Joint implants are generally divided into bone cement fixation type and biological fixation type. Biological fixation type joint prosthesis is welcomed by many patients and doctors because of its advantages such as relatively simple operation and the fixation effect will not weaken with time. 

Tantalum metal joint implant is a kind of biostationary prosthesis, also known as bone trabecular metal, which provides high friction force at the bone-prosthesis interface through good friction fit and initial implant stability. In addition, its high porosity and supporting structure provide extensive bone ingress, ensuring the prosthesis's long-term fixation.
