Unlabelled: Despite substantial advances in primary TKA, numerous studies using historic TKA implants suggest only 82% to 89% of primary TKA patients are satisfied. We reexamined this issue to determine if contemporary TKA implants might be associated with improved patient satisfaction. We performed a cross-sectional study of patient satisfaction after 1703 primary TKAs performed in the province of Ontario. Our data confirmed that approximately one in five (19%) primary TKA patients were not satisfied with the outcome. Satisfaction with pain relief varied from 72-86% and with function from 70-84% for specific activities of daily living. The strongest predictors of patient dissatisfaction after primary TKA were expectations not met (10.7x greater risk), a low 1-year WOMAC (2.5x greater risk), preoperative pain at rest (2.4x greater risk) and a postoperative complication requiring hospital readmission (1.9x greater risk).

ASA Class Is a Stronger Predictor of Early Revision Risk Following Primary Total Knee Arthroplasty than BMI.
JB JS Open Access
January 2025
School of Medicine, Rural Clinical School, University of Queensland, Toowoomba, Queensland, Australia.
Background: Although there is a known correlation between obesity and revision risk following total knee arthroplasty (TKA), there is an ongoing debate regarding the appropriateness of denying TKA solely based on the body mass index (BMI) of a patient. Our aim was to determine whether a patient's American Society of Anesthesiologists (ASA) class predicts their risks of early all-cause revision and revision for periprosthetic joint infection (PJI) following primary TKA, independent of their BMI.
Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) were obtained regarding all patients who underwent primary TKA for osteoarthritis in Australia from January 1, 2015, to December 31, 2022.
Hemostatic effect of oxidized regenerated cellulose vs. topical tranexamic acid in total knee arthroplasty-a prospective randomized controlled trial.
Front Surg

Department of Knee Joint Surgery, Xi'an Honghui Hospital, Xi'an Jiaotong University, Xi'an, Shaanxi, China.
Aims: This study compared the hemostatic effects and complications of oxidized regenerated cellulose (ORC) and topical TXA in total knee arthroplasty (TKA), thus providing a reference for the use of ORC as an alternative hemostatic agent to TXA in TKA.
Methods: A total of 105 patients were included in this study and randomized into blank control, ORC, and TXA groups. The primary outcomes were total blood loss, hemoglobin drop (Hb drop), transfusion rates, and incidence of thrombosis.
In functionally aligned total knee arthroplasty, femoral component rotation follows the transepicondylar axis to achieve flexion balance.
Knee Surg Sports Traumatol Arthrosc
January 2025
Clinical Research Department, Sydney Knee Specialists, Kogarah, New South Wales, Australia.
Purpose: In functionally aligned (FA) total knee arthroplasty (TKA), femoral component rotation (FCR) is personalised to optimise flexion gap balance. As axial malalignment has been attributed to patellofemoral complications, this study assessed FA FCR in relation to the surgical transepicondylar axis (TEA) and early implant survivorship.
Methods: We analysed 446 robotic-assisted primary TKAs in 393 patients using FA with preresection gap balancing.
Effect of Antiseptic Irrigation Solutions on Primary Human Knee Fibroblasts Cultured in Human Platelet Lysate.

Department of Orthopedic Surgery, Mayo Clinic, 200 First Street S.W., Rochester, MN, 55905.
Background: Native and periprosthetic joint infections are devastating conditions fraught with patient morbidity and mortality. Aseptic and septic joints are often debrided and irrigated to decrease bacterial loads when preventing or treating infection. However, the effect of clinically used irrigation solutions on the native cellular components of the synovial joint is unknown.

Translational Medical Center, National Center of Neurology and Psychiatry, Tokyo, Japan.
Background: The efficacy and safety of avalglucosidase alfa for Pompe disease (PD) have been demonstrated in a global Phase 3 trial (COMET) in patients with late-onset PD (LOPD) and a global Phase 2 trial (Mini-COMET) in patients with infantile-onset PD (IOPD). This case series examines the individual results of three Japanese patients enrolled in these trials.
Methods: Case reports were assembled from data collected in the COMET and Mini-COMET trials.
