Synopsis

Magnetic resonance imaging (MRI) is the preferred choice for evaluating knee joint injury, which commonly occurs during physical training. In this study, we compared the effects of long-walking and regular daily training on knee joint injuries and cartilage microstructure in 23 young freshmen by analyzing 3D-DESSWE and T2 mapping images using the automatic cartilage segmentation prototype software. Our results demonstrated that regular daily training strengthens the knee joints and protects against knee joint injury by increasing the volume of the knee cartilage. Moreover, knee joint injury caused by short-term long walking and high-intensity pull training was reversible.
