Opioid Reduction in Orthopaedic Surgery (OREOS) - Knees
A study testing Multicomponent opioid reduction and pain management pathway in people with Knee Osteoarthritis and Chronic Post Operative Pain, run by Kim Madden at 1 site in Canada.
Trial summary
Knee replacements are the second most common surgery in Canada. Most patients recover very well but research consistently shows that 1 in 5 patients still have pain many months after surgery. Doctors often prescribe opioid medications for pain after surgery (e.g. Percocet, hydromorphone, codeine). Read more about this study

About this study
Official title: Opioid Reduction in Orthopaedic Surgery (OREOS): a Feasibility Randomized Controlled Trial in Knee Replacement Patients
Knee replacements are the second most common surgery in Canada. Most patients recover very well but research consistently shows that 1 in 5 patients still have pain many months after surgery. Doctors often prescribe opioid medications for pain after surgery (e.g. Percocet, hydromorphone, codeine). These medications can be helpful for some people, but they can also be dangerous, particularly when used for a long time. Many patients don't like the way opioids make them feel and would prefer alternative pain management strategies. Some people become addicted to opioids, have a difficult time reducing the dose of opioids, or have lasting health problems after using them.
People in this study will be randomized to either have usual care or a new pathway designed to improve pain control and decrease opioid use after knee replacements. This study will have an intervention coordinator who will assess patients before surgery and who will follow up with patients regularly after surgery to make sure their pain is controlled and to avoid long-term opioid use. This study will use education, physiotherapy, psychological therapy, ice/cold, and non-opioid pain medications. As pain medications may work differently in different patients, the coordinator will check on each patient to look for pain control and assist to reduce the amount of opioids used after surgery.
This study will help people have safer and more effective pain management after surgery which may lead to better recovery, higher satisfaction, and a lower risk of being harmed by opioids after surgery.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Knee replacements are the second most common surgery in Canada. Most patients recover very well but research consistently shows that 1 in 5 patients still have pain many months after surgery. Doctors often prescribe opioid medications for pain after surgery (e.g. Percocet, hydromorphone, codeine). These medications can be helpful for some people, but they can also be dangerous, particularly when used for a long time. Many patients don't like the way opioids make them feel and would prefer alternative pain management strategies. Some people become addicted to opioids, have a difficult time reducing the dose of opioids, or have lasting health problems after using them.
People in this study will be randomized to either have usual care or a new pathway designed to improve pain control and decrease opioid use after knee replacements. This study will have an intervention coordinator who will assess patients before surgery and who will follow up with patients regularly after surgery to make sure their pain is controlled and to avoid long-term opioid use. This study will use education, physiotherapy, psychological therapy, ice/cold, and non-opioid pain medications. As pain medications may work differently in different patients, the coordinator will check on each patient to look for pain control and assist to reduce the amount of opioids used after surgery.

Questions about this trial
What is this clinical trial studying?
A study testing Multicomponent opioid reduction and pain management pathway in people with Knee Osteoarthritis and Chronic Post Operative Pain, run by Kim Madden at 1 site in Canada.
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 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 3 Dec 2024. 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 Canada. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Intervention adherence [feasibility] (time frame: 8 weeks). The study lists 3 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 NCT04968132, which also lists 1 linked publication.
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 3 Dec 2024.
