Statins and Hip Pain: A Comprehensive Review
Introduction to Statins and Hip Pain
Statins, widely prescribed for lowering cholesterol, have been investigated for their potential effects on various conditions, including hip pain and osteoarthritis. This article synthesizes findings from multiple studies to understand the relationship between statin use and hip pain, particularly in the context of hip surgery, osteoarthritis, and fracture risk.
Statins and Postoperative Hip Pain
Perioperative Statin Use and Postoperative Pain
A study examining the effects of perioperative statin use on postoperative pain and opioid consumption after hip replacement surgery found no significant difference between statin users and non-users. The pain scores and opioid requirements during the initial 72 hours post-surgery were equivalent in both groups, suggesting that routine statin use does not alleviate postoperative pain in hip surgery patients1.
Statins and Hip Osteoarthritis
Statins and Osteoarthritis Progression
Research on the impact of statins on osteoarthritis (OA) progression has yielded mixed results. A study from the Rotterdam cohort indicated that while statin use was associated with a significant reduction in the progression of knee osteoarthritis, it did not show a similar effect on hip osteoarthritis2. Another study focusing on elderly women found that statin use might increase the risk of developing new radiographic hip osteoarthritis but did not significantly affect the progression of existing hip OA3.
Statins and Clinical Outcomes in Hip and Knee OA
A pooled analysis of four cohort studies involving over 132,000 individuals found no overall reduction in the risk of developing clinically-defined hip or knee osteoarthritis with statin use. This large-scale study concluded that statins do not confer a protective effect against the development of OA requiring medical consultation or surgery4.
Statins and Hip Fracture Risk
Statins and Fracture Prevention
Several studies have explored the relationship between statin use and hip fracture risk. A retrospective cohort study in a Medicaid population suggested that statin users had a lower risk of hip fractures compared to non-users, although this protective effect might be influenced by unmeasured confounding factors5. Similarly, a Finnish cohort study found that long-term statin use was associated with a reduced risk of low-energy hip fractures in middle-aged and elderly women6. In men, statin use was also linked to a lower risk of hip fractures, with the strongest protective effect observed in older age groups and African Americans7.
Meta-Analysis on Statins and Bone Health
A comprehensive meta-analysis of 33 clinical trials concluded that statin treatment is associated with a decreased risk of overall fractures, including hip fractures. The analysis also found that statins improved bone mineral density at the total hip and lumbar spine, suggesting a beneficial effect on bone health9. Another Danish case-control study supported these findings, showing a reduced risk of hip fractures among statin users, particularly those with higher prescription counts10.
Conclusion
The relationship between statins and hip pain is multifaceted. While statins do not appear to reduce postoperative pain following hip surgery, they may have a protective effect against hip fractures and potentially influence the progression of osteoarthritis. However, the evidence is mixed, and further research is needed to clarify these associations and determine the underlying mechanisms. Overall, the benefits of statins in cardiovascular disease prevention remain well-established, and their potential effects on hip pain and bone health warrant continued investigation.

Are perioperative therapeutic doses of statins associated with postoperative pain and opioid consumption after hip surgery under spinal anaesthesia?
Statin use during hip surgery does not significantly impact postoperative pain or opioid consumption, suggesting no need for routine statin use as part of an analgesic regimen.
