Comparison of Early Postoperative Step and Stair Counts With the Direct Anterior Approach Versus the Posterior Approach for Total Hip Arthroplasty.

Background: The purpose of this study was to evaluate the impact of direct anterior approach (DAA) or posterior approach (PA) on step and stair counts after total hip arthroplasty using a remotely monitored mobile application with a smartwatch while controlling for baseline characteristics.

Methods: This is a secondary data analysis from a prospective cohort study of patients utilizing a smartphone-based care management platform. The primary outcomes were step and stair counts and changes from baseline through one year.

Evaluation of weight loss counsel for Osteoarthritis patients: A cross-sectional analysis of NHANES 2011-2018.

Objective: Though health care providers (HCPs) know the importance of weight loss counsel for Osteoarthritis (OA), little is known about how frequently it is practiced and even less of its effectiveness. Thus, we analyzed the prevalence and effectiveness of weight counsel receipt in overweight/obese OA patients.

Design: Using 2011-2018 National Health and Nutrition Examination Survey data, we cross-sectionally analyzed overweight/obese patients in the United States to determine the prevalence of receipt of HCP weight counsel in those with OA and among other variables.

Analyzing the Quality and Readability of Online Hyaluronic Acid Knee Injection Resources.

Introduction: We analyzed the quality of information about Hyaluronic acid (HA) knee injections for osteoarthritis using DISCERN, a tool that grades the quality of websites. We also analyzed readability with Flesch-Kincaid grade reading levels (FKGRL).

Methods: Lists of the top ten included sites from Google searches about HA injections were evaluated using DISCERN to determine their quality.

Femoral Condyle Insufficiency Fracture After Total Knee Arthroplasty Using a Stemless Femoral Component With a Midlevel Constraint Articular Surface.

Midlevel constraint prostheses have provided increased varus/valgus and rotational stability for patients with severe deformity or ligamentous instability undergoing total knee arthroplasty (TKA). Here we present a series of 5 patients, 2 in detail, who underwent a primary TKA with a midlevel constraint articular surface and a primary femoral component without stem extension who all suffered isolated medial femoral condyle insufficiency fractures. All 5 TKAs were performed in females with both preoperative valgus deformity and flexion contractures.

Success of Various Marketing Strategies for a New-to-the-Area Orthopedic Practice.

Background Competition for patients among orthopaedic private practices, multi-specialty groups, and hospital systems continues to persist. An effective marketing campaign is essential for a practice to succeed in this competitive environment. The purpose of this study was to investigate the cost-effectiveness and efficacy of each marketing campaign and the influence of patient demographics on efficacy.

Improved accuracy and reproducibility of a novel CT-free robotic surgical assistant for medial unicompartmental knee arthroplasty compared to conventional instrumentation: a cadaveric study.

Purpose: Alignment errors in medial unicompartmental knee arthroplasty (UKA) predispose to premature implant loosening and polyethylene wear. The purpose of this study was to determine whether a novel CT-free robotic surgical assistant improves the accuracy and reproducibility of bone resections in UKA compared to conventional manual instrumentation.

Methods: Sixty matched cadaveric limbs received medial UKA with either the ROSA Partial Knee System or conventional instrumentation.

Patient Perception of Physician Attire in the Outpatient Setting During the COVID-19 Pandemic.

Introduction: In response to the SARS-CoV-2 pandemic, physician attire has evolved to incorporate personal protective equipment (PPE). Although PPE is mandated for all healthcare workers, variability exists in choice and availability. The purpose of this study was to determine patient perception of physician attire during the COVID-19 pandemic in an outpatient setting.

2021 John N. Insall Award: Aspirin is effective in preventing propagation of infrapopliteal deep venous thrombosis following total knee arthroplasty.

Aims: The optimal management of an infrapopliteal deep venous thrombosis (IDVT) following total knee arthroplasty (TKA) remains unknown. The risk of DVT propagation and symptom progression must be balanced against potential haemorrhagic complications associated with administration of anticoagulation therapy. The current study reports on a cohort of patients diagnosed with IDVT following TKA who were treated with aspirin, followed closely for development of symptoms, and scanned with ultrasound to determine resolution of IDVT.

Better accuracy and reproducibility of a new robotically-assisted system for total knee arthroplasty compared to conventional instrumentation: a cadaveric study.

Purpose: Robotically-assisted total knee arthroplasty (TKA) has been shown to improve alignment and decrease outliers, an important goal in TKA procedures. The purpose of this cadaveric study was to compare the accuracy and reproducibility of a recently introduced TKA robotic system to conventional instrumentation for bone resections.

Methods: This cadaveric study compared 14 robotically-assisted TKA with 20 conventional TKAs.
