Bipolar vs. monopolar sealer in decreasing blood loss and transfusion rate in patients undergoing two-stage exchange in infected total knee arthroplasty: propensity score-matched study.

Background: Two-stage revision in infected total knee arthroplasty increases the risk of blood loss and the need for transfusion. The present study aimed to test the hemostatic efficacy of a bipolar sealer to reduce blood loss and transfusion requirements after the first stage in patients affected by peri-prosthetic knee infections.

Methods: Twenty-four patients undergoing 2-stage arthroplasty for infected TKA using a bipolar sealer (Haemodiss, Kylix, Naples, IT) were compared with 24 patients of a historical control group in which conventional electrocautery was used.

Stability of the surface diffusion flow and volume-preserving mean curvature flow in the flat torus.

We prove that, in the flat torus and in any dimension, the volume-preserving mean curvature flow and the surface diffusion flow, starting -close to a strictly stable critical set of the perimeter ,  exist for all times and converge to a translate of exponentially fast as time goes to infinity.

Can a 1.5-Stage Revision Be an Effective Alternative for Chronic Periprosthetic Hip and Knee Infections? A Systematic Review and Meta-Analysis.

Background: A 1.5-stage revision could be an alternative to a 2-stage revision for treating hip and knee chronic periprosthetic infections, guaranteeing the maintenance of joint function and infection control and preventing infection-free patients from undergoing further surgery. Our systematic review aimed to answer several questions about the indication, the infection eradication rate, and the long-term functional outcome of 1.
