CAA Use Tied to Higher Arthroplasty Risk

In a UK cohort, patients with osteoarthritis who initiated centrally acting analgesics had a higher hazard of knee or hip replacement than those who initiated SSRIs, though residual confounding by pain severity remains a key limitation.

Objective:

To evaluate the association between the initiation of centrally acting analgesics (CAAs) and the risk of knee or hip replacement in patients with osteoarthritis compared to those initiating selective serotonin reuptake inhibitors (SSRIs).

Key Findings:
  • In patients with both osteoarthritis and depression, the association was smaller, showing a 59% higher hazard of knee or hip replacement with CAA initiation.
Interpretation:

Limitations:
  • Potential residual confounding by indication remains, as patients prescribed CAAs may have had more severe pain or functional limitations.
  • The database did not capture pain severity, functional limitation, or radiographic osteoarthritis severity.
Conclusion:
