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 ...

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

Nano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.
