INTRODUCTION

• Total knee arthroplasty is the most common orthopedic surgery in the lower

extremity performed in North America.

• The recovery after bilateral total knee arthroplasty (BTKA) is challenging, given

the need for effective pain control, early mobilization, and safe discharge home

• The aim is assess the effectiveness and safety of bilateral continuous adductor

canal block (B-CACB) and compare it to the bilateral single adductor block (BSACB)

technique in BTKA.

METHODS

• Retrospective study including patients scheduled for BTKA from 2020-2023

• Outcomes: Pain score, opioids consume (OME=oral morphine equivalent),

complications and mobilization assessment from a multidisciplinary team

including physiotherapist were registered.

RESULTS

• At 24-48 hours, the B-CACB group consumed an average of 20 mg/day less

(p=0.04, 95% confidence interval: 1.2 - 38.9 mg) of OME than B-SACB group .

• The B-CACB group was 3.5 times more likely to mobilize above 2 meters than BSACB

group in POD1 (OR: 95% confidence interval=1.2 – 9.9) and 4.5 times in

POD2 (OR: 95% confidence interval =1.2 – 16.3) as documented in the

physiotherapy assessment.

DISCUSSION

• B-CACB is a feasible , effective and safe plan for BTKA surgery in selected

population helping to successfully decrease the burden of two surgeries in one

surgical event.
