Chinese hospital masters 3D printed tantalum knee implants
The incidence of osteoarthritis among Chinese is about 2.2 to 3.5 percent, with an upward trend. The First Hospital affiliated to Army Medical University (AMU) so far has conducted 27 clinical trials on knee implants based on customized 3D-printed porous tantalum. After 3D CT scan of a patient’s bone and bone defects, it takes only 72 hours to design a porous tantalum implant and 3D print the customized implant.
