Personalized alignment in total knee arthroplasty reduces patellar tilt: A retrospective study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral kinematics is crucial for patient satisfaction following total knee arthroplasty (TKA). A postoperative patellar tilt greater than 5° has been associated with inferior clinical outcomes. While a femoral component external rotation beyond 3° is generally protective against patellar tilt, personalized alignment may not ...

Predicting the steady state thickness of passive films in order to prevent degradations of implant [PDF]

, 2013
Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un ...

Imageless and image‐based robotic‐assisted total knee arthroplasty achieve equivalent radiographic accuracy: A randomised controlled trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Robotic‐assisted total knee arthroplasty systems offer both image‐based and imageless workflows, but their comparative accuracy remains unclear. The robotic surgical assistant (ROSA) system uniquely provides both approaches within a single platform.

Impact of simultaneous exposure to RF and gradient electromagnetic fields on implant MR safety labeling

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To investigate whether heating contributions produced by radiofrequency (RF) and gradient fields superpose sufficiently at the worst‐case locations to justify their simultaneous consideration in magnetic resonance imaging (MRI) implant safety labeling.
