https://medicalxpress.com/orthopedics-news/ en-us Latest medical news and research in Orthopaedics Researchers found that a diet high in ultra-processed foods is associated with higher amounts of fat stored inside thigh muscles, regardless of calorie or fat intake, physical activity or sociodemographic factors in a population at risk for knee osteoarthritis. Results of the study were published in Radiology. Higher amounts of intramuscular fat in the thigh could potentially increase the risk for knee osteoarthritis. https://medicalxpress.com/news/2026-04-people-consume-ultra-foods-worse.html Tue, 14 Apr 2026 10:00:01 EDT news695293502 Scientists at the Buck Institute for Research on Aging, along with collaborators at UC San Francisco, have discovered that APOE4, the most common genetic risk factor for Alzheimer's disease, causes bone quality deficits specifically in female mice, through a mechanism that is invisible to standard imaging and can emerge as early as midlife. The findings, published in Advanced Science, reveal an unexpected biological link between Alzheimer's risk and skeletal health, and identify a new molecular pathway that could one day inform earlier diagnosis of cognitive decline or guide treatment for bone quality loss in women who carry the APOE4 gene. https://medicalxpress.com/news/2026-04-apoe4-alzheimer-gene-silently-undermines.html Mon, 13 Apr 2026 18:20:02 EDT news695318042 A research team including scientists and engineers from University of Colorado Boulder, CU Anschutz and Colorado State University has developed a suite of new therapies that prompt aging or damaged joints to repair themselves within weeks, according to animal studies. https://medicalxpress.com/news/2026-04-simple-shot-reverse-osteoarthritis-weeks.html Sun, 12 Apr 2026 14:30:07 EDT news694772759 Good news: Scientists may be closer to a new way to treat arthritis. https://medicalxpress.com/news/2026-04-scientists-ways-regrow-joints-arthritis.html Tue, 07 Apr 2026 16:00:01 EDT news694783635 If you have a knee replacement, imagine pointing your phone at your knee and pulling up an app that tells you how much stress the artificial joint is experiencing. Knowing the activities that cause the biggest problems—which can lead to a second replacement surgery—would be invaluable. Research led by Binghamton University is closer to making this technology a reality. https://medicalxpress.com/news/2026-04-closer-smart-sensors-knee.html Fri, 03 Apr 2026 10:40:03 EDT news694430642 A research team from the Department of Orthopedics and Traumatology, School of Clinical Medicine, LKS Faculty of Medicine at the University of Hong Kong (HKUMed), has developed a titanium implant surface that can be activated by near-infrared (NIR). With just 15 minutes of NIR irradiation, this surface can eliminate 99.94% of Staphylococcus aureus (S. aureus) biofilms without the use of antibiotics, while simultaneously promoting bone-implant fusion. https://medicalxpress.com/news/2026-04-smart-titanium-implant-enables-rapid.html Wed, 01 Apr 2026 13:00:01 EDT news694264081 Postmenopausal women face a high risk of bone fractures. Due to declines in estrogen levels, which can lead to an increased risk of osteoporosis, even a low-impact fall can result in a serious hip, back, or wrist injury. An estimated one in three women over 50 will experience a fracture due to bone loss in their lifetime. A new study in The Lancet Regional Health - Americas from researchers at Tulane University has found that heart health may affect fracture risk after menopause, with women at a higher risk of cardiovascular disease more likely to experience hip and other major bone fractures. https://medicalxpress.com/news/2026-03-heart-health-metric-fracture-postmenopausal.html Fri, 27 Mar 2026 19:30:02 EDT news693827633 Nearly one in 10 people who are implanted with a surgical fix to their spine will develop a serious bacterial infection, despite prophylactic antibiotic treatment. In a recent study published in the journal PLOS One, researchers at Thomas Jefferson University have engineered a device they hope will help prevent this devastating complication. https://medicalxpress.com/news/2026-03-antibiotic-reservoir-surgical-infections.html Thu, 26 Mar 2026 18:30:01 EDT news693764941 Osteoarthritis, a condition that causes pain and reduced mobility in joints such as the knees and fingers, is one of the most common joint disorders worldwide, particularly among aging populations. The disease is characterized by the gradual breakdown of cartilage, which normally cushions the bones within joints. https://medicalxpress.com/news/2026-03-key-protein-cartilage-osteoarthritis-treatment.html Fri, 20 Mar 2026 10:40:01 EDT news693221162 A research team from the Department of Pharmacology and Pharmacy, LKS Faculty of Medicine of the University of Hong Kong (HKUMed), has found that nitrogen-containing bisphosphonates (NBPs), a medication widely used in the treatment of osteoporosis, may significantly reduce the risk of Alzheimer's disease and related dementias (ADRD) in older adults with osteoporosis or fragility fractures. This drug repurposing approach offers a promising avenue for the prevention of ADRD, potentially alleviating the global burden of these conditions. The research findings are published in Alzheimer's & Dementia. https://medicalxpress.com/news/2026-03-osteoporosis-drugs-dementia.html Tue, 17 Mar 2026 19:40:01 EDT news692965220 Finding an effective treatment for osteosarcoma, the most common type of bone cancer in children and young adults, has puzzled medical researchers for 40 years. Now, a new study by researchers at Case Western Reserve University and University Hospitals shows some promising results. The study, published in BMC Medicine, found that a specially engineered immune-cell treatment, called OSM CAR-T, successfully attacks osteosarcoma tumors in mouse models. https://medicalxpress.com/news/2026-03-therapy-common-bone-cancer-children.html Tue, 17 Mar 2026 15:40:12 EDT news692979062 Heat generated by alternating magnetic fields (AMF) helps common antibiotics work better against prosthetic joint infections, researchers at UT Southwestern Medical Center found. The study, published in Scientific Reports, advances previous research at UT Southwestern that demonstrated the efficacy of AMF in eradicating biofilm from the surface of prosthetic joints such as those used in knee and hip replacement surgeries. https://medicalxpress.com/news/2026-03-boosts-antibiotics-effectiveness-prosthetic-infections.html Fri, 13 Mar 2026 12:00:03 EDT news692618821 A bone-like composite developed at EPFL uses naturally occurring enzymes to accelerate mineralization through an energy-efficient, room-temperature process.
