Sex-based differences in risk of revision for infection after hip, knee, shoulder, and ankle arthroplasty in osteoarthritis patients: a multinational registry study of 4,800,000 implants.

Background And Purpose:  We aimed to determine sex differences for periprosthetic joint infections after primary arthroplasty of the hip, knee, ankle, and shoulder in osteoarthritis patients in an international perspective.

Methods:  This is a multinational combined arthroplasty registry study. Each arthroplasty registry performed Cox-regression analysis of their data and reported the crude and adjusted hazard ratios (HR) with an a priori designed data form.

Can blood flow restriction therapy improve quality of life and function in dissatisfied knee arthroplasty patients?

Aims: Approximately 10% to 20% of knee arthroplasty patients are not satisfied with the result, while a clear indication for revision surgery might not be present. Therapeutic options for these patients, who often lack adequate quadriceps strength, are limited. Therefore, the primary aim of this study was to evaluate the clinical effect of a novel rehabilitation protocol that combines low-load resistance training (LL-RT) with blood flow restriction (BFR).

Total knee arthroplasty: The need for better patient selection.

Total knee arthroplasty (TKA) is a widely performed surgical intervention designed to relieve pain and restore function in patients with severe knee joint degeneration, most commonly due to osteoarthritis. This procedure involves replacing the damaged knee joint with a prosthetic implant, providing significant improvements in mobility and quality of life. While TKA is beneficial for many, the individuals who stand to gain the most are those with advanced knee arthritis unresponsive to conservative treatments, typically aged 60 and above, experiencing activity-related pain and functional limitations.

Vascular occlusion for optimising the functional improvement in patients with knee osteoarthritis: a randomised controlled trial.

Objectives: Knee osteoarthritis (KOA) is a leading cause of global disability with conventional exercise yielding only modest improvements. Here we aimed to investigate the benefits of integrating blood flow restriction (BFR) into traditional exercise programmes to enhance treatment outcomes.

Methods: The Vascular Occlusion for optimizing the Functional Improvement in patients with Knee Osteoarthritis randomised controlled trial enrolled 120 patients with KOA at Ghent University Hospital, randomly assigning them to either a traditional exercise programme or a BFR-enhanced programme over 24 sessions in 12 weeks.
