https://medicalxpress.com/orthopedics-news/ en-us Latest medical news and research in Orthopaedics 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 New findings from a trial conducted at Children's Hospital Colorado (Children's Colorado) and University of Colorado (CU) Anschutz School of Medicine demonstrate significantly increased growth rates in children with achondroplasia, the most common form of dwarfism. These results highlight Children's Colorado's leadership in pediatric orthopedic research and commitment to advancing therapies for rare skeletal conditions. The study is published in the New England Journal of Medicine. https://medicalxpress.com/news/2026-06-growth-outcomes-children-dwarfism.html Tue, 30 Jun 2026 16:20:03 EDT news702053530 A biodegradable pressure sensor could help people with knee injuries exercise and heal faster, University of Connecticut researchers report in Science Advances. The knee can take a great deal of abuse, thanks to the cartilage that cushions it. But if it's not moved and exercised enough, the knee stiffens and has poor blood flow. The cartilage can degrade or tear, worsening any injury already there. So people with injured knees have to move in order to heal. The challenge is knowing how much exercise or movement is too much. https://medicalxpress.com/news/2026-06-wireless-biodegradable-sensor-knees-dangerous.html Mon, 29 Jun 2026 16:00:06 EDT news701965381 The largest and longest clinical trial of its kind has found that resurfacing the kneecap during total knee replacement is likely to be the most cost-effective approach for patients and health care systems over the long term. Researchers from the University of Oxford and the University of Aberdeen followed more than 1,700 patients for 20 years as part of the KAT (Knee Arthroplasty Trial) study, making it the longest randomized controlled trial ever conducted in knee orthopedics. https://medicalxpress.com/news/2026-06-kneecap-resurfacing-patients-health.html Wed, 17 Jun 2026 18:30:05 EDT news700906032 Embolization of abnormal blood vessels using rapidly resorbable gelatin-based microspheres is safe and provides significant, lasting pain relief and functional improvement for patients with osteoarthritis-related knee pain, according to a new study published in Radiology. https://medicalxpress.com/news/2026-06-nonsurgical-procedure-relief-knee-pain.html Tue, 16 Jun 2026 10:00:03 EDT news700735021 Orthopedic implants are designed to restore movement and relieve pain, offering patients a second or even third chance at mobility. A hip or knee replacement is often framed as a durable fix, engineered to last for years, sometimes decades, inside the human body. And modern hip and knee implants exceed expectations, providing long service time and significantly improved quality of life for the vast majority of patients. But durability inside biology, especially the human body, is never static once a foreign material is introduced. It responds continuously, at every scale. https://medicalxpress.com/news/2026-06-joints-corrosion-reshape-hip-knee.html Mon, 15 Jun 2026 17:10:03 EDT news700759501 For patients suffering from traumatic injuries that leave behind "volumetric" gaps—where significant bone and blood vessels are lost—the clock is always ticking. Without a nearby blood supply, cells in the center of a large injury cannot survive, often leading to permanent tissue loss or failed grafts. https://medicalxpress.com/news/2026-06-natural-protein-scaffold-bone-blood.html Thu, 11 Jun 2026 16:40:04 EDT news700413241 An international research team has identified dozens of new genetic risk factors linked to lumbar spinal stenosis, a common degenerative condition of the lower spine. The study, led by researchers at the University of Oulu, provides new insight into the biological mechanisms behind one of the most frequent causes of mobility problems in older adults. The work was published in the journal Nature Communications. https://medicalxpress.com/news/2026-06-nerve-pain-genetic-clues-reshape.html Tue, 09 Jun 2026 19:00:01 EDT news700243022 For millions of people living with osteoarthritis, daily life can involve a frustrating cycle of pain and stiffness. While current treatments like over-the-counter medications or steroid injections can temporarily dull the ache, they do not stop the joint from deteriorating. A Yale study published in the journal Bioactive Materials found that the medication lacosamide acts as a highly effective, dual-purpose treatment that relieves joint pain and reverses cartilage damage in osteoarthritis, especially when a specialized hydrogel delivers the drug directly into the joint. https://medicalxpress.com/news/2026-06-hydrogel-relieves-osteoarthritis-pain-cartilage.html Wed, 03 Jun 2026 12:40:02 EDT news699706023 As professional baseball sees another high-profile elbow injury with Toronto Blue Jays right-hander José Berríos having undergone ulnar collateral ligament (UCL) surgery, new research from the University of Waterloo suggests many pitchers may be able to reduce stress on their elbows without sacrificing velocity. https://medicalxpress.com/news/2026-05-smarter-softer-baseball-pitchers-elbows.html Wed, 27 May 2026 13:20:01 EDT news699100141
