Parkland Trauma Index of Mortality: Real-Time Predictive Model for Trauma Patients.

Objective: Vital signs and laboratory values are used to guide decisions to use damage control techniques in lieu of early definitive fracture fixation. Previous models attempted to predict mortality risk but have limited utility. There is a need for a dynamic model that captures evolving physiologic changes during a trauma patient's hospital course.

The effect of age on risk of retear after rotator cuff repair: a systematic review and meta-analysis.

Hypothesis: The purpose of this study was to perform a systematic review and meta-analysis to determine the effect of age on rotator cuff repair failure. The hypothesis of this study was that increased patient age would lead to a higher rate of retears and/or repair failures after rotator cuff repair.

Methods: We conducted a systematic review and meta-analysis of level I and II studies evaluating patients undergoing rotator cuff repair that also included an imaging assessment of the structural integrity of the repair.

Staged vs Concurrent Hardware Removal During Conversion Total Knee Arthroplasty.

Background: Conversion total knee arthroplasty (TKA) in the presence of periarticular hardware can be associated with increased resource utilization, complications, and revisions. However, little guidance exists on the optimal approach to hardware removal. The purpose of this study is to compare outcomes of conversion TKA with hardware removal performed in either a staged or concurrent manner.

In Vivo analysis of spinopelvic kinematics and peak head-cup contact in total hip arthroplasty patients with lumbar degenerative disc disease.

Anterior instability after total hip arthroplasty (THA) has been described in patients with thoracolumbar kyphotic deformity. Although compensatory posterior pelvic tilt with subsequent increased functional anteversion has been described as the mechanism, there is a paucity of in vivo data. The purpose of our study was to compare pelvic tilt, anteversion, inclination, and position of head-cup contact points in patients with lumbar degenerative disc disease (DDD) and a matched patient cohort without DDD.

Tranexamic acid administration for anatomic and reverse total shoulder arthroplasty: a systematic review and meta-analysis.

Background: Tranexamic acid (TXA) has been shown to reduce perioperative blood loss and risk of blood transfusion. Evidence establishing its efficacy in total shoulder arthroplasty (TSA) is limited. The current study evaluated the effect of TXA on perioperative blood loss and transfusion risk after TSA.

Venous Thromboembolism Prophylaxis after Total Knee Arthroplasty.

Venous thromboembolic disease (VTED) is a major cause of morbidity and mortality after total knee arthroplasty (TKA). Current VTED prophylaxis protocols consist of early mobilization, mechanical compression devices, and pharmacologic agents. Venous phasic flow-regulated below-knee devices are generally favored, but the optimal duration and method of mechanical prophylaxis is unknown.
