Tendinopathy and Tendon Rupture Associated with Statins

Area of Science:

• Pharmacology
• Orthopedics
• Rheumatology

Background:

• Statins are widely prescribed cholesterol-lowering drugs.
• Tendon disorders, including tendinopathy and rupture, can lead to significant morbidity.
• Co-existing medical conditions and concomitant medications may influence drug-induced adverse events.

Purpose of the Study:

• To review the association between statin use and tendinopathies/tendon ruptures.
• To identify risk factors and patient populations potentially at higher risk.
• To inform clinical practice regarding patient counseling and management.

Main Methods:

• Literature review of studies investigating statin-associated tendon injuries.
• Analysis of reported cases linking statins to tendinopathy and tendon rupture.
• Examination of patient comorbidities and concurrent medication use in reported cases.

Main Results:

• Statin use is associated with tendinopathies and tendon ruptures, notably affecting the Achilles, quadriceps, and distal biceps tendons.
• Onset of tendinopathy typically occurs within the first year of statin therapy and is reversible upon drug cessation.
• Increased risk of tendon rupture is observed in patients with diabetes, gout, rheumatoid arthritis, and chronic kidney disease.

Conclusions:

• Patients on statins, especially those with pre-existing systemic conditions or on concurrent medications like corticosteroids or fluoroquinolones, face an elevated risk of tendon injury.
• Education on this risk and exploration of alternative treatments, including lifestyle modifications, are crucial for at-risk patients.
