Routine use of antibiotic-laden bone cement in total knee arthroplasty is a cost-effective practice in the single-payer healthcare system.

Purpose: The purpose of this study was to determine the cost-effectiveness of antibiotic-laden bone cement (ALBC) in primary total knee arthroplasty (TKA) from the perspective of a single-payer healthcare system.

Methods: A cost-utility analysis (CUA) was performed over a 2-year time horizon comparing primary TKA with either ALBC or regular bone cement (RBC) from the perspective of the single-payer Canadian healthcare system. All costs were in 2020 Canadian dollars.

A sub-Kelvin cryogen-free EPR system.

We present an EPR instrument built for operation at Q band below 1K. Our cryogen-free Dewar integrates with a commercial electro-magnet and bridge. A description of the cryogenic and RF systems is given, along with the adaptations to the standard EPR experiment for operation at sub-Kelvin temperatures.

A high-performance wave guide cryogenic thermal break.

We describe a high-performance wave guide cryogenic thermal break. This has been constructed both for Ka band, using WR28 wave guide, and Q band, using WR22 wave guide. The mechanical structure consists of a hexapod (Stewart platform) made from pultruded carbon fibre tubing.

Creation and Validation of the Self-esteem/Self-image Female Sexuality (SESIFS) Questionnaire.

Introduction: Self-esteem and self-image are psychological aspects that affect sexual function.

Aims: To validate a new measurement tool that correlates the concepts of self-esteem, self-image, and sexuality.

Methods: A 20-question test (the self-esteem/self-image female sexuality [SESIFS] questionnaire) was created and tested on 208 women.

Continuous infusion of bupivacaine following total knee arthroplasty: a randomized control trial pilot study.

An RCT pilot-study was conducted to assess efficacy of a 48-h continuous local infiltration of intra-articular bupivacaine (0.5% at 2 cc/h) versus placebo (0.5% saline at 2 cc/h) in decreasing PCA morphine consumption following TKA.
