Study summary

The primary purpose of this study is to evaluate postoperative pain. Secondary outcomes evaluated in this study will include range of motion (ROM), opioid consumption, and ambulation. Each outcome measure will be evaluated, oral tranexamic acid (TXA) in the experiment arm and placebo in the control arm, after total knee arthroplasty (TKA) at postoperative days 0-3, and weeks 1, 2, 6, and 12.

Read the detailed description

Randomized controlled trial with 1:1 allocation, selected through computer-based randomization.

This study will review prospectively collected data, including patient demographic information, surgeon, use of oral tranexamic acid (TXA) or placebo regimen, and postoperative outcomes up to 3 months after surgery. Collaboration with Saint Francis' pharmacy team will be performed to ensure appropriate blinded administering of the oral TXA and placebo medication.

This will be a double blinded study, with both patient and surgeon blinded to study group.

6.0 TXA dosing protocol TXA day of surgery [All patients]

  • Administer 1-gram IV TXA intraoperatively at the start of the case (hold for history of stent within 1 year of surgery)

    o AND

  • Administer 1-gram IV TXA postoperatively before leaving PACU (hold for history of stent within 1 year of surgery)

    o OR

  • Exception: Administer 2 grams TXA in 50cc normal saline topically during the case for patients with a history of stent placed within one year of surgery.

TXA postoperative day (POD) 1-3 [Experimental group]

  • Administer 1.95 grams oral (3- 650 mg tablets) TXA each morning for three days following surgery.
  • Patients discharged home before POD 3 will be sent home with remaining oral TXA doses.

Placebo POD 1-3 [Control group]

  • Administer oral placebo (3 tablets) each morning for three days following surgery.
  • Patients discharged home before POD 3 will be sent home with remaining oral placebo doses.

Eligibility criteria

Inclusion Criteria:

    • All patients undergoing either manual or robotic primary total knee arthroplasty (TKA)
  • Performed by participating Connecticut Joint Replacement Institute (CJRI) surgeons (Dr. Matthew Grosso, Dr. Robert McAllister, Dr. Chad Daniel, Dr. Eric Silverstein, Dr. Alex Dukas, Dr. Michael Joyce, Dr. Brett Wasserlauf).

  • Exclusion for IV oral tranexamic acid (TXA):

    • TXA allergy - there are NO absolute contraindications for TXA use.
    • History of stent placed within one year of surgery - patient will receive topical TXA as an alternative.
  • Exclusion for oral TXA:

    o Actively treated cancer or deep vein thrombosis (DVT)

  • Chronic opioid use (opioid use within the 4 weeks prior to surgery)
  • Allergies to nonsteroidal Anti-inflammatory drugs (NSAIDs) and acetaminophen

What researchers measure

Primary outcomes

  1. Visual Analogue Scale (VAS) Pain scores

    Patient reported pain score from 0 to 10 where 0 is no pain and 10 is the most pain. Higher scores are a worse outcome.

    Time frame: postoperative day (POD) 0, 1, 2, 3 (+/- 0 days) and weeks 1 (+/- 0 days), 2 (+/- 2 days), 6 and 12 (+/- 7 days).

Secondary outcomes

  1. Range of Motion

    Clinical measurement of passive, pain-free range of motion of knee in degrees from 0 to 180 from maximum extension to maximum flexion

    Time frame: at 2, 6 and 12 week follow up visits

  2. Opioid consumption

    Subjects will keep a log recording opioid consumption. Research staff will ask subjects to report opioids during postoperative telephone calls.

    Time frame: POD 1, 2, 3 (+/- 0 days) and weeks 1 (+/- 0 days), 2 (+/- 2 days), 6 and 12 (+/- 7 days)

  3. Ambulation Status

    Surgeon or physical therapist will record if patient is using a walker, cane or no assistive devices.

    Time frame: at 2, 6 and 12 week follow up visits
