Clinical Trial Summary

Total knee arthroplasty (TKA) is a frequent performed surgery. Many institutions are implementing fast track programs for this surgery and adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. The purpose of this study is to evaluate effectiveness and safety of using CNB in patients undergoing ambulatory TKA, and its effects on patients' quality of recovery. Investigators hypothesize that continuous adductor canal block would lead to decrease in opioid consumption in patients undergoing fast track TKA. Significance There are no published prospective randomized controlled trials to assess patient's reported quality of recovery after receiving CACB in same day primary knee arthroplasties. As this is a frequent type of surgery and has the prediction to increase its incidence for the next years, there is significant importance in investigations about interventions which may improve its recovery in a fast track regime. A postoperative analgesic technique that offers better pain control, has less adverse effects, reduces the opioid analgesia requirement and is safe to be used in a fast track setting may have additional impact on decreasing health care cost and may lead to an enhanced recovery and better quality of life. Objectives To evaluate effectiveness and safety of using CACB in patients undergoing ambulatory TKA, in comparison to SACB. Primary objective is opioid consumption (in oral morphine equivalent doses) Secondary objectives are to evaluate postoperative QoR-15 scores (10), pain scores, opioid-induced adverse effects (measured via validated opioid symptom distress scale), postoperative functional status, complications relating to the perineural catheter and readmissions.

Description:

Objectives The aim of this study is to examine the effect of CACB on decreasing opioid consumption, increasing the Quality of Recovery (measured via QoR-15) total score and decreasing opioid-related side effects. Investigators will also assess the rate of readmissions in primary knee arthroplasty patients. Rationale Pain management in knee arthroplasty patients poses unique challenges for the anesthesiologist, especially in the immediate post-operative period. Early postoperative analgesia is limited to a unimodality of intravenous opioids. Recently, adductor canal blocks have started to replace femoral blocks, as this technique can provide similar analgesic results while avoiding the quadriceps muscle weakness associated with femoral nerve blocks. The use of a continuous adductor canal catheter in the post-discharge phase shows promising as the next step in knee arthroplasty pain management allowing for shorter lengths of stay or even same day discharge (3). Significance and Innovation Total knee arthroplasty (TKA) is the second most common inpatient surgery in the U.S. and Canada, and is associated with severe postoperative pain, limiting early ambulation and optimal functional recovery. Perioperative opioid use has been linked with many adverse outcomes including opioid dependence. This study aims to demonstrate the utility of CACB as an adjunct strategy to reduce opioid consumption and improve quality of recovery in primary knee arthroplasty patients. The innovation in this approach lies not only in less opioid consumption and opioid induced side effects but also in reducing the burden of postoperative pain, leading to an enhanced recovery and better quality of life. Establishing the safeness of this method in an outpatient setting may have the additional impact of decreasing health care costs and may lead to reduce opioid prescriptions on discharge from the hospital. This will be the first study assessing patient's reported quality of recovery after receiving CACB for primary knee arthroplasties. Investigators expect that that the use of CACB will improve patients' quality of recovery, alleviate pain and also reduce opioid consumption and side effects. Methodology This will be a prospective, randomized double blind placebo controlled clinical trial. There will be two arms of treatment: intervention and control group. Preoperatively patients will be allocated at random to receive either Continuous adductor canal block (CACB) (intervention group) or sham continuous adductor canal block (ShACB) (control group). Work Plan This prospective trial would include unilateral primary TKA done under Fastrack protocol. The subjects will have their surgeries booked in advance and they will be submitted to the pre anesthesia consult at the Pre-Admission Unit a few days before the surgery. The study proposal will be explained to the patients at time of preadmission consult. They will receive a booklet with information about the study and the Consent Form that they will bring home with them. Patients will be randomized to one of the two groups using a computer-generated random numbers table. The elastomeric pumps to be used connected to the catheter will be previously prepared by hospital pharmacy, accordingly to the randomization made and the subject study number, with no identification of the content (NaCl 0.9% or Ropivacaine 0.2%). All patients will receive the same perioperative management. The only difference will be the postoperative continuous perineural infusion: the CACB group will receive an infusion of 0.2% ropivacaine 5mL/h and ShACB group will receive an infusion of NaCl 0.9% 5mL/h. Patients will initially be brought to a dedicated block room where a safety checklist will be performed by the block room team before performing the block. Standard Canadian Anesthesia Society monitoring will be provided. After surgery, the patient will be taken to the Post Anesthesia Care Unit. At this moment, an Arrow® (StimuCath® Continuous Peripheral Nerve Block Catheter) continuous adductor canal block catheter will be inserted using a Sonosite Edge II ultrasound machine. The patient may be discharged home after achieving the discharge criteria, keeping the peripheral nerve catheter with the same infusion rate for the planned time. The adductor canal catheter will infuse for 48 hours. Prior to going home, patients will receive education and written information (educational pamphlet) regarding monitoring for local anesthetic systemic toxicity symptoms, possible CABC associated complications including potential transient muscle weakness, and instructions on patient removal of the catheter after 48 hours. The study coordinator will collect the data once a day at 24, 48, 72 hrs, seven, 30 and 90 days postoperatively. Data collection will require at maximum 15 minutes. Sample Size Sample size justification was based on the primary outcome, and the primary objective. The sample size was calculated based on previous study (12) that showed a 48-hour opioid consumption of 30mg (+/- 15 mg) morphine equivalents in knee replacement surgeries at our institute. Investigators anticipate a 50% decrease of opioid use in the intervention group with an alpha of 0.05, power of 80%, and an enrolment ratio of 1:1 (between the 2 groups). This will require 16 subjects in each group for a total of 32 patients. To compensate for 15 to 20% anticipated dropouts from the study, investigators plan for an inclusion of 40 patients.
