Trends and epidemiology in robotic-assisted total knee arthroplasty: Reduced complications and shorter hospital stays.

Introduction: This study provides an in-depth analysis of the immediate postoperative outcomes and implications or robotic-assisted total knee arthroplasty (RA-TKA) compared with conventional TKA (C-TKA), particularly with regard to mortality, complications, hospital stay and costs, drawing from a comprehensive nationwide data set.

Methods: The Nationwide Inpatient Sample (NIS) database, the largest all-payer inpatient healthcare database in the United States, was used to identify all patients who underwent RA-TKA or C-TKA from 2016 to 2019. A total of 527,376 cases, representing 2,638,679 patients who underwent elective TKA were identified, of which 88,415 had RA-TKA.

Comparative evaluation of postoperative outcomes and expenditure between robotic and conventional single-level lumbar fusion surgery: a comprehensive analysis of nationwide inpatient sample data.

Introduction: In this study, we investigate the evolution of lumbar fusion surgery with robotic assistance, specifically focusing on the impact of robotic technology on pedicle screw placement and fixation. Utilizing data from the Nationwide Inpatient Sample (NIS) covering 2016 to 2019, we conduct a comprehensive analysis of postoperative outcomes and costs for single-level lumbar fusion surgery. Traditionally, freehand techniques for pedicle screw placement posed risks, leading to the development of robotic-assisted techniques with advantages such as reduced misplacement, increased precision, smaller incisions, and decreased surgeon fatigue.

SARS-CoV-2 seroconversion in children attending daycare versus adults in Germany between October 2020 and June 2021.

Background: Data on seroconversion rates after SARS-CoV-2 infection in young children (<6 years) is scarce. The present study compares seroconversion rates between young children and adults and identifies associated factors.

Methods: The COALA study ("Corona-outbreak-related examinations in daycare centers") investigated transmission dynamics of SARS-CoV-2 in daycare centers and associated households (10/2020-06/2021).

Mortality, Survival, and Readmissions During a 12-Month Follow-Up After Hip Fracture: Inpatient Rehabilitation Versus Home Rehabilitation.

Purpose: This study compared readmissions, survival, and mortality during a 12-month follow-up period of inpatient rehabilitation and home rehabilitation for older persons who had experienced a hip fracture.

Methods: This work was retrospective cohort research. Between January 1 and December 30, 2019, the medical records of 280 elderly patients who were admitted to a hospital with a hip fracture were analyzed.
