Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 40-75 with knee osteoarthritis experiencing significant pain for at least three months.

Probably not a fit

Patients with recent knee injections, cognitive impairments, or a history of cannabis abuse may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of orally dissolving cannabidiol (CBD) tablets in reducing pain and improving function in patients with knee osteoarthritis. It is a multi-center, double-blinded, randomized, placebo-controlled trial comparing outcomes between patients receiving CBD and those receiving a placebo while undergoing physiotherapy and home exercises. Participants will rate their pain and satisfaction at multiple time points throughout the treatment period to assess the impact of CBD on their condition.

Why it matters

Potential benefit: If successful, this study could provide a non-psychoactive treatment option for pain relief in knee osteoarthritis patients.

How similar studies have gone: Other studies have shown promise in using CBD for pain management, but this specific approach is still being evaluated.
