Magnetic Resonance Imaging Analysis Demonstrates Improved Reliability in Measuring Shoulder Glenoid Bone Loss Using a Two-Thirds Glenoid Height Technique Compared to the "Best-fit Circle".

Purpose: To evaluate the superior to inferior glenoid height as a reliable reference in best-fit circle creation for glenoid anatomy.

Methods: The morphology of the native glenoid was evaluated using magnetic resonance imaging (MRI) in patients without shoulder instability. Using T1 sagittal MRI images, 2 reviewers independently estimated glenoid size using the two-thirds technique and the "best-fit circle" technique at 2 different times.

Primary and Posttraumatic Knee Osteoarthritis in the Military.

Osteoarthritis is a particularly burdensome and career-limiting condition for military service members. The daily demands of military service place the service members at a baseline increased risk of developing primary OA as well as increased risk of acute knee injuries that further predispose to developing posttraumatic OA. There are multiple treatment options available for primary and posttraumatic OA from osteotomy to arthroplasty.

Functional outcomes following lateral ulnar collateral ligament reconstruction for symptomatic posterolateral rotatory instability of the elbow in an athletic population.

Hypothesis: The purpose of this investigation was to characterize the functional and surgical outcomes following lateral ulnar collateral ligament (LUCL) reconstruction for posterolateral rotatory instability in an athletic population.

Methods: All US military service members who underwent LUCL reconstruction between 2008 and 2013 were identified. A retrospective chart review was performed, and the prospective Mayo Elbow Performance Score and QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand questionnaire) score were obtained.
