Replacement with implants that contain only non-allergenic components can provide relief for this group of patients. https://medicalxpress.com/news/2021-06-non-allergenic-joints-relief.html Fri, 04 Jun 2021 08:41:48 EDT news542014906 Knee osteoarthritis (OA) is a global health problem. Almost half the adults over the age of 75 have some form of knee OA—one of the leading causes of disability worldwide. Because there is no cure for knee OA, current treatment relies on accurately identifying and staging the disease. https://medicalxpress.com/news/2021-05-ai-bone-knee-osteoarthritis.html Tue, 11 May 2021 12:57:46 EDT news539956664 Scientists have developed a computer method that may help improve understanding and treatment of Crohn's disease, which causes inflammation of the digestive tract. https://medicalxpress.com/news/2019-09-ai-method-boost-crohn-disease.html Mon, 30 Sep 2019 06:58:41 EDT news489045515 French pharmaceutical firm Sanofi said Tuesday it is partnering with Google to use artificial intelligence and deep analytics tools to sift through its data to find better treatments. https://medicalxpress.com/news/2019-06-sanofi-google-treatments.html Tue, 18 Jun 2019 04:57:14 EDT news480052627 (HealthDay)—An artifical intelligence system based on deep learning is feasible for detecting full-thickness anterior cruciate ligament (ACL) tears within the knee joint on magnetic resonance (MR) images, according to a study published online May 8 in Radiology: Artificial Intelligence. https://medicalxpress.com/news/2019-06-ai-based-deep-acl-knee.html Tue, 04 Jun 2019 13:10:01 EDT news478871795 U.S. health officials on Tuesday proposed steps to improve the government's system for overseeing medical devices, which has been criticized for years for failing to catch problems with risky implants and medical instruments. https://medicalxpress.com/news/2018-04-ideas-boosting-medical-device-safety.html Tue, 17 Apr 2018 11:02:44 EDT news443181756 Different surface topographies and materials provide interesting ways to study cell behaviour and potentially provide novel solutions for treating joint defects.

After a few years, many hip and knee joints have to be replaced. Much more complex are intervertebral disc implants, which cannot easily be replaced after their "expiry date" and which up to now have had to be reinforced in most cases. This restricts the patient's freedom of movement considerably. Researchers at Empa have now succeeded in coating mobile intervertebral disc implants so that they show no wear and will now last for a lifetime. https://medicalxpress.com/news/2014-05-technology-durable-spinal-disc-implants.html Thu, 29 May 2014 10:56:04 EDT news320579754 Recent advances in robotics technology make it possible to create prosthetics that can duplicate the natural movement of human legs. This capability promises to dramatically improve the mobility of lower-limb amputees, allowing them to negotiate stairs and slopes and uneven ground, significantly reducing their risk of falling as well as reducing stress on the rest of their bodies. https://medicalxpress.com/news/2013-11-robotic-advances-artificial-legs-emulate.html Fri, 08 Nov 2013 09:09:16 EST news303124141 (Medical Xpress)—A team from the University of Texas at Arlington has used mathematical modeling to develop a computer simulation they hope will one day improve the treatment of dangerous reactions to medical implants such as stents, catheters and artificial joints. https://medicalxpress.com/news/2013-09-successfully-implant-device-reactions.html Tue, 24 Sep 2013 07:01:50 EDT news299224901 A computer tomograph (CT) with special software solutions is helping to improve the planning of radiotherapy, thus making cancer treatment more effective. Radiotherapy aims to irradiate tumors as precisely as possible. To make this possible, radiotherapists first make CT images to determine the exact size and location of the area to be irradiated. However, image quality is impaired by metal implants and breathing movements, thus making therapy planning more difficult. To counter these problems, the Siemens tomograph SOMATOM Definition AS Open RT Pro edition is equipped with software that offsets the effects of such interference so that the radiation can be more precisely targeted. The device has been equipped with a number of special features to enhance it for use in radiotherapy. https://medicalxpress.com/news/2013-09-special-ct-radiotherapy.html Thu, 19 Sep 2013 08:00:01 EDT news298794908 French surgeons have fitted 650 people with replacement hips that had not been certified as meeting European standards, it emerged Thursday in a case with echoes of a scandal over faulty breast implants. https://medicalxpress.com/news/2013-05-unauthorised-hips-french-patients.html Thu, 02 May 2013 11:55:44 EDT news286714538 Stems cells taken from just a few grams of body fat are a promising weapon against the crippling effects of osteoarthritis. https://medicalxpress.com/news/2013-04-stem-cells-arthritis.html Sun, 28 Apr 2013 18:50:01 EDT news286392514 A Case Western Reserve University chemistry professor has begun imbedding magnetic nanoparticles in the toughest of plastics to understand why more than 40,000 Americans must replace their knee and hip replacements annually. https://medicalxpress.com/news/2013-02-effort-hips-knees-bad.html Mon, 04 Feb 2013 15:52:14 EST news279215497 Inpatient hospital treatment accounts for the largest proportion of health care spending in the U.S., with the use of diagnostic imaging services such as MRIs, frequently implicated as the probable cause.  A new analysis finds that the biggest expense may not be imaging technology but from supplies including medical devices, such as stents and artificial joints. "One of the take-away messages for hospitals is that they should examine their own data in closer detail to explore the costs that are rapidly rising and have a better understanding for the underlying reasons," said lead author Jared Lane Maeda, Ph.D., of Truven Health Analytics in Washington, D.C. https://medicalxpress.com/news/2012-08-inpatient-linked-medical-devices.html Wed, 29 Aug 2012 09:00:01 EDT news265447154 Hip replacement is one of the most frequent operations carried out in Germany. Each year, doctors implant some 200,000 artificial hip joints. Often the artificial hips need to be replaced just ten years later. In the future, a new implant currently being developed using high technology materials could help prevent premature revision surgeries. https://medicalxpress.com/news/2012-05-hip-implant-long-term.html Fri, 04 May 2012 14:00:01 EDT news255356920 The culprit behind a failed hip or knee replacements might be found in the mouth.
