Long-term Outcomes After Total Ankle Arthroplasty: A Systematic Review.

Background: Total ankle arthroplasty has emerged as a treatment to successfully treat ankle arthritis. Recent studies have reported more than 40 000 total ankle arthroplasties (TAAs) being performed between 2009 and 2019 in the United States. Although recent studies have reported favorable patient-reported outcomes at short- and midterm follow-up, there is a paucity of aggregate literature reporting on long-term patient-reported outcomes (PROs) after TAA.

Nanocomposites with increased energy density through high aspect ratio PZT nanowires.

High energy storage plays an important role in the modern electric industry. Herein, we investigated the role of filler aspect ratio in nanocomposites for energy storage. Nanocomposites were synthesized using lead zirconate titanate (PZT) with two different aspect ratio (nanowires, nanorods) fillers at various volume fractions dispersed in a polyvinylidene fluoride (PVDF) matrix.
