About this study
The study purpose is to compare the effectiveness of different methods for post-operative pain treatment after total knee replacement.
Read the detailed description
Total knee replacement (TKR) is known to be one of the most painful surgical procedures. Many treatments have been used post TKR: IV opioids, epidural infusions, peripheral nerve blocks. No one method has been recognised as the best one.
In this study we will compare two well established methods of pain treatment:
- continuous infusion of local anesthetics + opioids into the epidural space,
- patient controlled analgesia with IV Morphine.
The study design is double blind.
Patients will have a combined spinal-epidural anesthesia for the operation and then will be connected to 2 different pumps, one to the epidural catheter and one to the intravenous catheter, for the first 24 hours post-operatively.
Pain scores, total analgesic medications other than study medications, adverse reactions to study medications, complications and patient satisfaction will be followed by blinded observers and compared between groups.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Marcaine 0.166% + Fentanyl 3.33 mcg/ml and Morphine sulphate in people with Pain, Postoperative and Osteoarthritis, run by Rambam Health Care Campus at 1 site in Israel.
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 6 inclusion and 12 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: stopped early, as of the sponsor's last update on 11 Apr 2007. 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 Israel. 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?
The study was stopped early (reason given: We believe regional anesth better for TKR,90% patients got epidural. Last year we started spinal morphine one shot, and found it very promissing.). Results are not available in the source record.
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?
Visual analog scale (VAS) (rest/movement) during first 24 hours post-operation. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00270322, which also lists 6 linked publications.
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 11 Apr 2007; AzTrials last refreshed its copy on 7 Nov 2026.
