Trial summary

There are 2 common ways to manage pain after total knee arthroplasty at our institution. Some patients receive an epidural analgesia, a femoral nerve block and pills for pain. More recently, some surgeons have replaced femoral nerve blockade with peri-articular injections. Read more about this study

About this study

There are 2 common ways to manage pain after total knee arthroplasty at our institution. Some patients receive an epidural analgesia, a femoral nerve block and pills for pain. More recently, some surgeons have replaced femoral nerve blockade with peri-articular injections. These patients receive a peri-articular injection (injection of pain medication around the knee), pills for pain and a pain patch on the skin. The purpose of this research project is to find out if one of these ways to treat pain is better than the other. The investigators will look at this question in many ways, but the main way is how long it takes for you to be judged ready for discharge from the hospital.

Being tested
Peri-Articular Injection, Epidural Pathway (PCEA+FNB)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Peri-Articular InjectionProcedure or surgery

    Pre-operative anesthesia/analgesia: meloxicam (7.5 or 15mg), dexamethasone (6mg) Anesthetic:: Combined Spinal-Epidural with 0.5% bupivacaine. IV sedation with midazolam, propofol Antiemetic: 20mg famotidine, 4mg ondansetron Postoperative pain management: hydromorphone/bupivacaine PCEA (4/4/10/20, initially). Meloxicam (7.5 or 15mg), Oxycodone/Acetaminophen (5/325 3hr PRN)

  • Epidural Pathway (PCEA+FNB)Procedure or surgery

    Pre-operative anesthesia/analgesia: meloxicam (7.5 or 15mg), extended release oxycodone (10mg or 20mg), dexamethasone (6mg), clonidine patch (100 mcg/24 hr) Anesthetic: Spinal with 0.5% bupivacaine, IV sedation with midazolam, propofol Antiemetic: 20mg famotidine, 4mg ondansetron Post-operative analgesia:Prilosec (20mg), Meloxicam (7.5mg or 15 mg PO), extended release oxycodone (10mg or 20mg), Oxycodone (5mg q 3 hr PRN), Acetaminophen (1000mg), ketorolac 15mg IV

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Primary Outcome is Time Until a Patient is "Ready for Discharge."

    The primary outcome is time until a patient is "ready for discharge." Discharge criteria are:

    • PCA (if present) has been discontinued
    • Not experiencing moderate or severe nausea (within last 4 hours).
    • Solid food diet
    • Able to urinate (Foley catheter removed)
    • Pain: NRS <4.
    • Surgical wound dry
    • No acute medical problems
    • Physical Therapy Criteria
    • Independently transfer from supine to sit, from sitting to standing
    • Ambulate 40 ft. without assistance
    • Extension range of motion (< 10 degrees)

    Measured: Participants will be followed for the duration of their hospital stay, an expected average of 3 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Peri-Articular Injection and Epidural Pathway (PCEA+FNB) in people with Readiness to Discharge, run by Hospital for Special Surgery, New York at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Apr 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Primary Outcome is Time Until a Patient is "Ready for Discharge." (time frame: Participants will be followed for the duration of their hospital stay, an expected average of 3 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Apr 2022.
