Synopsis

Keywords: Data Analysis, OsteoarthritisThe purpose of this study was to investigate whether prolonged overexertion can lead to cartilage degeneration through Synthetic MRI derived relaxation maps. In this study, 30 participants were recruited and measured with T1 and T2 mapping derived by Synthetic MRI. There was a statistically significant trend in cartilage T1 and T2 values in the long-term exercise group compared to the normal exercise group. Based on altered T1 and T2 relaxation properties of cartilage tissues, we conclude that chronic overexercise may lead to cartilage degeneration.
