Occupational Outcomes and Revision Rates for Medial Unicondylar Knee Arthroplasty in U.S. Military Servicemembers.

This study evaluates return to work and revision rates for medial unicondylar knee arthroplasty (UKA) in a high-demand military cohort. Patient demographic and clinical variables were isolated from the medical records of active-duty military servicemembers with at least 2 years of postoperative follow-up and correlated with return to work, medial UKA survivorship, and perioperative complications. The medial UKA annual revision rate was calculated as the percentage of implants revised per observed component year.

The Shift to Same-Day Outpatient Joint Arthroplasty: A Systematic Review.

Background: Hip and knee arthroplasties length of stay continues to shorten after advances in perioperative and intraoperative management, as well as financial incentives. Some authors have demonstrated good results with outpatient arthroplasty, but safety and general feasibility of such procedures remain unclear. Our hypothesis is that outpatient arthroplasty would demonstrate higher readmission and complication rates than inpatient arthroplasty.

Intraoperative fluoroscopy with a direct anterior approach reduces variation in acetabular cup abduction angle.

Introduction: The purpose of this study was to compare acetabular cup position for 2 cohorts of total hip arthroplasty (THA) patients who had a direct anterior approach.

Methods: 100 THA cases were performed with an anterior approach using intraoperative fluoroscopy (IF) to aid in cup positioning. Another group of 100 cases underwent THA with an anterior approach without the use of any fluoroscopy.

Predictors of hospital readmission following revision total knee arthroplasty.

Purpose: Hospital readmission is emerging as an important quality measure, yet modifiable predictors of readmission remain unknown. This study was designed to identify risk factors for readmission following revision total knee arthroplasty.

Methods: The National Surgical Quality Improvement Program dataset was queried to identify patients undergoing revision total knee arthroplasty from 2011 to 2012.

Postoperative myocardial infarction and cardiac arrest following primary total knee and hip arthroplasty: rates, risk factors, and time of occurrence.

Background: Cardiac complications are a major cause of postoperative morbidity. The purpose of this study was to determine the rates, risk factors, and time of occurrence for cardiac complications within thirty days after primary unilateral total knee arthroplasty and total hip arthroplasty.

Methods: The American College of Surgeons National Surgical Quality Improvement Program data set from 2006 to 2011 was used to identify all total knee arthroplasties and total hip arthroplasties.

The Influence of Musculoskeletal Conditions, Behavioral Health Diagnoses, and Demographic Factors on Injury-Related Outcome in a High-Demand Population.

Background: The extent to which musculoskeletal injuries and sociodemographic factors impact long-term outcome remains unknown. The purpose of this study was to provide a prognostic analysis of the influence of musculoskeletal conditions, behavioral health diagnoses, and patient-based characteristics on outcomes among a longitudinal cohort.

Methods: This is a longitudinal observational study of the population of an Army brigade deployed to Iraq from 2006 to 2007.

Morbidity and mortality in the thirty-day period following total hip arthroplasty: risk factors and incidence.

The study sought to ascertain the incidence rates and risk factors for 30-day post-operative complications after primary total hip arthroplasty (THA). Complications were categorized as systemic or local and subcategorized as major or minor. There were 17,640 individuals who received primary THA identified from the 2006-2011 ACS NSQIP.

Thirty-day postoperative complications and mortality following total knee arthroplasty: incidence and risk factors among a national sample of 15,321 patients.

Background: The purpose of this investigation was to determine the incidence rates of, and identify risk factors for, thirty-day postoperative mortality and complications among more than 15,000 patients who underwent a primary unilateral total knee arthroplasty as documented in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).

Methods: The NSQIP database was queried to identify patients who had undergone primary unilateral total knee arthroplasty between 2006 and 2010. Patient demographics, medical history, and surgical characteristics were recorded, as were thirty-day postoperative complications, mortality, and length of hospital stay.

Non-emergent orthopaedic injuries sustained by soldiers in Operation Iraqi Freedom.

Background: The majority of soldiers deployed to the theater of combat operations return safely after completion of the deployment. Many of these soldiers sustain non-emergent musculoskeletal injuries that initially are treated nonoperatively and ultimately require surgery following their combat tour.

Methods: A prospective evaluation of the orthopaedic surgery consultations and surgical procedures required by soldiers returning from a full combat deployment was performed.

Burden of musculoskeletal disease and nonbattle nontraumatic injury in both war and disaster zones.

Disasters, both man-made and natural, are a known cause of morbidity and mortality among vulnerable populations. The initial phase of public health response typically addresses immediate traumatic injury or death in the wake of a disaster. However, little is known about the magnitude and cost of subsequent nontraumatic injury and illness in disaster zones.

HNO and NO release from a primary amine-based diazeniumdiolate as a function of pH.

The growing evidence that nitroxyl (HNO) has a rich pharmacological potential that differs from that of nitric oxide (NO) has intensified interest in HNO donors. Recently, the diazeniumdiolate (NONOate) based on isopropylamine (IPA/NO; Na[(CH(3))(2)CHNH(N(O)NO)]) was demonstrated to function under physiological conditions as an organic analogue to the commonly used HNO donor Angeli's salt (Na(2)N(2)O(3)). The decomposition mechanism of Angeli's salt is dependent on pH, with transition from an HNO to an NO donor occurring abruptly near pH 3.

Epidemiology of psychiatric disorders sustained by a U.S. Army brigade combat team during the Iraq War.

Objective: This study was designed to describe the epidemiology of psychiatric illnesses experienced by soldiers in a combat environment, which has been previously underreported.

Methods: A U.S.

Combat musculoskeletal wounds in a US Army Brigade Combat Team during operation Iraqi Freedom.

Background: A prospective, longitudinal analysis of musculoskeletal combat injuries sustained by a large combat-deployed maneuver unit has not previously been performed.

Methods: A detailed description of the musculoskeletal combat casualty care statistics, distribution of wounds, and mechanisms of injury incurred by a US Army Brigade Combat Team during "The Surge" phase of Operation Iraqi Freedom was performed using a centralized casualty database and an electronic medical record system.

Results: Among the 4,122 soldiers deployed, there were 242 musculoskeletal combat wounds in 176 combat casualties.

Disease and nonbattle injuries sustained by a U.S. Army Brigade Combat Team during Operation Iraqi Freedom.

Background: A longitudinal cohort analysis of disease nonbattle injuries (DNBI) sustained by a large combat-deployed maneuver unit has not been performed.

Methods: A descriptive analysis was undertaken to evaluate for DNBI casualty care statistics incurred by a U.S.

Characterization of combat-related spinal injuries sustained by a US Army Brigade Combat Team during Operation Iraqi Freedom.

Background Context: The United States is presently engaged in the largest scale armed conflict since Vietnam. Despite recent investigations into the scope of injuries sustained by soldiers in Iraq and Afghanistan, little information is available regarding the incidence and epidemiology of spine trauma in this population.

Purpose: Characterize the incidence and epidemiology of spinal injuries sustained during combat by soldiers of a US Army Brigade Combat Team (BCT) that participated in Operation Iraqi Freedom.
