Randomized Controlled TrialCreep and Wear in Vitamin E-Infused Highly Cross-Linked Polyethylene Cups for Total Hip Arthroplasty: A Prospective Randomized Controlled Trial.
Aseptic loosening, the most common indication for revision surgery in total hip arthroplasty, can result from osteolysis caused by polyethylene (PE) wear particles. PE wear is increased by age-related oxidation of PE and free radicals emerging during irradiation cross-linking. Diffusion of vitamin E into PE stabilizes free radicals to maintain the biomechanical properties of PE. The purpose of this study was to determine whether vitamin E-infused highly cross-linked PE cups could reduce wear rates. ⋯ Therapeutic Level I.

Potential Sex Bias Exists in Orthopaedic Basic Science and Translational Research.
Potential sex bias has been shown in general surgery basic science and translational research, with unequal representation of male and female specimens. Because basic science research forms the foundation for clinical studies on which patient care is based, it is important that this research equally consider both sexes. The purpose of this study was to determine if potential sex bias exists in the basic science and translational orthopaedic literature. ⋯ Inequality in sex representation must be addressed as basic science and translational research creates the foundation for subsequent clinical research, which ultimately informs clinical care.

Randomized Controlled TrialRandomized Trial Comparing Suture Button with Single Syndesmotic Screw for Syndesmosis Injury.
This study compared clinical and radiographic results between patients who underwent stabilization of an acutely injured syndesmosis with a suture button (SB) and those treated with 1 quadricortical syndesmotic screw (SS). ⋯ Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.
