Area Deprivation Index as a proxy for socioeconomic status in outpatient orthopaedic surgery patients - A prospective registry cross sectional study.

Background: We aimed to determine if Area Deprivation Index (ADI) is associated with self-reported metrics socioeconomic status (SES), and to assess the relationship between ADI and preoperative score on common patient reported outcome scores (PROS).

Methods: Patients presenting for outpatient orthopaedic surgery completed Patient-Reported Outcome Metric Information System (PROMIS) and joint-specific PROS. ADI was determined from geocoded home address.

Three-dimensional-based native alignment phenotype classification system: Description for use in planning for deformities during total knee arthroplasty.

Introduction: Total knee arthroplasty (TKA) is a complex surgical procedure that traditionally relies on two-dimensional radiographs for pre-operative planning. These radiographs may not capture the intricate details of individual knee anatomy, potentially limiting the precision of surgical interventions. With advancements in imaging technology, there is an opportunity to refine TKA outcomes.

The Impact of Preoperative Weight Loss Timing on Surgical Outcomes in Total Hip Arthroplasty.

Background: Elevated body mass index (BMI) increases surgical complications post-total hip arthroplasty (THA). However, the effects of rapid weight loss pre-THA remain unclear. This study evaluated patients who had initial BMIs between 40 and 50, and then achieved a BMI under 35 at various intervals before their THA.

The use of preoperative continuous positive airway pressure in patients with obstructive sleep apnea following total hip arthroplasty: A propensity score matched analysis.

Introduction: Obstructive sleep apnea (OSA) impacts approximately 936 million individuals globally and is known to complicate post-surgical recovery, particularly after total hip arthroplasty (THA). While continuous positive airway pressure (CPAP) is commonly recommended for managing OSA, its effect on THA recovery remains uncertain. The study aimed to assess the impact of CPAP use on post-THA outcomes in patients with OSA, focusing on medical complications and periprosthetic joint infection (PJI) at 90 days and 1 year.

Timing Matters: Optimizing the Timeframe for Preoperative Weight Loss to Mitigate Postoperative Infection Risks in Total Knee Arthroplasty.

Background: We explore the incidence of periprosthetic infections post-total knee arthroplasty (TKA) in morbidly obese patients who achieved weight loss. Current American Academy of Orthopaedic Surgeons guidelines suggest a preoperative body mass index (BMI) below 40 for TKA. This study assesses infection risks in patients initially who had a BMI of 40-50 who reduced their BMI to under 35 at varying intervals prior to surgery.

Mako® Robotic-Arm Assisted Total Hip Arthroplasty: Avoiding Impingement with Updated THA Software.

The use of robotic-assisted total hip arthroplasty and three-dimensional computed tomography scan-based templating has become increasingly popular over the last 10 years. However, proper planning and execution are vital to producing optimal patient outcomes. In order to achieve these outcomes, the robotic-assisted system requires training, familiarity, and experience.

True Cost of Operating Room Time: Implications for an Orthopaedic Trauma Service.

Objective: To derive an accurate estimate of the operating cost per minute for an orthopaedic trauma room.

Study Design: Retrospective economic analysis.

Setting: Level II Trauma Center.
