NCT04749615

Brief Summary

The goal of this clinical trial is to determine whether Periarticular Injection (PAI) alongside Adductor Canal Block (ACB) and Infiltration between the Popliteal Artery and Capsule of the Knee (IPACK) block can decrease post-operative pain in patients undergoing primary total knee arthroplasty. The main question it aims to answer is:

  • Is ACB/IPACK without PAI as effective as ACB/IPACK with PAI for TKA patients? Participants will be assigned to one of the following groups at random:
  • ACB/PACK with PAI
  • ACB/IPACK with saline injection Participants will also be asked to complete pre- and post-operative questionnaires.

Outcome Measures

Primary Outcomes (1)

  • Pain Scores (NRS, 0-10) With Ambulation on POD1

    The NRS (numeric rating scale) is a questionnaire that measures pain on a numeric scale, 0 (no pain) to 10 (worst pain imaginable). The questionnaire will be asked on post operative discharge day 1.

    24 hours Post Operative Discharge

Secondary Outcomes (17)

  • Opioid Use (Cumulative Oral Morphine Equivalents POD0-POD2, 2 Weeks, 3 Months)

    post surgical discharge, 24 hours post surgical discharge, 48 hours post surgical discharge, 2 weeks post surgical discharge, and 3 months post surgical discharge.

  • NRS Pain With Movement

    pre-operation, in the post anesthesia care unit (PACU), at post operative (POD) 1, POD 2, and POD 3 months

  • Numerical Rating Scale (NRS) Pain Score at Rest

    from pre-operation, post anesthesia care unit (PACU), post operative day (POD) 1, POD 2, and POD 3 months

  • PAIN OUT Questionnaire at Preoperation

    at preoperation

  • Quality of Recovery (POD1)

    24 hours post surgical discharge.

  • +12 more secondary outcomes

Study Arms (2)

No PAI + ACB & IPACK

PLACEBO COMPARATOR

Control: saline injection (same injection technique and volumes as described for the active intervention, of normal saline)

Drug: Saline Control Periarticular Injection (PAI)

PAI + ACB & IPACK

ACTIVE COMPARATOR

Active intervention: Periarticular injection: one deep injection prior to cementation and then a second more superficial injection prior to closure. The deep injection will consist of bupivacaine 0.25% with 1:200,000 epinephrine, 30 cc; morphine, 8 mg/ml, 1cc; methylprednisolone, 40 mg/ml, 1 ml; cefazolin, 500 in 10 ml; normal saline, 22cc. The superficial injection will be 20 ml 0.25% bupivacaine

Drug: Periarticular Injection (PAI)

Interventions

PAI is a widely-utilized, surgeon-performed, analgesic intervention for TKA patients.

PAI + ACB & IPACK

equal volume of saline will be used in place of analgesics used in PAI injections

No PAI + ACB & IPACK
