Abstract

ABSTRACT Introduction This study aimed to evaluate the relationship between a history of bicycling and symptomatic and structural outcomes of knee osteoarthritis (OA), the most common form of arthritis. Methods This was a retrospective, cross-sectional study within the Osteoarthritis Initiative (OAI), where we investigated OAI participants with complete data on bicycling, knee pain, and radiographic evidence of knee OA. We used a self-administered questionnaire at the 96-month OAI visit to identify participation in bicycling during four time periods throughout a participant’s lifetime (ages 12–18, 19–34, 35–49, and >50 yr). Using logistic regression, we evaluated the influence of prior bicycling status (any history, history for each time period, number of periods cycling) on three outcomes at the 48-month OAI visit: frequent knee pain, radiographic OA (ROA), and symptomatic radiographic OA (SOA), adjusting for age and gender. Results A total of 2607 participants were included: 44.2% were male, mean age was 64.3 (SD, 9.0) yr, and body mass index was 28.5 (SD, 4.9) kg·m−2. The adjusted risk ratios for the outcome of frequent knee pain, ROA, and SOA among those who reported any history of bicycling compared with non-bicyclers were 0.83 (0.73–0.92), 0.91 (0.85–0.98), and 0.79 (0.68–0.90), respectively. We observed a dose–response among those who participated in bicycling during more time periods. Conclusions People who participated in bicycling had a lower prevalence of frequent knee pain, ROA, and SOA. The benefit appeared cumulative. This study indicates that bicycling may be favorable to knee health and should be encouraged.
