Key takeaways:
- Use of beta-blockers was associated with a reduced likelihood of patients undergoing TKA for OA.
- Use of nonselective beta-blockers for more than 5 years was associated with the lowest likelihood of TKA.
Results showed use of beta-blockers was associated with a reduced chance of patients undergoing total knee arthroplasty, which could be due to a possible relationship between the autonomic nervous system and progression of osteoarthritis.
Researchers from the Hospital Regional Universitario de Málaga in Spain performed a nested case-control study of 300 patients with new-onset knee pain who underwent TKA and a matched cohort of 300 patients with new-onset knee pain who did not undergo TKA. They used binary logistic regression analysis to assess the likelihood of undergoing TKA among patients who used beta-blockers for the treatment of varying cardiovascular conditions vs. patients who did not use beta-blockers.
Overall, researchers found patients who had previously used any beta-blocker had a reduced likelihood of undergoing TKA (adjusted OR = 0.51) compared with patients who never used beta-blockers. Patients who had used selective beta 1-blockers and nonselective beta 1-blockers had adjusted ORs of undergoing TKA of 0.69 and 0.42, respectively. Adjusted ORs were 0.41 for patients who used beta-blockers for less than 1 year, 0.52 for patients who used beta-blockers for 1 to 5 years and 0.36 for patients who used beta-blockers for more than 5 years.
“This study provides insight to a possible relationship between the activity of the autonomic nervous system and the progression of OA,” the researchers wrote in the study. “In addition, it provides a hypothesis for the development of future therapeutic lines targeting the adrenergic system in the treatment of OA,” they concluded.
