“…According to Duda et al [16,22], this does not correspond to Stress shielding in total hip prosthesesthe physiological facts. Thus, the whole femur has been studied in the present study, as has been done in other works [16,23,24]. In this way, definite statements about the load situation in the distal part can be made.…”

“…For example, they modelled the screws of the cerviotrochanteric component as pins. Such simplifications were made in the study by Taylor et al [24] as well, wherein the authors numerically computed the bone remodelling stimulus in the periprosthetic bone that was provided with the thrust plate prosthesis. This stimulus represents the difference between the load situations in the intact and the periprosthetic femora.…”

Aseptic loosening of the prosthesis is still a problem in artificial joint implants. The loosening can be caused by, among other factors, resorption of the bone surrounding the prosthesis owing to stress shielding. In order to find out the influence of the prosthesis type on post-operative stress shielding, a static finite element analysis of a femur provided with the conventional uncemented stem BICONTACT and of one with the femoral neck prosthesis SPIRON was carried out. Strain energy densities and maximal principal strain distributions were calculated and compared with the physiological situation. Here, stress shielding was demonstrated in both periprosthetic femora. To determine the areas of the stress shielding, the bone in each FE model was subdivided into three regions of interest (ROI): proximal, diaphyseal, and distal. The numerical computations show stress shielding in the proximal ROI of both periprosthetic femora. Diaphyseally, the femoral neck prosthesis SPIRON, in contrast to the conventional uncemented long-stem prosthesis BICONTACT, causes no decrease in the strain distribution and thus no stress shielding. Distally, no change in the load distribution of either periprosthetic femur could be found, compared with the physiological situation.

“…Bone adaptation and remodelling: Bone remodelling simulations have been performed extensively, primarily to assess stress shielding around the femoral component of hip arthroplasty (Perez et al, 2010;Taylor et al, 2004;Weinans et al, 1994;Gupta et al, 2006;Huiskes et al, 1992;Weinans et al, 1992Weinans et al, , 1993Stulpner et al, 1997;Folgado et al, 2009;Pal and Gupta 2011;Shim et al, 2012). Since the publication of the first bone remodelling simulations around implants by Huiskes and co-workers (Huiskes, 1988), there have only been incremental developments, for example accounting for overload induced bone loss (Behrens et al, 2009;Scannell and Prendergast, 2009).…”

a b s t r a c tFinite element has been used for more than four decades to study and evaluate the mechanical behaviour total joint replacements. In Huiskes seminal paper "Failed innovation in total hip replacement: diagnosis and proposals for a cure", finite element modelling was one of the potential cures to avoid poorly performing designs reaching the market place. The size and sophistication of models has increased significantly since that paper and a range of techniques are available from predicting the initial mechanical environment through to advanced adaptive simulations including bone adaptation, tissue differentiation, damage accumulation and wear. However, are we any closer to FE becoming an effective screening tool for new devices? This review contains a critical analysis of currently available finite element modelling techniques including (i) development of the basic model, the application of appropriate material properties, loading and boundary conditions, (ii) describing the initial mechanical environment of the bone-implant system, (iii) capturing the time dependent behaviour in adaptive simulations, (iv) the design and implementation of computer based experiments and (v) determining suitable performance metrics.The development of the underlying tools and techniques appears to have plateaued and further advances appear to be limited either by a lack of data to populate the models or the need to better understand the fundamentals of the mechanical and biological processes. There has been progress in the design of computer based experiments. Historically, FE has been used in a similar way to in vitro tests, by running only a limited set of analyses, typically of a single bone segment or joint under idealised conditions. The power of finite element is the ability to run multiple simulations and explore the performance of a device under a variety of conditions. There has been increasing usage of design of experiments, probabilistic techniques and more recently population based modelling to account for patient and surgical variability. In order to have effective screening methods, we need to continue to develop these approaches to examine the behaviour and performance of total joint replacements and benchmark them for devices with known clinical performance.Finite element will increasingly be used in the design, development and pre-clinical testing of total joint replacements. However, simulations must include holistic, closely corroborated, multi-domain analyses which account for real world variability.

In vivo telemetric determination of shear and axial loads on a regenerative cartilage scaffold following ligament disruption

Recent interest in repair of chondral and osteochondral cartilage defects to prevent osteoarthritis caused by ligament disruption has led to the research and development of biomimetic scaffolds combined with cell-based regeneration techniques. Current clinical focal defect repair strategies have had limited success. New scaffold-based approaches may provide solutions that can repair extensive damage and prevent osteoarthritis. This study utilized a novel scaffold design that accommodated strain gauges for shear and axial load monitoring in the canine stifle joint through implantable telemetry technology. Loading changes induced by ligament disruption are widely implicated in the development of injury-related osteoarthritis. Seeding the scaffold end with progenitor cells resulted in higher shear stress than without cell seeding and histology showed significantly more bone and cartilage formation. Biomechanically, the effect of transecting the anterior cruciate ligament was a significant reduction in braking load in shear, but no change axially, and conversely a significant reduction in push-off load axially, but no change in shear. This is the first study to report shear loads measured directly in knee joint tissue. Further, advances of these measurement techniques are critical to developing improved regeneration strategies and personalizing reliable rehabilitation protocols.
