Utilization of Machine Learning Models to More Accurately Predict Case Duration in Primary Total Joint Arthroplasty.

Background: Accurate operative scheduling is essential for the appropriation of operating room esources. We sought to implement a machine learning model to predict primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) case time.

Methods: A total of 10,590 THAs and 12,179 TKAs between July 2017 and December 2022 were retrospectively identified.

Clinical outcomes of total joint arthroplasty in patients with bowel ostomies.

Introduction: The influence of prior colostomy or ileostomy on patients undergoing joint arthroplasty remains poorly understood. Our study aimed to assess whether patients with an ostomy undergoing hip and knee arthroplasties have worse postoperative outcomes and increased rates of revisions.

Method: A single-center, retrospective review of patients with a history of bowel ostomy who underwent a primary total hip arthroplasty (THA), hemiarthroplasty (HA), and total knee arthroplasty (TKA) from 2012 to 2021.

Comparison of trends of inpatient charges among primary and revision shoulder arthroplasty over a decade: a regional database study.

Background: This study examined trends in inpatient charges for primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA), hemiarthroplasty (HA), and revision total shoulder arthroplasty (revTSA) over the past decade.

Methods: The New York Statewide Planning and Research Cooperative System was queried for patients undergoing primary aTSA, rTSA, HA, and revTSA from 2010 to 2020 using International Classification of Diseases procedure codes. The primary outcome measured was total charges per encounter.

Clinical and Radiographic Outcomes of a Monoblock Fluted Titanium-Tapered Stem for Paprosky IIIa, IIIb, and IV Femoral Bone Defects.

Background: Modern fluted titanium-tapered stems (FTTS) have been increasingly utilized to achieve primary stability in conversion and revision total hip arthroplasty with major femoral bone loss. This study sought to determine the radiographic and clinical outcomes of a monoblock FTTS in patients who had major femoral bone loss.

Methods: A multicenter retrospective observational study of all total hip arthroplasty patients who received a monoblock FTTS who had up to 5-year radiographic follow-up was conducted.

Does Midcarpal Joint Structure Affect Development of Arthritis in the Wrist.

 Degenerative wrist arthritis develops in specific patterns because of forces acting on existing structural configurations. The most common pattern of wrist osteoarthritis is scapholunate advanced collapse (SLAC). Other patterns include isolated scaphotrapezial trapezoid (STT) joint and isolated midcarpal or radiolunate joint arthritis.

Does Surgical Approach to the Hip Play a Role in Same-Day Discharge Outcomes?

Background: Different approaches for total hip arthroplasty (THA) may offer advantages in regard to achieving same-day-discharge (SDD) success.

Methods: We retrospectively identified patients aged ≥ 18 years who underwent elective primary THA from 2015 to 2020 who were formally enrolled in a single institution's SDD program. A total of 1,127 and 207 patients underwent THA via direct anterior approach and posterior approach, respectively, were included.

Impact of a Digital Balancing Tool on Femur and Tibial First Total Knee Arthroplasty: A Prospective Nonrandomized Controlled Trial.

Background: Recent developments in intra-operative sensor technology provide surgeons with predictive and real-time feedback on joint balance. It remains unknown, however, whether these technologies are better suited to femur-first or tibia-first workflows. This study investigates the balance accuracy, precision and early patient outcomes between the femur-first and tibial-first workflows using a digital gap-balancing tool.

What are the major drivers of outcomes in cervical deformity surgery?

Background Context: Cervical deformity (CD) correction is becoming more challenging and complex. Understanding the factors that drive optimal outcomes has been understudied in CD corrective surgery.

Purpose: The purpose of the study was to weight baseline (BL) factors on impact upon outcomes following CD surgery.

What are the major drivers of outcomes in cervical deformity surgery?

Background Context: Cervical deformity (CD) correction is becoming more challenging and complex. Understanding the factors that drive optimal outcomes has been understudied in CD correction surgery.

Purpose: The purpose of this study is to assess the factors associated with improved outcomes (IO) following CD surgery.

Documented and Undocumented Psychiatric Conditions Affect the Length of Stay and Discharge Disposition Following Total Hip Arthroplasty.

Background: Despite increased efforts toward patient optimization, some patients have undocumented conditions that can affect costs and quality metrics for institutions and physicians. This study evaluates the effect of documented and undocumented psychiatric conditions on length of stay (LOS) and discharge disposition following total hip arthroplasty (THA).

Methods: A retrospective review of all primary THAs from 2015 to 2020 at a high-volume academic orthopedic specialty hospital was conducted.

Preoperative optimization for vascular involvement complicating revision total hip arthroplasty.

Unlabelled: Vascular complications in revision total hip arthroplasty may occur in cases where the components of the hip implant migrate through the acetabular wall, through the iliopectineal line of the pelvis, and into the pelvic cavity. This migration may lead to substantial intrapelvic vascular compromise, drastically increasing the surgical complexity and potential risk for morbidity and mortality in these surgical cases. Here, we present a case of a 78-year-old woman with significant acetabular protrusio, which resulted in intraoperative compromise of the external iliac artery with rapid extravasation.
