Continuous Vs Single Shot Block After ACL

Screening evaluation will occur during the preoperative visit prior to surgery which generally occurs within 28 days prior to surgery. No separate screening is indicated in this study.

Patients will be asked to participate in the study if they are having ACL Reconstruction surgery with one of the orthopedic surgeons who is participating in the study. They will be informed and consented in the office or in the preoperative holding area prior to surgery.

Patients undergo ACL reconstruction at either Plainview, Franklin, Huntington, Long Island Jewish, or North Shore University Hospital.

Any medical condition that is present at the time that the participant is screened will be considered as baseline and not reported as an adverse event (AE). However, if the study participant's condition deteriorates at any time during the study, it will be recorded as an AE.

Changes in the severity of an AE will be documented to allow an assessment of the duration of the event at each level of severity to be performed. AEs characterized as intermittent require documentation of onset and duration of each episode.

The investigator who is making phone calls to the given participant will record all reportable events with start dates occurring any time after informed consent is obtained until 7 (for non-serious AEs) or 30 days (for SAEs) after the last day of study participation. At each study visit/phone call, the investigator will inquire about the occurrence of AE/SAEs since the last visit/phone call. Events will be followed for outcome information until resolution or stabilization.

Study procedures and evaluations

• All patients who are enrolled in this study will have been evaluated and determined to be a candidate for ACL reconstruction surgery. The indications for surgery, determination of need for surgery and physical examination determining this need are independent from the interventions and outcomes being assessed by this study.
• Efficacy Assessment plan- All patients will be called on postoperative days 1,2,3,4, 7 via and be assessed in person at the post-operative visit. They will be surveyed for primary and secondary outcomes by a study investigator. Primary outcome will be assessed using visual analog scale 0-10. Secondary outcomes; Opiate consumption will be assessed documented during the phone call, Sleep will be assessed by either yes or no answer if the patient had a disturbance in their sleep or had trouble getting to sleep based on pain of the surgical knee in the past 24 hours.
• Screening evaluation will occur during the preoperative visit prior to surgery which generally occurs within 28 days prior to surgery. No separate screening is indicated in this study.
• Procedure for administering study intervention and follow-up procedures. The participant will be seen in the preoperative holding suite prior to surgery to ensure that patient is still willing to undergo randomization for the study. The patient will then undergo randomization by a computer-based software and the anesthesiologist will be informed of the plan. The participant will undergo anesthesia at the discretion of the anesthesiologist per routine given the participant's clinical baseline. The participant will undergo ACL reconstruction based on the standard of care treatment. Following surgery but prior to leaving the operating room the anesthesiologist will place the adductor canal block and the catheter based on the participant's randomization under ultrasound guidance to ensure proper placement of the block. The participant will then undergo routine post-operative care in the recovery suite with routine recovery room vital checks. For participants who are randomized to the continuous pump group, the pump will be assembled and filled by pharmacy and attached to the previously placed catheter while the participant is in the recovery room. Once the participants are awake and alert in the recovery room, a study investigator will review the study specifics again, including the phone calls with written information on the questions that will be asked. They will also be given written instructions on how to use the continuous pumps and how to remove it. If the patient is uncomfortable removing it themselves, they can come to the office to have it removed. For participants who received a continuous pump the investigator will go over the function of the pump, troubleshooting, and how to remove the pump at home. All participants will be discharged home from the recovery room after they have met the routine discharge criteria following existing standard of care recovery room protocols.
• All data will be recorded in an encrypted database which is HIPPA and IRB compliant. All participant information will be labeled with a participant study identification number with no identifiable information documented.
