The Impact of Hospital Size and Teaching Status on Outcomes Following Total Ankle Arthroplasty

The popularity and utilization of total ankle arthroplasty (TAA) as treatment for ankle arthritis has increased exponentially from 1998 to 2012. Overall the outcomes have improved for TAA with the introduction of new-generation implants and this has increased the focus on optimizing other variables affecting outcomes for TAA. The purpose of this study was to examine the effects of hospital characteristics and teaching status on outcomes for TAA.

Does Medicaid payer status affect patient's shoulder outcomes after shoulder arthroplasty?

Low socioeconomic status and Medicaid insurance as a primary payer have been shown to influence resource utilization and risk-adjusted outcomes for total joint arthroplasty. The purpose of this study was to assess the effects of Medicaid primary payer status on outcomes following shoulder arthroplasty (SA).

3D preoperative planning for humeral head selection in total shoulder arthroplasty

Recreation of glenohumeral biomechanics and humeral anatomy has been shown to improve outcomes in shoulder arthroplasty. Recent research has focused on utilizing simulation software and intraoperative instrumentation to improve glenoid implant selection and positioning, but no study had evaluated the reliability of new features in 3D preoperative planning software for humeral planning in total shoulder arthroplasty.

Comparison of Microbial Count on Various Surfaces in Operating Rooms at Different Times of the Day

The purpose of this study was to determine the degree of microbial contamination of surfaces in the operating room (OR) and to understand the relationship between time and location of contamination. Five OR surfaces were sampled at two time points on three consecutive Mondays and Thursdays. Each sample was cultured on a blood agar plate and introduced to a liquid nutrient broth.

Efficacy of Imaging Modalities Assessing Fatty Infiltration in Rotator Cuff Tears.

Fatty atrophy is a diagnosis characterized by the combination of fatty infiltration and muscle atrophy of the rotator cuff. Studies have shown a strong positive correlation between the level of fatty infiltration and the risk of experiencing a chronic rotator cuff tear. Therefore, the purpose of the present study was to review the current literature on radiographic imaging of fatty infiltration and fatty atrophy to better aid surgeons in predicting functional outcome and to help guide patient decisions.
