Overview
Brief Summary
This is a prospective, randomized, blinded study with a parallel design and an allocation ratio of 1:1 for the treatment groups. The investigators seek to determine if femoral nerve block (FNB) improves the quality of recovery and improve postoperative analgesia compared with adductor canal block (ACBs) for patients undergoing revision total knee arthroplasty.
Detailed Description
This is a prospective, randomized, blinded study with a parallel design and an allocation ratio of 1:1 for the treatment groups. A prospective study design will allow both FNBs and ACBs to be accurately assessed in an effective manner without introducing unnecessary confounding factors. Furthermore, randomization and a parallel design with equal allocation ratio will ensure timely enrollment of patients while also minimizing temporal confounders that may occur with institutional changes to clinical care protocols. Patients, nurses on the floor and physical therapists will be blinded to the nature of the patient assignment (FNB or ACB)

Outcomes
Primary Outcomes
Quality of recovery-15 item questionnaire (QoR): QoR-15
Time Frame: 48 hours after surgery
Our primary objective will be to determine if FNBs will result in improved quality of recovery (QoR-15) compared with ACBs (at 48 hours). The questionnaire is 15 questions with a scale from 0-10 on each and composed of two parts; part A and Part B scoring for questions in part A ( questions from 1-10) are scored from 0-10 where 0=none of the time( poor), and 10= all of the time (excellent). Part Bare questions from 11-15 where they are scored from (10-0) where 10=none of the time ( excellent) and 0=all of the time ( poor). The sum of all answers are added together
Secondary Outcomes
- Opioid consumption(48 hours post-op)
- Pain score measurement: we will use Numeric rating scale for measurement (NRS)(48 hours post-op)
