Abstract
Purpose: Although several studies have examined the relationship between physical activity and knee osteoarthritis, the effect of
physical activity on knee joint health is unclear. The aim of this systematic review was to examine the relationships between physical
activity and individual joint structures at the knee. Methods: Computer-aided searches were conducted up until November 2008, and the
reference lists of key articles were examined. The methodological quality of selected studies was assessed based on established criteria,
and a best-evidence synthesis was used to summarize the results. Results: We found that the relationships between physical activity
and individual joint structures at the knee differ. There was strong evidence for a positive association between physical activity and
tibiofemoral osteophytes. However, we also found strong evidence for the absence of a relationship between physical activity and joint
space narrowing, a surrogate method of assessing cartilage. Moreover, there was limited evidence from magnetic resonance imaging
studies for a positive relationship between physical activity and cartilage volume and strong evidence for an inverse relationship between
physical activity and cartilage defects. Conclusions: This systematic review found that knee structures are affected differently by
physical activity. Although physical activity is associated with an increase in radiographic osteophytes, there was no related increase in
joint space narrowing, rather emerging evidence of an associated increase in cartilage volume and decrease in cartilage defects
on magnetic resonance imaging. Given that optimizing cartilage health is important in preventing osteoarthritis, these findings indicate
that physical activity is beneficial, rather than detrimental, to joint health.
