Physical activity increases synovial fluid in ankle tendon sheaths: an adjustment of MR Criteria is needed

ConclusionData pre and post-running show a trend of increasing synovial fluid, however, not significant for each individual tendon. The pooled data for all tendons, (n = 800) show a statistically significant increase after running (p <  0.001). The clinical implication is that the threshold for normally acceptable fluid should be adjusted if the patient undergoes an MR study after recent physical activity.
