The use of a more compliant material, such as polyetheretherketone (PEEK), for a
cementless femoral component is a potential solution to prevent aseptic loosening caused …

This study investigated the fixation of a cemented PEEK femoral TKA component. PEEK and
CoCr implants were subjected to a walking gait cycle for 10 million cycles (MC), 100,000 …

Cementless femoral total knee arthroplasty (TKA) components use a press-fit (referred to as
interference fit) to achieve initial fixation. A higher interference fit could lead to a superior …

Computational models have been widely used for more than four decades to evaluate the
mechanical behavior of knee joint arthroplasty. Validated computational models provide a …

It is essential to calculate micromotions at the bone-implant interface of an uncemented
femoral total knee replacement (TKR) using a reliable computational model. In the current …

Background and objective Obesity is one of the risk factors for osteoarthritis. The end-stage
treatment for osteoarthritis is total knee arthroplasty (TKA). However, it remains controversial …

Background During implantation of an uncemented femoral knee implant, press-fit
interference fit provides the primary stability. It is assumed that during implantation a …

Improper osteotomy during total knee arthroplasty (TKA) can lead to anterior femoral
notching, which increases the risk of periprosthetic fractures due to stress concentration …

Aims This study aimed to investigate the optimal sagittal positioning of the uncemented
femoral component in total knee arthroplasty to minimize the risk of aseptic loosening and …

Aseptic loosening is the primary cause of revision in cementless total knee arthroplasty
(TKA), emphasizing the importance of strong initial stability for long-term implant success …
