The goal of this interventional clinical trial is to assess opioid consumption 24-48 hrs post anesthesia block among patients undergoing total knee arthroplasty. The main question it aims to answer is:
1. Is there a difference in opioid consumption 24-48 hours post block administration among patients that receive an adductor canal catheter (ACC) versus adductor canal block (ACB)?
Participants will be:
The purpose of this study is to see if adding a continuous ACB catheter will extend analgesia beyond the 24-48 hour period. This interventional clinical trial will assess opioid consumption in patients undergoing total knee arthroplasty 24 to 48 hours after anesthesia block. Rebound pain is a well-known phenomenon in which patients experience severe pain immediately after the nerve block is removed. It is also known that by extending the duration of analgesia, you can reduce or prevent rebound pain. Motor sparing compartment blocks have transformed patients' ability to participate in rehabilitation earlier than ever before, even ambulating on POD 0. Thus, by extending analgesia and encouraging early ambulation, adductor canal catheters are likely to not only reduce opioid consumption but also allow for earlier discharge. The two "hot" themes in recent total knee replacement analgesia pathways are not only providing an effective Enhanced recovery after surgery (ERAD) protocol, but also combating the opioid epidemic through regional anesthesia and non-opioid multimodal pathways. This study will assist in determining which modality is superior (single shot blocks with additive versus catheter) and will introduce a novel method of following patients at home via a transitional pain service (telemedicine). This research will further investigate chronic pain 6 months after surgery.
Patients in the intervention group will have a catheter that continuously infuses numbing medication into their operative leg for 50 hours (up to POD 3). It is hypothesized that the patient will have better pain control, mobility, and less rebound pain, which is common following POD 1. By infusing the catheter with a disposable single use ambIT system (Summit Medical Products), all patients enrolled in the intervention group (ACC) will have the same amount running continuously, allowing the patient to be discharged with the catheter in place before the 50-hour infusion is completed. Prior to discharge, patients will be instructed on how to remove the catheter and will be able to download the Smartphone app "Diagnotes" at the hospital. While the catheter is in place, the Diagnotes app (a HIPPA-compliant text messaging service) will be the patient's primary means of communication with the pain doctor at home.
Patients in the control group will have a sham (fake) catheter attached to their operative leg for 50 hours. Patients will also be instructed on how to remove the catheter prior to discharge and will be able to download the Smartphone app "Diagnotes" in the hospital. While the catheter is in place, the Diagnotes app (a HIPPA-compliant text messaging service) will be the patient's primary means of communication with the pain doctor at home.
Researchers will contact both groups for follow-ups for up to 6 months.

Participants will be randomized to the intervention group (adductor canal catheter, ACC) or control group (sham adductor canal catheterm, ACB). The research staff and participants will be blinded as to which group the participant is in. The primary investigator and co-investigators will not be blinded. The research staff will provide PI and Co-I with an envelope that informs them which group the participant is randomized to so the proper research activities are carried out.
