Abstract
Objectives: To quantify physical activity 32-37 years after acute anterior cruciate ligament injury with respect to the World Health Organization physical activity recommendation, and to compare physical activity levels between: i) individuals managed with anterior cruciate ligament surgery and rehabilitation vs. rehabilitation alone, and ii) individuals with and without symptomatic osteoarthritis.
Design: Prospective longitudinal cohort.
Methods: Participants (n = 234) within 14 days of anterior cruciate ligament rupture (confirmed arthroscopically) were allocated to early anterior cruciate ligament repair and rehabilitation or rehabilitation alone. Thirty-two to 37 years after anterior cruciate ligament injury, 80 participants provided valid accelerometer data assessing physical activity and underwent an x-ray to assess osteoarthritis. Symptomatic osteoarthritis was defined as radiographic osteoarthritis plus knee pain and/or symptoms. Differences in physical activity parameters between treatment and osteoarthritis groups were assessed with analysis of covariance, adjusted for potential confounding.
Results: Tibiofemoral symptomatic osteoarthritis was observed in 35 (47 %) participants (anterior cruciate ligament surgery 44 %; rehabilitation-alone 50 %). Participants spent a mean of 37.1 (95 % confidence interval 31.6-42.6) min/day in moderate to vigorous physical activity. Recommended levels of physical activity (≥150 min/week of moderate to vigorous physical activity) were reached by 66 % of participants with tibiofemoral symptomatic osteoarthritis [mean (95 % confidence interval): 35.4 (26.2-44.7) min/day of moderate to vigorous physical activity] and 77 % without tibiofemoral symptomatic osteoarthritis [39.1 (31.5-46.8) min/day moderate to vigorous physical activity]. Adjusted analyses found no differences in physical activity parameters between treatment groups or between participants with or without tibiofemoral symptomatic osteoarthritis.
Conclusions: More than 30 years after anterior cruciate ligament injury, over two-thirds of participants reached recommended levels of physical activity. Physical activity levels did not differ based on the initial treatment strategy or presence of tibiofemoral symptomatic osteoarthritis.
期刊介绍:
The Journal of Science and Medicine in Sport is the official journal of Sports Medicine Australia (SMA) and is an an international refereed research publication covering all aspects of sport science and medicine.
The Journal considers for publication Original research and Review papers in the sub-disciplines relating generally to the broad sports medicine and sports science fields: sports medicine, sports injury (including injury epidemiology and injury prevention), physiotherapy, podiatry, physical activity and health, sports science, biomechanics, exercise physiology, motor control and learning, sport and exercise psychology, sports nutrition, public health (as relevant to sport and exercise), and rehabilitation and injury management. Manuscripts with an interdisciplinary perspective with specific applications to sport and exercise and its interaction with health will also be considered.
