Meniscal stress response during tai chi yunshou movement by finite element analysis

Yunshou is a primary movement form of all kinds of Tai Chi, to which the meniscal stress response characteristic is not clear. This study applied finite element (FE) analysis with kinetic data to track the meniscal stress response during the typical Yunshou. The knee could flex with max angle of 58°, and move between left side 8° and right 9°. The movement out of the range increased the meniscal stress overall and stress concentration, implying meniscus injury risk. The FE model imported with kinetic data is good for investigating meniscal stress response during Tai Chi exercise.
