https://medicalxpress.com/orthopedics-news/ en-us Latest medical news and research in Orthopaedics Robotic assistance is increasingly used in knee replacement surgery worldwide: in 6% of procedures in the UK, compared with 16% in the U.S. and 42% in Australia. The aim is to help surgeons place knee replacements more precisely and tailor surgery to a patient's anatomy. https://medicalxpress.com/news/2026-08-robotic-knee-patient-outcomes-surgeon.html Fri, 21 Aug 2026 13:00:05 EDT news706533961 Biomedical scientists have developed a new nanoscale imaging technique that allows researchers to directly see how bone-forming cells use nutrients and build bone inside the body. https://medicalxpress.com/news/2026-08-imaging-technique-reveals-bone-microscopic.html Fri, 21 Aug 2026 11:40:02 EDT news706525861 When it comes to daily aches and pains, it's not uncommon for knees to be a main source. And while there can be many different long-term causes of such issues, osteoarthritis is often a reason why. https://medicalxpress.com/news/2026-08-osteoarthritis.html Tue, 18 Aug 2026 23:00:02 EDT news706258113 Osteoarthritis is a leading cause of chronic pain and disability worldwide. Current intra-articular standards of care, such as analgesics, corticosteroids and viscosupplements, provide only transient symptomatic relief and do not reliably modify disease progression. A major translational barrier is the rapid clearance of small-molecule drugs and biologics from synovial fluid, as well as the difficulty of delivering hydrophobic compounds at therapeutic concentrations without systemic exposure. https://medicalxpress.com/news/2026-08-hydrogel-prolongs-joint-retention-osteoarthritis.html Thu, 13 Aug 2026 07:30:01 EDT news705814313 Osteoarthritis (OA) is a chronic, painful joint disease and a leading cause of disability. Despite its prevalence, therapies for osteoarthritis are limited and focus on symptom management. Now, researchers are combining genetic studies of Utah families with AI-based molecular biology tools to find new medications that may ultimately help treat OA at its source. https://medicalxpress.com/news/2026-08-osteoarthritis-medicines-ai-genetics.html Thu, 06 Aug 2026 15:00:05 EDT news705159841 In January this year, a team of Johns Hopkins Medicine investigators, led by pathologist Aaron W. James, MD, Ph.D., discovered that sensory neurons in skeletal tissue are constantly sensing their environment and quickly respond to injuries. In new research published in Science Translational Medicine, they describe how this response profoundly affects growth plates, the soft cartilage at the end of bones in children that support normal growth and development, and how they respond to targeted treatment in mice. https://medicalxpress.com/news/2026-08-sensory-nerves-growth-plate-injuries.html Wed, 05 Aug 2026 14:00:20 EDT news705068461 Researchers at the Department of Women's and Children's Health have used a novel technique to map which genes are active in different regions of the skeleton's growth plates. The findings offer new clues about how the body controls bone elongation—and why certain genetic mutations lead to skeletal disorders. The study is published in the journal Bone Research. https://medicalxpress.com/news/2026-08-spatial-growth-plate-tissue-bones.html Wed, 05 Aug 2026 13:00:06 EDT news705148621 Teeth and bones are among the hardest structures in the human body, but certain inherited conditions can rob them of that strength. One of them is hypophosphatasia (HPP), a rare, lifelong genetic bone disorder that disrupts the development of bones and teeth, leaving them unusually soft and fragile. A recent study set out to determine how common HPP is across Central and Eastern Europe and how it presents in patients. https://medicalxpress.com/news/2026-08-rare-bone-disease-untreated-patients.html Mon, 03 Aug 2026 15:20:03 EDT news704969011 A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania. The findings offer new clues for treating muscular dystrophy and provide new insights into the mechanisms of cancer. https://medicalxpress.com/news/2026-07-chromosome-protein-muscle-rarity-cancers.html Fri, 31 Jul 2026 14:00:02 EDT news704641562 Seoul National University (SNU) College of Engineering announced that a research team led by Nathaniel S. Hwang, a professor in the Department of Chemical and Biological Engineering, has developed a bioceramic fracture fixation material that promotes bone regeneration by precisely controlling the timing of magnesium ion (Mg²⁺) release to suppress inflammatory immune responses during osteoporotic fracture healing. https://medicalxpress.com/news/2026-07-bioceramic-coated-implant-osteoporotic-fracture.html Wed, 29 Jul 2026 16:00:02 EDT news704554681 Exercise finds improvements in pain and function may fall short of what patients would notice in daily life, but more studies are needed to make firm conclusions, a new publication in Cochrane Database of Systematic Reviews finds. https://medicalxpress.com/news/2026-07-hip-arthritis-pain-function-gains.html Wed, 22 Jul 2026 20:00:04 EDT news703915093 Joint replacements are among the most common surgeries worldwide, and preventing blood clots is critical to recovery. A Dalhousie-led study published this month—one of the most robust of its kind to date—found that a straightforward treatment following surgery may be just as effective as a more complex one, challenging common assumptions in post-surgical care. The results could simplify care and reduce costs across health systems. https://medicalxpress.com/news/2026-07-aspirin-costlier-blood-thinners-hip.html Mon, 20 Jul 2026 14:00:02 EDT news703773541 In a global breakthrough published in Nature Genetics, researchers have successfully mapped the cells and genes that regulate bone formation and loss at an unprecedented scale and discovered the critical role that blood vessel cells play in bone health. https://medicalxpress.com/news/2026-07-genetic-bone-diseases.html Fri, 10 Jul 2026 09:00:01 EDT news702889621 A new type of hip replacement implant reduces the risk of joint dislocation after surgery by 70%, according to a new study involving 1,600 patients across 44 hospitals in Sweden and the UK, published in The Lancet. The new implant consists of a small ball encased in a much larger plastic ball, which provides better stability. https://medicalxpress.com/news/2026-07-dual-mobility-hip-implant-dislocation.html Thu, 02 Jul 2026 18:30:02 EDT news702224461
