Total knee arthroplasty in the outpatient vs inpatient settings: impact of site of care on early postoperative economic and clinical outcomes.

Background: The incidence of total knee arthroplasty (TKA) surgery performed in the outpatient setting has increased as a result of improved perioperative recovery protocols, bundled payments, and challenges brought by the coronavirus disease of 2019 (COVID-19) pandemic on health systems. This study evaluates early postoperative clinical and economic outcomes of patients treated in the inpatient vs outpatient setting using the Attune Knee System (AKS).

Methods: Patients with an elective, primary TKA implanted with the AKS, from Q4 2015 to Q1 2021, were identified within the Premier Healthcare Database.

Real-world 2-year clinical and economic outcomes among patients receiving a medial collared, triple tapered primary hip system versus other implants for total hip arthroplasty.

Objective: To evaluate real-world outcomes of patients receiving ACTIS, a medial collared, triple-tapered (MCTT) hip system vs. other implants, for primary total hip arthroplasty (THA).

Methods: Patients with THA between 2016-2021 from Mercy Healthcare Systems-Orthopedics Database were evaluated.

Treatment patterns and clinical and economic burden of hip dislocation following primary total hip arthroplasty in England.

Aims: The aim of this study was to estimate the clinical and economic burden of dislocation following primary total hip arthroplasty (THA) in England.

Methods: This retrospective evaluation used data from the UK Clinical Practice Research Datalink database. Patients were eligible if they underwent a primary THA (index date) and had medical records available 90 days pre-index and 180 days post-index.

The assessment of muscle fatigue in orthopedic surgeons, by comparing manual versus automated broaching in simulated total hip arthroplasty.

Total hip arthroplasty procedures are physically demanding for surgeons. Repetitive mallet swings to impact a surgical handle (impactions), can lead to muscle fatigue, discomfort, and injuries. The use of an automated surgical hammer may reduce fatigue and increase surgical efficiency.

Standard table direct anterior approach within an early discharge protocol for cementless total hip arthroplasty: experience from a Japanese hospital.

Aims: Clinical and economic outcomes associated with an early discharge protocol for cementless total hip arthroplasty (THA) via a direct anterior approach (DAA) on a standard table without a dedicated traction table) were assessed. These outcomes were compared against a benchmark of THA care approximated from a national database.

Materials And Methods: This retrospective, observational, comparative cohort study evaluated 250 patients receiving THA with a standard table DAA approach under an early discharge protocol at a medical center in Japan between 2016 and 2017 (intervention).

Healthcare resource utilization and costs for hip dislocation following primary total hip arthroplasty in the medicare population.

Aim: To estimate 2-year healthcare resource utilization (HCRU) and costs of dislocation following primary total hip arthroplasty (THA).

Materials And Methods: This retrospective evaluation used medical claims from the US Medicare database. Patients were eligible if they were ≥65 years old, underwent a primary elective inpatient THA between 1 January 2010 and 31 December 2016 (index), and had continuous Medicare coverage and enrollment ≥365 days prior to index (baseline).

Survival analysis for all-cause revision following primary total hip arthroplasty with a medial collared, triple-tapered primary hip stem versus other implants in real-world settings.

Objective: Patients that undergo total hip replacement (THA) are at risk of revision surgery. This study evaluated the cumulative incidence of revision following a medial collared, triple tapered (MCTT) primary hip stem versus other implants in real-world settings using electronic medical records.

Methods: This was a retrospective cohort study that used the Mercy Healthcare Systems - Orthopedics Database (MHSOD) to identify ACTIS total hip system, a MCTT primary hip stem for THA, and any other primary THA between 2016 and 2020.

Medical resource utilization and costs for intraoperative and early postoperative periprosthetic hip fractures following total hip arthroplasty in the medicare population: A retrospective cohort study.

This study assessed the impact of intraoperative and early postoperative periprosthetic hip fractures (PPHFx) after primary total hip arthroplasty (THA) on health care resource utilization and costs in the Medicare population.This retrospective observational cohort study used health care claims from the United States Centers for Medicare and Medicaid Standard Analytic File (100%) sample. Patients aged 65+ with primary THA between 2010 and 2016 were identified and divided into 3 groups - patients with intraoperative PPHFx, patients with postoperative PPHFx within 90 days of THA, and patients without PPHFx.
