Whether or not running leads to the development of knee and hip osteoarthritis has been a much-debated topic and is often a question patients pose to their physicians. Recent literature adds to a growing body of evidence suggesting that lower-dose running may be protective against the development of osteoarthritis, whereas higher-dose running may increase one's risk of developing lower-extremity osteoarthritis. However, running dose remains challenging to define, leading to difficulty in providing firm recommendations to patients regarding the degree of running which may be safe. Furthermore, when counseling patients regarding their risk of developing lower-extremity osteoarthritis secondary to running, clinicians must consider many additional factors, such as the numerous health benefits from running and individual risk factors for developing osteoarthritis.
Lower-dose running may protect against osteoarthritis, whereas higher-dose running may lead to the development of osteoarthritis.
