Purpose:
Although cement still represents the gold standard in total knee arthroplasty fixation, recent advances in implant design, materials, and coatings have led to a renewed interest in cementless fixation. Furthermore, a growing number of challenging patients, such as young and active or obese, are requiring a total knee arthroplasty procedure. This narrative review aims to outline technological advancements in cementless fixation and compare its outcomes with cemented fixation in the general population and focusing on young, active, and obese patients.
Methods:
A narrative review of the literature was performed with a primary search on Medline through PubMed. Articles regarding cementless fixation in total knee arthroplasty.
Conclusions:
Modern cementless prostheses are provided with optimized materials, coatings, and designs, offering improved integration and stability between the bone and the component. When compared to cemented fixation, modern cementless implants showed equal clinical outcomes and survivorship in the general population, while some specific patient groups such as young active individuals and obese individuals showed even superior outcomes.
