Comparison of Regional Analgesia techniques in TKA

Comparision A vs B	Rest VAS at 24 h	Rest VAS At 48h	Total OMEQC	ROM
ACB vs PAI	A≃B	A≃B	A>>>B*	A≃B
ACB + PAI vs PAI	A>>B*	A≃B	A>>>B*	A>>>B*
ACB + PAI vs ACB	A>>B*	A≃B	A≃B	A≃B
cACB vs ACB	A>>B*	A>>>B*	A>>>B*	A>>>B*
LB vs PAI	A≃B	A≃B	A≃B	A≃B

Comparasion of weighted mean difference (WMD) (accumulative differences of studies weighted by the sample size) of studies with the same clinical outcomes and interventions. Two posoperative analgesic strategies (A vs B) after TKA were compared. Evaluating visual analoge scale (VAS) at rest, 24h and 48h posoperatively, total oral morphine equivalents consumption (OMEQC) and Range of Motion (ROM) are explained as no difference (A≃ B), small superoirity (A>B), moderate superiority (A>>B), large superiority (A>>>B) by the magnitude of the WND ( 0, 0-0.2, 0.2-0.8, >0.8 respectivily). ACB, adductor canal block; cACB, continuous adductor canal block; PAI, periarticular infiltration; LB, Liposomal Bupivacaine.
