Abstract
This systematic review examines the efficacy of medical cannabis in pain management within orthopaedic domains, including arthritis pain, postsurgical pain, back pain, and post-trauma pain. Given the challenges and risks associated with traditional pain medications, particularly opioids, this review aims to assess the efficacy and safety of medical cannabis for orthopaedic pain management.
A literature search was conducted on databases such as PubMed and Cochrane to find primary research papers on the efficacy and safety of cannabis. A comprehensive analysis was conducted on available literature, focusing on studies that evaluated the efficacy and safety profile of medical cannabis in various orthopaedic pain conditions. Only randomised controlled trials (RCTs) were included to keep the evidence of high quality. The quality of the studies was assessed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool, and the risk of bias was assessed using the Cochrane Risk of Bias tool. The review particularly assessed the effectiveness of medical cannabis compared to no treatment, placebo, and active comparators. Additionally, the review examined the optimal dosing, methods of administration, and the safety profile of medical cannabis.
The review reveals minimal high-quality evidence supporting the efficacy of medical cannabis in the targeted orthopaedic areas. Most evidence suggests effectiveness only when compared with no treatment or placebo, with limited data against active comparators. The review also highlights the need for more research to determine optimal dosing and administration methods. The safety profile of medical cannabis, characterised by generally mild to moderate adverse effects, suggests its potential as a safer alternative or adjunct to opioid pain management.
The findings indicate that while medical cannabis may hold promise as an alternative or adjunct therapy in orthopaedic pain management, there is a need for more robust and methodologically sound research. Future studies should focus on long-term efficacy and safety, standardisation of dosing and administration, and comprehensive reporting of adverse effects. This is essential for developing effective treatment protocols that balance pain relief with safety and understanding the role of medical cannabis in orthopaedic pain management.
