Mobile or fixed bearing for total knee arthroplasty? Ambulatory gait analysis results

Background: Mobile-bearing knee replacements have some theoretical advantages over fixed-bearing devices. However, very few randomized controlled clinical trials have been published to date, and studies showed little clinical and subjective advantages for the mobile-bearing using traditional systems of scoring. The choice of the ideal outcome measure to assess total joint replacement remains a complex issue. However, gait analysis provides objective and quantifying evidences of treatment evaluation. Significant methodological advances are currently made in gait analysis laboratories and ambulatory gait devices are now available. The goal of this study was to provide gait parameters as a new objective method to assess total knee arthroplasty outcome between patients with fixed- and mobile-bearing, using an ambulatory device with minimal sensor configuration. This randomized controlled double-blind study included to date 14 patients: the gait signatures of four patients with mobile-bearing were compared to the gait signatures of nine patients with fixed-bearing pre-operatively and post-operatively at 6 weeks, 3 months and 6 months. Each participant was asked to perform two walking trials of 30m long at his/her preferred speed and to complete a EQ-5D questionnaire, a WOMAC and Knee Society Score (KSS). Lower limbs rotations were measured by four miniature angular rate sensors mounted respectively, on each shank and thigh. A new method for a portable system for gait analysis has been developed with very encouraging results regarding the objective outcome of total knee arthroplasty using mobile- and fixed-bearings.

Définir le risque du carcinome spinocellulaire: rôle de la clinique et du rapport anatomopathologique [Risk of cutaneous squamous cell carcinomas: the role of clinical and pathological reports].

The history of most cutaneous squamous cell carcinomas (CSCC) is limited to the skin. However, about 4% of these malignancies are at risk of metastasis and can be life-threatening. This risk is determined by clinical and histological elements which are individually recognized, but so far staging systems allow us neither to assess a risk score, nor to adopt a standardized therapeutical approach. This article reviews prognostic factors for CSCC, and underlines the need for the clinician to have all clinical and histological elements available, in order to try to define the best therapeutical strategy for each case, following up-to-date recommendations.
