Stemmed femoral knee prostheses: effects of prosthetic design and fixation on bone loss.

Although the revision rates for modern knee prostheses have decreased drastically, the total number of revisions a year is increasing because many more primary knee replacements are being done. At the time of revision, bone loss is common, which compromises prosthetic stability. To improve stability, intramedullary stems are often used. The aim of this study was to estimate the effects of a ste...

Prosthetic fixation in cementless total knee arthoplasty. Influence of techniques, prosthetic design and bone graft enhacement

The knowledge of the biological and mechanical factors which have an influnce in non cemented knee prosthesis' survival and the complexity of the biomechanical (kinematic) demands to which are summitted the different non cemented prosthesis, show the importance of a "natural" solution specially in the field of the substitition of the interposition fibrocartilague structures, such as the meniscu...

Design and Evaluation of a Magnetorheological Damper Based Prosthetic Knee

In this work, a magnetorheological (MR) damper based above-knee prosthesis is design and evaluated based on its performance in swing phase and in stance phase. Initially, a dynamic system model for swing phase of a prosthetic leg incorporating a single-axis knee with ideal MR damper was built. The dynamic properties of the damper are represented with Bingham parametric model. From Bingham model...

Progressive femoral cortical and cancellous bone density loss after uncemented tapered-design stem fixation

BACKGROUND Aseptic implant loosening and periprosthetic bone loss are major problems after total hip arthroplasty (THA). We present an in vivo method of computed tomography (CT) assisted osteodensitometry after THA that differentiates between cortical and cancellous bone density (BD) and area around the femoral component. METHOD Cortical and cancellous periprosthetic femoral BD (mg CaHA/mL), ...
