrease length of hospital
stay and decrease peri-operative complications. In this
study, we hypothesized that adductor canal block with
IPACK block technique was more effective than adductor
canal block alone for post-operative pain control in TKA
cases.
Methods: Patients undergoing TKA in 2019-2020 total 16
cases were randomized into 2 groups. The first group was
ACB and IPACK block for post-operative pain control, and
second group was ACB alone. Numerical rating scale,
amount of analgesic drug, complications, and satisfaction
scores was recorded for compare between two groups.
Results: ACB with IPACK block showed statistically
significant less accumulative morphine used at 12 hours
postoperative period than ACB alone (1.5 1.6 ± vs 3.75 ±
1.39; p = 0.015). We found no significant differences in
the two groups with regard to numerical rating scale,
amount of analgesic drug, complications, and satisfaction
scores. Conclusion: ACB with IPACK block technique provide
effective post-operative pain control for TKA patients. This
technique significantly less accumulative morphine used
at 12 hours postoperative than ACB alone.
