Abstract:: Abstract: After introducing the pros and cons of autograft and conventional prosthetic joint replacement, the merits of 3D printing technology are analyzed. Although 3D printing technology has the advantages of precise preoperative design to simulate the anatomical shape, intraoperative navigation to reduce bleeding, and 3D printed prosthesis of porous structure to facilitate bone ingrowth, it involves several problems, such as printing materials, ethics and poor mechanical strength. With the advancement of technology and material science, using 3D printing technology to print out bioactive artificial joints will definitely be a new trend in the future development of orthopedics.
