Abstract:

Cement fixation is considered the gold standard for total knee arthroplasty (tKA), in recent years, however, there has been a shift toward younger and heavier body weight populations, lifelong use of implants is a concern, cementless prostheses can achieve permanent biological fixation with bone, it can preserve bone mass and avoid the production of cement debris, reducing the occurrence of postoperative radiolucent lines. However, it is necessary to restrict weight bearing and high flexion activity in the early postoperative period, which is very unfavorable to the early rehabilitation of patients. In general, both bone cement and cementless prostheses have achieved good results in modern times, but both have certain shortcomings, and hybrid prostheses may improve the survival rate.

Key words: Arthroplasty, replacement, knee, Bone cements
