Psychiatric, Cardiovascular and Skeletal Risks of Codeine versus Oxycodone in Hip Osteoarthritis: A Population-Based Cohort Study

Codeine use in patients with hip osteoarthritis was associated with a higher risk of psychiatric disorders and distinct fracture patterns. The observed risks varied according to patient characteristics, comorbidities, and concomitant medications, emphasizing the need for individualized opioid prescribing strategies that incorporate psychiatric monitoring, fracture risk assessment, and patient-specific factors. Further controlled studies integrating clinical, lifestyle, and genetic data are warranted to confirm these findings and refine personalized opioid therapy in hip osteoarthritis.
