Posterior-stabilized total knee arthroplasty (PS-TKA) is associated with high rates of
satisfaction and functional recovery. This is notably attributed to implant optimization in terms …

Fixation in cementless total knee arthroplasty is provided by osseous integration.
Radiography, radiostereometric analysis (RSA), and magnetic resonance imaging (MRI) …

Successful osseointegration of press-fit implants depends on the initial stability, often
measured by the micromotions between the implant and bone. A good primary stability can …

Background Cementless tibial baseplates in total knee arthroplasty include fixation features
(eg, pegs, spikes, and keels) to ensure sufficient primary bone-implant stability. While the …

The initial fixation of cementless tibial trays after total knee arthroplasty is critical to ensure
bony ingrowth and long-term fixation. Various fixed-bearing implant designs that utilize …

Background There has been a recent increase in the use of cementless fixation for primary
total knee arthroplasty. While the early results of contemporary cementless implants are …

Background Cementless total knee arthroplasty (TKA) has regained interest for its potential
for long-term biologic fixation. The density of the bone is related to its ability to resist static …

Micromotion exceeding 150 μm at the implant–bone interface may prevent bone formation
and limit fixation after cementless knee arthroplasty. Understanding the critical parameters …

Background Primary stability is of great importance for the longevity of the implant in
cementless revision total hip arthroplasty, since instability is a major cause of rerevision. The …

Résumé La prothèse totale de genou (PTG) postéro-stabilisée (PS) est associée à un haut
niveau de satisfaction et de retour fonctionnel des patients, ces résultats étant notamment …
