title: Patients who underwent total hip or knee arthroplasty are more physically active than the general Dutch population.
abstract: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) bring relief of pain and functional disability to patients with end-stage osteoarthritis, and however, the literature on their impact on patients' level of physical activity (PA) is scarce. Cross-sectional study in patients who underwent THA/TKA surgery in the preceding 6-22 months and a random sample of persons aged >40 years from the Dutch general population, participating in a national survey. PA in minutes per week (min/week) and adherence to the Dutch recommendation for PA (NNGB yes/no) were measured by the short questionnaire to assess health-enhancing PA. Multivariable linear (total min/week) and logistic regression analyses (meeting recommendations PA), adjusting for confounders, were performed for THA and TKA separately. In total, 258 THA [62.3% female, aged 69.4 (9.1)] and 221 TKA [65.7% female, aged 69.5 (8.9)] patients and 4373 persons from the Dutch general population [51.4% female, aged 58.9 (11.6)] were included. The presence of THA was associated after adjusting for age, sex, BMI education and musculoskeletal comorbidities, with more total min/week spent on PA (THA 13.8% increase, 95% CI 1.6-27.6%), whilst both TJA groups were associated with adhering to NNGB (THA: OR 1.79, 95% CI 1.26-2.56; TKA: OR 1.73, 95% CI 1.20-2.51). As this study used questionnaires to compare the PA of THA/TKA patients to the general population, some recall and selection bias might have been induced. After surgery, overall, TJA patients are more likely to adhere NNGB than a representative sample of persons >40 years from the Dutch general population.
