Role of Depression in Total Knee Arthroplasty: A Retrospective Analysis of Perioperative Outcomes in Patients in the United States.

We evaluate the patient demographics, perioperative outcomes, in-hospital complications, and assess recent national trends in clinically depressed and non-depressed patients undergoing primary total knee arthroplasty (TKA). Using the National Hospital Discharge Survey from 2001 and 2010, patients undergoing primary TKA in the United States were identified based upon the diagnosis of depression. Differences in gender, patient-demographics, comorbidities, complications, length of stay, and discharge disposition were analyzed.

A novel method for predicting superior gluteal nerve safe zones in the lateral approach to the hip.

Introduction: The superior gluteal nerve (SGN) is at risk for laceration during lateral approach total hip arthroplasty (THA). The purpose of this study is to assess the accuracy of the trochanter-to-iliac crest distance (TCD) and the nerve-to-trochanter distance (NTD) ratio in determining a reproducible safe zone around the SGN independent of height.

Materials And Methods: Eighteen hemipelvises were dissected and the SGNs were exposed.

The Role of Patient Education in Arthritis Management: The Utility of Technology.

Technologies continue to shape the path of medical treatment. Orthopedic surgeons benefit from becoming more aware of how twenty-first century information technology (IT) can benefit patients. The percentage of orthopedic patients utilizing IT resources is increasing, and new IT tools are becoming utilized.

The ratio of patient body mass index to age: a cost-effective implant selection guideline for total knee arthroplasty.

Background: We sought to develop an objective implant selection guideline based on the ratio of patient body mass index (BMI) to age in order to select implants preoperatively and reduce cost while maintaining quality. The BMI-to-age ratio can be used to distinguish patient demand and select those patients who may benefit from newer technology and higher cost implants and those who would do well with standard-demand implants.

Methods: A retrospective analysis investigated the types of implants received by patients undergoing total knee arthroplasty from January 2012 to August 2014.

Variance in predicted cup size by 2-dimensional vs 3-dimensional computerized tomography-based templating in primary total hip arthroplasty.

Background: Preoperative total hip arthroplasty templating can be performed with radiographs using acetate prints, digital viewing software, or with computed tomography (CT) images. Our hypothesis is that 3D templating is more precise and accurate with cup size prediction as compared to 2D templating with acetate prints and digital templating software.

Methods: Data collected from 45 patients undergoing robotic-assisted total hip arthroplasty compared cup sizes templated on acetate prints and OrthoView software to MAKOplasty software that uses CT scan.

The utility of bicruciate-retaining total knee arthroplasty.

Background: We describe the features of modern and historical bicruciate-retaining (BCR) total knee arthroplasty (TKA) implants compared with other TKA implant designs, reviewing kinematics, proprioception, operative technique, and clinical results.

Methods: We performed a review based on PubMed, Embase, CINAHL Plus, and Cochrane databases from January 1990 to April 2016 using combinations of the following keywords: "bicruciate-retaining arthroplasty," "bicruciate-retaining total knee arthroplasty," "bicruciate-retaining TKA," "kinematics," "knee kinematics," and "TKA kinematics."

Results: Four studies have supported the notion that preservation of both cruciate ligaments in TKA preserves more "normal" knee kinematics.

Strategies to Prevent Periprosthetic Joint Infection After Total Knee Arthroplasty and Lessen the Risk of Readmission for the Patient.

There is yet to be a standardized total knee arthroplasty (TKA) surgical protocol that has been studied to a sufficient degree to offer evidence-based practices regarding infection and readmission prevention. Although high-level evidence is often sought to provide guidance concerning protocol- and process-level decisions, the literature is often confusing and nondefinitive in its conclusions and recommendations regarding periprosthetic joint infection and readmission prevention. Areas of study that require further investigation include the following: the role of patient optimization and preoperative mitigation of risk; perioperative antibiotics; operating room environment; blood management; operative techniques, implants, and infection prevention measures; wound care management; and post acute care.

Importance of Proper Utilization of International Classification of Diseases 10th Revision and Clinical Documentation in Modern Payment Models.

Background: Health care payment models are changing rapidly, and the measurement of outcomes and costs is increasing.

Methods: With the implementation of International Classification of Diseases 10th revision (ICD-10) codes, providers now have the ability to introduce a precise array of diagnoses for their patients.

Results: More specific diagnostic codes do not eliminate the potential for vague application, as was seen with the utility of ICD-9.
