The Production Technology Department of Guangzhou Sailong completed the delivery of tantalum knee pads from Southwest Hospital

Entrusted by Southwest Hospital, Guangzhou Sailong completed the delivery of a personalized tantalum metal knee joint filler.This case was an internal femoral condyle infarction of the left knee, which was repaired by filling with porous tantalum metal pad.The porous trabecular biomimetic structure of bone has the advantages of large contact area, good mechanical properties and biocompatibility, and elastic modulus similar to human bone, which can ensure the long-term stability of the prosthesis after implantation.The joint contact surface is polished by the solid design surface, which can effectively reduce the friction of the joint surface and ensure the smooth contact surface.

The filling pad was formed by Sailong's self-developed selective electron beam melting 3D printing technology. The material was tantalum, which is the most biocompatible metal among known metal materials. The printing time was 8h, after post-treatment, the tantalum knee pad was successfully delivered to Southwest Hospital (The Production Technology Department of Guangzhou Sailong /Zheng Kaibiao)
