Metal-on-metal hip resurfacing arthroplasty provides excellent long-term survivorship and function in patients with a good-sized femoral head : results of a single, non-designer surgeon's cohort.

Aims: To establish the survivorship, function, and metal ion levels in an unselected series of metal-on-metal hip resurfacing arthroplasties (HRAs) performed by a non-designer surgeon.

Methods: We reviewed 105 consecutive HRAs in 83 patients, performed by a single surgeon, at a mean follow-up of 14.9 years (9.

The Medial Rotation Knee replacement: Clinical and radiological results of a multi-centre surveillance study at five years.

Background: The Medial Rotation Knee (MRK) has one of the lowest revision rates of total knee replacement designs in the National Joint Registry. While survival is one metric of performance of implants, patient-reported outcomes, combined with clinical and radiological evaluation, allow more complete analysis. We report the five-year results of a prospective, multi-centre surveillance study of the MRK.

Obsessive-compulsive symptoms and attentional bias: An eye-tracking methodology.

Background And Objectives: Cognitive models suggest that attentional biases are integral in the maintenance of obsessive-compulsive symptoms (OCS). Such biases have been established experimentally in anxiety disorders; however, the evidence is unclear in Obsessive Compulsive disorder (OCD). In the present study, an eye-tracking methodology was employed to explore attentional biases in relation to OCS.

Evaluation of the posterior tibial slope on MR images in different population groups using the tibial proximal anatomical axis.

We measured the posterior tibial slope for the medial and lateral tibial plateau separately in MR images of 143 knees (71 women, 72 men) and compared the measurements between genders and different ethnic groups. For the whole population the mean medial slope was 5.7 degrees and the mean lateral slope 5.

Intensive physiotherapy for vegetative and minimally conscious state patients: a retrospective audit and analysis of therapy intervention.

Purpose: To analyse physiotherapy interventions and evaluate their effectiveness in the prevention and management of contracture with patients admitted in either vegetative or minimally conscious state in a UK Inpatient Regional Acquired Brain Injury Rehabilitation Service.

Method: Retrospective audit of dependency levels and physiotherapy interventions in ten vegetative or minimally conscious state patients admitted over a 3-year period (2006-2009). Admission and discharge patient dependency status, Wessex Head Injury Matrix data and passive range of movement measurements on admission and discharge from physiotherapy were recorded.

Design considerations and life prediction of metal-on-metal bearings: the effect of clearance.

Background: Clinical observations suggest that metal-on-metal arthroplasties that have been implanted for more than twenty years do fail. It is proposed that there are not two, but three distinct phases of wear life for any metal-on-metal implant system: bedding-in, steady state, and end point. In this study, we asked two questions: can we explain late failure due to wear, and will there be a late failure mechanism due to a change in the frictional torque?

Methods: In order to characterize wear failure, an analysis was made of five retrieved metal-on-metal couples that were mapped with use of a roundness machine.

Use of prepolymerized cement spacers to augment the femoral component in revision total knee arthroplasty: a clinical outcome report and laboratory experiment.

A technique for revision total knee arthroplasty managing posterior femoral condylar bone loss with prepolymerized polymethyl methacrylate cement spacers as augments to the femoral component is described in 10 consecutive cases. The maximum follow-up time is 63 months. This method allows for maintenance of the posterior joint line, which in turn facilitates appropriate flexion-extension gap balancing.
