Genicular Artery Embolization: A Promising Treatment Option for Recurrent Effusion Following Total Knee Arthroplasty.

Background: Selective genicular artery embolization (GAE) has shown promise as a minimally invasive treatment option for persistent symptomatic recurrent effusions (REs) following total knee arthroplasty (TKA).

Purpose: We sought to investigate the radiographic and clinical success of GAE for RE after TKA.

Methods: We performed a retrospective review of prospectively collected data on primary and revision TKA patients with RE, both hemorrhagic and non-hemorrhagic, who underwent GAE between 2019 and 2021 with a minimum of 6-month follow-up.

Social Risk Determinants for Successful Same Calendar Day Discharge in Total Joint Arthroplasty.

Background: While many studies have examined the impact of comorbidities on the success of same calendar day discharge (SCDD) in total joint arthroplasty (TJA), literature surrounding the impact of social determinants is lacking.

Purpose: We sought to investigate the relationship between various social determinants and success of SCDD after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods: We conducted a retrospective review of 1160 THA and 1813 TKA performed at a single academic institution between November 2020 and August 2022.

Success of Same-Day Discharge Total Hip and Knee Arthroplasty: Does Location Matter?

Background: Same calendar day discharge (SCDD) following total joint arthroplasty is desirable for patients and surgeons alike. The aim of this study was to compare the success rate of SCDD in an ambulatory surgical center (ASC) versus hospital setting.

Methods: A retrospective analysis was performed on 510 patients who underwent primary hip and knee total joint arthroplasty over a 2-year period.

Primary Cementless Femoral Stems in Conversion Hip Arthroplasty After Failed Fixation of Intertrochanteric Fractures.

Salvage conversion hip arthroplasty is a viable solution to restore function and reduce pain after failed intertrochanteric hip fracture fixation. Our primary objective was to assess early outcomes achieved with primary cementless metaphyseal-engaging femoral stems for conversion hip arthroplasty compared with revision diaphyseal-engaging stems. This was a retrospective review of 70 patients with failed intertrochanteric hip fractures subsequently managed with conversion total hip arthroplasty or hemiarthroplasty.

A Role for Outpatient Total Joint Arthroplasty During the COVID-19 Pandemic.

Outpatient total joint arthroplasty (TJA) gained favor during the COVID-19 pandemic. Our objective was to critically evaluate the safety and short-term outcomes of outpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA) throughout the pandemic compared with pre-pandemic given their increased use. This was a retrospective review of 941 patients who underwent elective, outpatient TKA and THA at a single institution.

Discrepancies in Work-Family Integration Between Female and Male Orthopaedic Surgeons.

Background: Female surgeons, representing 6.5% of the American Academy of Orthopaedic Surgeons, are particularly vulnerable to work-family conflict. This conflict may deter women from considering orthopaedic surgery as a specialty.

Distinct requirements for the COMPASS core subunits Set1, Swd1, and Swd3 during meiosis in the budding yeast Saccharomyces cerevisiae.

Meiosis-specific chromatin structures, guided by histone modifications, are critical mediators of a meiotic transient transcription program and progression through prophase I. Histone H3K4 can be methylated up to three times by the Set1-containing COMPASS complex and each methylation mark corresponds to a different chromatin conformation. The level of H3K4 modification is directed by the activity of additional COMPASS components.

The successful implementation of the Navio robotic technology required 29 cases.

Robotic-assisted total knee arthroplasty (RA-TKA) has potential benefits of improved restoration of mechanical alignment, accuracy of bony resection, and balancing. The purpose of this study was to determine the number of cases necessary for a single surgeon to achieve a constant, steady-state surgical time. The secondary purpose was to identify which steps demonstrated the most time reduced.

A Role for Modern Primary Cementless Femoral Stems in Revision Hip Arthroplasty.

Background: In revision total hip arthroplasty (THA) cases with preserved femoral metaphyseal bone, tapered proximally porous-coated "primary" femoral stems may be an option. The objective of this study was to compare outcomes of patients with Paprosky I or II femoral bone loss undergoing revision THA with either a primary metaphyseal-engaging cementless stem or a revision diaphyseal-engaging stem.

Methods: This was a retrospective analysis of 70 patients with Paprosky I or II femoral bone loss who underwent femoral revision.
