NCT04954482

Brief Summary

To establish a III°PCL injury model on fresh cadaver knee specimens, and to define the pathological and anatomical connotation of III°PCL injury by using anatomical methods. To explore and establish combined reconstruction techniques, including PCL reconstruction combined with injury repair and reconstruction, and to explore the role of combined reconstruction techniques in maintaining knee stability through biomechanical experiments.
