The significant effect of the medial hamstrings on dynamic knee stability.

Purpose: While hamstring autograft is a popular option for the general population, BTB autograft is still significantly more popular among professional athletes due to concerns of altering knee kinematics with hamstring harvest. This study seeks to quantify the contribution of the medial hamstrings to knee stability.

Methods: Valgus knee laxity, anterior tibial translation, and rotational motion were measured in eight fresh-frozen cadaveric knees after forces were applied on the tibia in each plane (coronal, sagittal, and axial).

Comparison of perioperative complications after total elbow arthroplasty in patients with and without diabetes.

Background: Few studies have analyzed the effect of diabetes on outcomes after total elbow arthroplasty (TEA). We investigated the perioperative complications after TEA in patients with and without diabetes.

Methods: We evaluated the Nationwide Inpatient Sample (NIS) database from 2005 to 2010 for patients who underwent a TEA.

Analysis of perioperative complications in patients after total shoulder arthroplasty and reverse total shoulder arthroplasty.

Background: Data directly comparing the perioperative complication rates between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA) are limited.

Methods: The Nationwide Inpatient Sample database, which comprises data from a statistically representative sample of hospitals across the United States, was analyzed for the years 2010 and 2011. The International Classification of Diseases, Ninth Revision procedure codes differentiated the patients who received TSA (81.
