Impact of femoro-tibial size combinations and TKA design on kinematics
The variability in patients’ femoral and tibial anatomy requires to use different tibia component sizes with the same femoral component size. These size combinations are allowed by manufacturers, but the clini...

TKA design-integrated trochlea groove rotation reduces patellofemoral pressure
Total knee arthroplasty (TKA) leaves 11–25% of the patients unsatisfied, and patellofemoral joint pain is one cause. This study aimed to compare the differences between kinematics and load transfer in the same...

Periprosthetic bone remodelling of short-stem total hip arthroplasty: a systematic review
Short-stem hip arthroplasty (SHA) was designed to preserve bone stock and provide an improved load transfer. To gain more evidence regarding the load transfer, this review analysed the periprosthetic bone remo...

Medial stabilized and posterior stabilized TKA affect patellofemoral kinematics and retropatellar pressure distribution differently
Patellofemoral kinematics and retropatellar pressure distribution change after total knee arthroplasty (TKA). It was hypothesized that different TKA designs will show altered retropatellar pressure distributio...

Influence of mediolateral tibial baseplate position in TKA on knee kinematics and retropatellar pressure
Anterior knee pain is a major reason for unsatisfied patients after total knee arthroplasty (TKA). Since malposition and increased retropatellar peak pressure are supposed to contribute to pain, we conducted t...
