The goal of this study was to evaluate the outcome at a mean follow-up of 24.5 years (range, 22-26 years) of a consecutive series of 138 patients (145 hips) treated with total hip arthroplasty (THA) with the use of the Taperloc femoral component (Biomet, Warsaw, Indiana). This was an FDA-approved prospective study. All surgeries were performed by a single surgeon. Each of the 138 patients (145 hips) was followed annually until death, femoral component revision, or a minimum of 22 years. Complete clinical and radiographic follow-up was obtained on 95% of living patients at 5 years, and 100% at 10, 15, 20, and 24.5 years. Of the original series of 145 hips, only 1 femoral component (0.7%) had undergone revision for aseptic loosening, and 1 was loose by radiographic criteria (0.7%). Femoral osteolysis was identified in 8 hips (5.5%). A subset of 63 THAs in 56 patients was followed for a mean of 24.5 years. In this group, no femoral component required revision for aseptic loosening, and 1 was loose by radiographic criteria. Femoral osteolysis was present in 4 hips. Survivorship analysis of the femoral component with revision for aseptic loosening as the endpoint was 99% (95% confidence interval, 0.97-100) at 26 years. This stem demonstrates excellent fixation at a follow-up of 24.5 years with no apparent deterioration of the results with time.

Medium chained triglycerides (MCT) ketogenic diet is being extensively investigated for its neuroprotective effects against adverse effects associated with aging and neurodegenerative disorders. Aging is a common risk factor for the development of both osteoporosis and neurological disorders. Hence, suppression of aging and age-related neurodegeneration might contribute to delaying skeletal aging.

Background: Total hip arthroplasty is the preferred treatment for advanced hip osteoarthritis, yet complications like hip dislocation (0.2 %-10 %) persist due to factors such as implant design, positioning, surgical technique, and patient-specific conditions. Impingement between prosthetic components or the acetabulum and proximal femur is a primary cause of instability.

The prototype of a biomimetic multi-spiked connecting scaffold (MSC-Scaffold) represents an essential innovation in the fixation in subchondral trabecular bone of components for a new generation of entirely cementless hip resurfacing arthroplasty (RA) endoprostheses. In designing such a functional biomaterial scaffold, identifying the microstructural and mechanical properties of the host bone compromised by degenerative disease is crucial for proper post-operative functioning and long-term maintenance of the endoprosthesis components. This study aimed to explore, depending on the occurrence of obesity, changes in the microstructure and mechanical properties of the subchondral trabecular bone in femoral heads of osteoarthritis (OA) patients caused by the MSC-Scaffold embedding.

Cancer cachexia is a debilitating syndrome characterized by progressive weight loss, muscle wasting, and systemic inflammation. Despite the prevalence and severe consequences of cancer cachexia, effective treatments for this syndrome remain elusive. Therefore, there is a greater need for well-characterized animal models to identify novel therapeutic targets.

Background: Unicompartmental knee arthroplasty (UKA) procedures have become much more common in the United States in recent years, with >40,000 UKAs performed annually. However, it is estimated that 10% to 40% of UKAs fail and thus require conversion to total knee arthroplasty (TKA). In the field of total joint arthroplasty, robotic-assisted surgeries have demonstrated advantages such as better accuracy and precision of implant positioning and improved restoration of a neutral mechanical axis.
