Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug CBD Oil for postoperative knee pain?

The research does not provide direct evidence supporting the effectiveness of CBD Oil for postoperative knee pain. Studies have shown no significant difference in pain relief between CBD users and non-users in similar conditions, and further research is needed to determine its safety and effectiveness. ^{1 2 3 4 5}

How does CBD oil differ from other treatments for postoperative knee pain?

CBD oil is unique because it is a non-psychoactive compound derived from cannabis that may offer pain relief without the intoxicating effects associated with medical marijuana. Unlike traditional pain medications, such as opioids, CBD oil is being explored for its potential to manage pain with fewer side effects and a lower risk of addiction. ^{1 2 6 7 8}

What is the purpose of this trial?

This is a prospective, randomized, nonblinded trial to evaluate the effectiveness of Cannabidiol (CBD) oil on post-operative pain control compared to opioid medications after a knee arthroscopy.

Eligibility Criteria

This trial is for adults over 18 who need a knee arthroscopy due to soft tissue injury or other acute or chronic knee issues. Participants must be able to fill out surveys and come back for follow-ups. It's not for those under 18, with past major knee injuries, surgeries, other limb problems, or if pregnant.

Inclusion Criteria

Able to complete surveys and follow-up visits

I need a knee surgery for a tissue injury.

Exclusion Criteria

I have had a knee injury, surgery, or other leg issues before.

I am under 18 years old.

Pregnancy

Treatment Details

Interventions

• Cannabidiol Oil

Trial Overview The study is testing the effectiveness of CBD oil in managing pain after knee surgery compared to traditional opioid medications. Patients are randomly assigned to receive either CBD oil or opioids and their pain levels are monitored.

Participant Groups

Group I: Cannabidiol Oil 200 mg/day Experimental Treatment 1 Intervention

CBD 200mg PO liquid suspension QD starting 30 days prior to surgery and finishing 30 days post-operatively.

Group II: Cannabidiol Oil 100 mg/day Experimental Treatment 1 Intervention

CDB 100mg PO liquid suspension QD starting 30 days prior to surgery and finishing 30 days post-operatively

Group III: Standard of Care Active Control 1 Intervention

Opioid standard of care: Percocet (oxycodone 5mg-acetaminophen 325 mg) every 4 hours PRN postoperatively for 7 days

Findings from Research

In a study of 109 patients who underwent total hip or knee replacement surgeries, 22% reported using cannabidiol (CBD) during their treatment period.

Despite the prevalence of CBD use, there was no significant difference in pain satisfaction between those who used CBD and those who did not, indicating a need for further research on the safety and efficacy of CBD in this context.

Rates of self-directed perioperative cannabidiol use in patients undergoing total hip or knee arthroplasty. Yu, JS., Premkumar, A., Liu, S., et al.[2021]

In a study of 195 patients undergoing total hip and knee arthroplasty, 16.4% reported using CBD/THC products during the perioperative period, with higher usage in knee arthroplasty patients (22.6%) compared to hip arthroplasty patients (11.7%).

Despite the use of CBD/THC products, there was no significant difference in opioid consumption, pain scores, or length of hospital stay between users and non-users, suggesting that these products may not significantly impact post-operative opioid requirements.

In a study involving 20 healthy volunteers, an 800-mg oral dose of cannabidiol (CBD) did not significantly reduce pain intensity or affect hyperalgesia and allodynia compared to a placebo, suggesting limited efficacy in acute pain management.

The study highlights the need for further research on different dosages and administration methods for CBD, as well as its potential role in combination with other treatments, before concluding its effectiveness for acute pain.

In a randomized, double-blind, placebo-controlled trial involving 136 patients with hand osteoarthritis or psoriatic arthritis, cannabidiol (CBD) did not show a significant reduction in pain intensity compared to placebo after 12 weeks of treatment.

The study found no meaningful effects of CBD on secondary outcomes such as sleep quality, anxiety, or depression, indicating that CBD may not be an effective add-on therapy for pain management in these conditions.
