MECHANISTIC STUDY OF CRACK INITIATION AND PROPAGATION IN CROSSLINKED ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENES (UHMWPE) SUBJECTED TO STATIC AND CYCLIC LOADING
Many total joint replacement (TJR) designs incorporate a hard bearing material articulating against a soft bearing (polymeric) material. The bearing polymer, typically made of ultra high molecular weight polyethylene (UHMWPE) has been successfully used for the last four decades. However, these …

Probabilistic Musculoskeletal Simulation Methods to Address Intersegmental Dependencies of the Knee, Hip, and Spine
… impactful on the outcomes of patients with total joint replacement, where pathology and compensatory strategies develop during multi-joint interactions. Additionally, probabilistic methods are well suited to address knee, hip, and spine regional interdependence by using input distributions …

DEVELOPMENT OF ENHANCED CALIBRATION SYSTEM AND MEASUREMENT PROGRAM FOR RADIOSTEREOMETRIC ANALYSIS
… standard used to evaluate the performance of Total Joint Replacement. However, the assessment of novel surgical procedures is limited by the present accuracy and precision of RSA. At the same time, complications in the measurement of RSA radiographs confine its large-scale clinical …

The application of the homogenisation method to the numerical modelling of cancellous bone
… behaviour using the homogenisation method. In total joint replacement, cancellous bone (the soft porous bone which lies below the articular surfaces at weight-bearing joints) provides the medium for the transfer of loads from the artificial component, or prosthesis to the hard, outer cortical …

Leukaniveltä affisioivien sairauksien hoito – kirurgiakeskeinen näkökulma
… G. Mercurin toimittama kirja Temporomandibular Joint Total Joint Replacement – TMJ TJR sekä Gary Warburtonin johtaman kirurgitiimin kuvaama leikkausvideo. Kirjallisuuskatsauksen pyrkimyksenä oli kartoittaa yleisesti leukanivelen sairauksia, niiden diagnosointia sekä erilaisia hoitomuotoja. …

Tribological and mechanical characterizations of polyelectrolyte multilayer nanoassemblies
… presence of bovine calf serum, used to simulate joint synovial fluid. In the latter case, a significant decrease in wear rates, in tests using a clinically relevant number of cycles and articulation pattern, pointed to the efficacy of PEM-coated systems for wear reduction in total joint …

Ex-Vivo Injection of Biomaterial Biologics for Treatment of Osteonecrosis
… chronic inflammation, poor bone regeneration, joint deformity, osteoarthritis, and potentially a total joint replacement. One potential treatment is to remove necrotic tissue via minimally invasive saline washes followed by local injection of biomaterials, which can act as drug- or …

The Need, Value and Affordability of First-line Treatments for Hip and Knee Osteoarthritis in Alberta
… treatments are underused globally. In Alberta, joint replacements are publicly funded. Meanwhile, first-line treatments are funded with private insurance or out-of-pocket which reduces access. We sought to inform the policy-making process in Alberta by addressing three objectives: 1) Describe …

Osteoarthritis. Epidemiologic and genetic aspects.
… association between body mass index (BMI) and total hip replacement (THR) and total knee replacement (TKR) due to osteoarthritis (OA), (II) assess the association between the mechanical load of work and THR and TKR due to OA, (III) evaluate the natural history of radiographic hip OA with …

Impact loading and functional tissue engineering of articular cartilage
… functional neo-cartilage for diseased tissue replacement. Experiments demonstrate that cartilage subjected to a single, non-surface disrupting 1.1 J (Low) impact experiences sufficient degeneration over 4 weeks to become functionally equivalent to tissue subjected to a single, surface …

Transitional Care Coach Program Evaluation at a Southwest Urban Medical Center
… statistical analysis (e.g. adding categories of Total Joint Replacement and Sepsis diagnoses), (3) tracking of number of days to readmittance to allow for improvement to be measured and analyzed beyond a single dichotomous category. Evidence-based recommendations have been made to continue and …

Characterization and computational modelling of acrylic bone cement polymerisation
Total joint replacement is one of the most successful surgical procedures and is a proven treatment for arthritis. Despite low failure rates, the wide application of the treatment means that large numbers of prostheses fail and must be revised. Improved pre-clinical testing methods for these …

Histological characterization of CT-identified osteoarthritic subchondral cysts and co-registration of CT with MRI
… (OA) is a chronic disease that affects the joints, most commonly hands, hips, knees, feet, and spine (Litwic et al. 2013). The disease becomes more common with advanced age and is one of the most prevalent causes of disability in older populations. Currently there is no cure besides total …

Impact of the DNA methyltransferase inhibitor, 5-azacytidine, on chondrocytic phenotype
… the synovial lining and adjacent bone of joints. OA currently affects over 30% of the US population. This figure is almost certain to increase as the American population ages and the childhood obesity “epidemic” impacts the consequent development of affected individuals. OA is also an …

Co-Developing Culturally Responsive Pre-Surgical Education for First Nation and Métis Hip and Knee Replacement Care in Saskatchewan
… in Saskatchewan accessing pre-surgical care for total joint replacements (TJR) and to co-develop a culturally responsive pre-surgical education program in partnership with a patient advisory committee (PAC). Methods: An exploratory qualitative approach was used across two phases of research. In …

Validation of numerical prediction of bone ingrowth into cementless implants
Total joint replacement was pioneered by John Charnley in the late 1950's, and has since revolutionised the management of arthritis sufferers. By 1991, an estimated 5 million people had undergone hip replacements. Although relatively successful, the cemented components had some problems, and this …

Novel Approach for Non-Invasive Prediction of Body Shape and Habitus
… close to the underlying bone. Obesity influences joint loads and motion patterns, and BMI may not be sufficient to capture the distribution of a subject’s weight or to differentiate differences between subjects. Subjects in need of a joint replacement are more likely to have mobility issues or …
