The clinical and radiographic results of 174 female and 86 male Innex (Zimmer, Warsaw, Indiana) mobile bearing total knee arthroplasty systems (245 patients) were evaluated, with particular emphasis on gender-related differences at five-year follow-up. Pre-operative Knee Society (KS) function and total scores were lower in women than in men. All KS scores showed a significant improvement at follow-up, but women still obtained lower KS function scores than men. Self-reported function was significantly better for male knees. No gender differences were observed for component alignment, while the occurrence of radiolucent lines, endosteal cavitations, and wear was significantly greater in male knees. Male Innex mobile bearing knees exhibited better clinical function and satisfaction than their female peers at five-year follow-up, despite inferior radiographic findings and higher revision rates.

Access to robot-assisted total knee arthroplasty varies significantly by race/ethnicity.

Background: Racial/ethnic disparities in access to total knee arthroplasty (TKA) have been extensively demonstrated. Over the past several years, there has been a rapid increase in the utilization of robot-assisted TKA (RA-TKA). Therefore, this study sought to determine whether previously established racial/ethnic disparities extend to access to RA-TKA relative to conventional TKA.

Background: In order to increase the stability of tibial component in total knee arthroplasty (TKA), intramedullary stem extensions (SE) have been developed. The aim of this systematic review and meta-analysis is to address the critical knowledge gap on post-operative outcomes and complications rate comparison between tibial component with SE compared to the tibial component standard configuration (SC) in primary cemented TKA.
Methods: We conducted a comprehensive search of online databases, including Pubmed, Embase, ISI Web of science, Cochrane Library, and Scopus, using the following MeSH terms, (total knee arthroplasty) OR (TKA) OR (total knee replacement) AND (Tibial stem) OR (stem extension) OR (long stem).

Introduction: the two most used types of prosthesis are posterior cruciate ligament preserving (CR) and posterostabilized (PS). Proponents of CR TKA cited greater stability, greater range of motion, better proprioception, and greater kickback associated with the native posterior cruciate ligament.
Objective: to assess the degree of pain, return of mobility and functionality of the joint of patients who had TKA, between the years January 2018 and December 2022 at the Juárez Centro Medical Surgical Unit, using their records as a study unit.
Modifications to the Geriatric Nutritional Risk Index Predicts Complications after Total Joint Arthroplasty.

Background: Preoperative malnutrition is a known risk factor for postoperative complications following total joint arthroplasty (TJA), however, there is scant literature comparing which nutritional index is best at predicting these outcomes. The purpose of this study was to investigate the utility of the Maastricht Index (MI), Onodera's Prognostic Index (OPNI), the Geriatric Nutritional Risk Index (GNRI), and a novel, modified Geriatric Nutritional Risk Index (mGNRI) in predicting periprosthetic joint infection (PJI), wound complications (WC), readmission, and reoperation rates after TJA.
Methods: A single-center, retrospective cohort study was performed of patients who underwent primary TJA from January 2016 to December 2021.
Contemporary Cementless Patellar Implant Survivorship: A Systematic Review and Meta-Analysis of 3005 Patellae.
J Knee Surg

Orthopaedic Surgery, Mayo Clinic, Rochester, United States.
Introduction: Historically, cementless patellar implants were fraught with issues of fixation and polyethylene wear. However, contemporary cementless patellar implants incorporate modern technologies for implant design and offer the potential for improved biological fixation and longevity. As such, an evaluation of the performance of modern cementless patellae is needed.
