Flatfoot arch correction with generic 3D-printed orthoses at different body weight percentages.

Background: Flatfoot can be associated with foot pathologies and treated conservatively with foot orthoses to correct arch collapse and alleviate painful symptoms. Recently, 3D printing has become more popular and is widely used for medical device manufacturing, such as orthoses. This study aims at quantifying the effect of generic 3D-printed foot orthoses on flatfoot arch correction under different static loading conditions.

Traffic Cameras-An Effective and Sustainable Method of Reducing Traffic and Airborne Particles During Arthroplasty Surgery.

Background: Traffic in the operating room (OR) create turbulence and contaminates air by bacterial shedding. Therefore, we examined: (1) if the number and duration of door openings were associated with increased particles during arthroplasty surgery; (2) if traffic cameras installed in the operating room were an effective intervention to decrease traffic and particles during arthroplasty surgery; and (3) the effectiveness of traffic camera over time.

Methods: Fifty cases were included between November 3, 2021, and June 22, 2022, with 25 cases in each group.
