Association between #statin use and incidence or progression of #osteoarthritis: Meta-analysis of observational studies

..A total of 11 studies (679807 participants) were identified from the systematic literature search. No significant association between statin use and incidence (OR = 1.010; 95% CI: 0.968 to 1.055; P = 0.638) or progression (OR = 1.076; 95% CI: 0.824 to 1.405; P = 0.589) of OA was found in our meta-analysis. The meta-analysis according to the symptomatic or radiological OA also found no significant association between statin use and OA. The subgroup analysis showed that atorvastatin (OR = 0.953; 95% CI: 0.911 to 0.998; P = 0.041) and rosuvastatin (OR = 1.180; 95% CI: 1.122 to 1.241; P < 0.0001) had opposite effects on OA. The results of the analysis according to the joint site, interval, and statin dose were all not significant.

Conclusions
Statin use may not be associated with a lower risk of incidence and progression of OA, regardless of joint site. The opposite effects of atorvastatin and rosuvastatin were detected in OA.
