Pain Levels and Opioid Usage in Three Nerve Block Cohorts in Primary TKA

Not Applicable
Withdrawn
Conditions
Knee Arthropathy
Interventions
Other: preop ACB, followed by Intra-articular block during TKA surgery
Other: preop ACB+IPACK block
Other: preop ACB+IPACK block, followed by Intra-articular block during TKA surgery
Registration Number
NCT04292392
Lead Sponsor
University of Louisville
Brief Summary

The primary objective of this study is to compare effect of combined block of ACB (adductor canal block) with IPACK (Interspace between the Popliteal Artery and the Capsule of the posterior Knee) block and/or Intra-articular block in immediate postoperative and early postop rehabilitation and pain management in patients undergoing primary TKA. The secondary objective is to review both in-hospital and post-discharge pain levels and narcotic usage of primary TKAs, with a minimum 6-week postoperative follow-up.

Primary Outcome Measures
NameTimeMethod
Distance that patient is able to walkoutcome measure will be taken 24 hours postoperatively, 48 hours postoperatively, 72 hours postoperatively, 2 weeks (± 4 days) postoperatively, and 6 weeks (± 2 weeks) postoperatively

Distance that patient is able to walk, as measured in feet

Visual Analog Scaleoutcome measure will be taken 24 hours postoperatively, 48 hours postoperatively, 72 hours postoperatively, 2 weeks (± 4 days) postoperatively, and 6 weeks (± 2 weeks) postoperatively

The Visual Analog Scale measures the patient's level of knee pain on a scale of zero to ten via what the patient expresses verbally. The Visual Analog Scale (VAS) represents the degree of pain that the patient is experiencing at the time the measure is taken. Zero represents "pain-free". A 10 would represent pain so excruciating as to warrant emergency medical assistance, or as it is described to the patient, "the worst pain imaginable". Obviously, the lower the number, the better the outcome. There is no subscale.

WOMAC scoreoutcome measure will be taken preoperatively (4-6 weeks prior to date of surgery) and 6 weeks (± 2 weeks) postoperatively

WOMAC score as recorded preoperatively and 6 weeks (± 2 weeks) postoperatively. The score is on a scale from 0-100. In contrast to the Knee Society Score, on the WOMAC a lower value represents a better outcome.

Ability to rise from a chair independentlyoutcome measure will be taken 24 hours postoperatively, 48 hours postoperatively, 72 hours postoperatively, 2 weeks (± 4 days) postoperatively, and 6 weeks (± 2 weeks) postoperatively

Ability to rise from a chair independently (Yes/No)

total length of hospital stayoutcome measure will be taken at 2 weeks postoperatively

total length of hospital stay as defined by number of days from date of surgery to date of discharge

Knee Society Scoreoutcome measure will be taken preoperatively (4-6 weeks prior to date of surgery) and 6 weeks (± 2 weeks) postoperatively.]

Knee Society Score as recorded preoperatively and 6 weeks (± 2 weeks) postoperatively. The score is on a scale from 0-100. A higher value represents a better outcome

Amount of narcotic medication utilizedoutcome measure will be taken 24 hours postoperatively, 48 hours postoperatively, 72 hours postoperatively, 2 weeks (± 4 days) postoperatively, and 6 weeks (± 2 weeks) postoperatively

Amount of narcotic medication utilized (daily dosage measured as a Milligram Morphine Equivalent (MME) value).

Use of an ambulatory assistive deviceoutcome measure will be taken 24 hours postoperatively, 48 hours postoperatively, 72 hours postoperatively, 2 weeks (± 4 days) postoperatively, 6 weeks (± 2 weeks) postoperatively

Use of an ambulatory assistive device (Yes/No)

Active range-of-motion (ROM)outcome measure will be taken 24 hours postoperatively, 48 hours postoperatively, 72 hours postoperatively, 2 weeks (± 4 days) postoperatively, and 6 weeks (± 2 weeks) postoperatively

Active ROM (range-of-motion) as measured by a goniometer (range of 0-135 degrees)

Incidence of postop complicationsoutcome measure will be taken 6 weeks (± 2 weeks) postoperatively

Incidence of any postoperative complication that involves hospital readmission and/or a re-operation of the surgical knee.
