Joints Achy? Don't Blame Mother Nature

Posted 7 days ago by Drugs.com

TUESDAY, Jan. 10, 2017 – You might want to think twice the next time you're ready to blame the weather for your aches and pains, researchers say. Some people swear that changes in humidity, temperature, air pressure and the like trigger back pain and arthritis. But a team at the George Institute for Global Health in Newtown, Australia said it found no evidence to support that theory. "The belief that pain and inclement weather are linked dates back to Roman times. But our research suggests this belief may be based on the fact that people recall events that confirm their pre-existing views," said Chris Maher, director of the institute's musculoskeletal division. The study included nearly 1,350 Australians with either lower back pain or osteoarthritis of the knee. The study participants' pain flare-ups were compared with weather data. There was no association between back pain/knee ... Read more

Is Running Bad Or Good for Your Knees?

Posted 12 days ago by Drugs.com

THURSDAY, Jan. 5, 2017 – Everybody believes running can leave you sore and swollen, right? Well, a new study suggests running might actually reduce inflammation in joints. "It flies in the face of intuition," said study co-author Matt Seeley, an associate professor of exercise sciences at Brigham Young University in Provo, Utah. "This idea that long-distance running is bad for your knees might be a myth." Seeley and his colleagues reached their surprising conclusion after analyzing the knee joint fluid of several healthy men and women between the ages of 18 and 35. The researchers looked for signs of inflammation in chemical markers before and after a 30-minute run and found little difference. "What we now know is that for young, healthy individuals, exercise creates an anti-inflammatory environment that may be beneficial in terms of long-term joint health," lead author Robert Hyldahl ...

Knee Cartilage Product Approved to Repair Defects

Posted 14 Dec 2016 by Drugs.com

WEDNESDAY, Dec. 14, 2016 – Maci (autologous cultured chondrocytes) has been approved by the U.S. Food and Drug Administration to repair defective cartilage of the knee. The treatment, derived from healthy cartilage from the patient's own knee, uses tissue engineering to grow cells that replace the damaged cartilage, the agency said in a news release. Cartilage defects commonly stem from an injury, knee strain, overuse, muscle weakness or general wear-and-tear, the FDA said. The new process uses the patient's own (autologous) cells, which are placed on a collagen membrane scaffolding that is surgically implanted over the area where damaged cartilage was removed. The membrane is designed to be absorbed by the body over time. The surgeon installing the implants should be trained in the Maci product. Multiple implants can be used if there is more than one defect, the FDA said. Maci's ... Read more

Cartilage From Nose Used to Repair Damaged Knees

Posted 21 Oct 2016 by Drugs.com

THURSDAY, Oct. 20, 2016 – Using cells from the cartilage in patients' noses, Swiss doctors have successfully made patches to treat 10 adults whose knee cartilage was damaged by injury. Two years after the transplants, most of the patients grew new cartilage in their knees and reported improvements in pain, knee function and quality of life. "We have developed a new, promising approach to the treatment of articular cartilage injuries," said lead researcher Ivan Martin, a professor of tissue engineering at the University of Basel. The articular cartilage is the tissue that covers and protects the ends of the knee bones, and injuries to it can lead to degenerative joint conditions like osteoarthritis. Although the results of this preliminary trial are encouraging, more research is needed before this technique could become widely available, Martin stressed. "Before this can be offered to ...

Number of Americans With Severe Joint Pain Keeps Rising

Posted 6 Oct 2016 by Drugs.com

THURSDAY, Oct. 6, 2016 – Severe joint pain plagues an increasing number of aging, often arthritic Americans, a new report finds. In 2002, about 10.5 million people in the United States said they battled severe joint pain, but by 2014 that number had jumped to 14.6 million, said researchers from the U.S. Centers for Disease Control and Prevention. The CDC team defined "severe" joint pain as discomfort measuring 7 or more on a 1-to-10 score on a questionnaire, with 1 being no pain and 10 being "pain and aching as bad as it can be." The problem may only get worse, the researchers said, since much of this joint pain is linked to arthritis. One in every four people with arthritis in the new study rated his or her pain as "severe," and arthritis cases among Americans are expected to rise. In the United States, "arthritis affected an estimated 52.5 million [22.7 percent] adults in 2010-2012 ... Read more

Encouraging Surgical ICU Patients to Get Moving Pays Off

Posted 2 Oct 2016 by Drugs.com

FRIDAY, Sept. 30, 2016 – Getting out of bed and moving around as soon as possible benefits surgical intensive care unit patients, a new study shows. Among 200 surgical ICU patients in the United States, Germany and Austria, those encouraged to move around sooner than usual were discharged from the ICU and the hospital earlier than others, researchers found. "We have become much more successful in making sure patients hospitalized after serious injury or major surgery survive their stays in surgical ICUs," said study leader Dr. Matthias Eikermann, of Massachusetts General Hospital in Boston. "But many patients who spend a long time in the ICU develop muscle weakness that can lead to prolonged rehabilitation requirements, with some being unable to walk or take care of themselves up to a year after hospital discharge," he said in a hospital news release.

Nanoparticles Ease Aching Joints in Mice

Posted 27 Sep 2016 by Drugs.com

TUESDAY, Sept. 27, 2016 – New research in mice suggests that tiny nanoparticles might one day be a better way to deliver medicine to inflamed joints in humans. The therapy may reduce the risk of osteoarthritis in people who have suffered joint injuries, the study authors said. About 12 percent of osteoarthritis cases stem from previous joint injuries. The experimental treatment may also benefit people who already have osteoarthritis, according to the study team from Washington University School of Medicine in St. Louis. While nonprescription painkillers – such as acetaminophen (Tylenol) and ibuprofen (Advil, Motrin) – help reduce the pain of joint injuries, they don't stop cartilage destruction caused by inflammation. "I see a lot of patients with osteoarthritis, and there's really no treatment," study senior author Dr. Christine Pham, an associate professor of medicine, said in a ... Read more

Knee Surgery Rarer, but Problems More Likely, for Minority Patients

Posted 18 Aug 2016 by Drugs.com

THURSDAY, Aug. 18, 2016 – Minority patients in the United States are less likely to get knee replacement surgery, but more likely to have complications when they do, a new study finds. Knee replacement can be used to treat patients who have severe pain, stiffness and reduced knee function, often due to arthritis or injury. More than 600,000 knee replacements are done in the United States each year. "Even after adjusting for certain patient demographics, socioeconomic status, and health care system characteristics, significant racial disparities in [total knee replacement] utilization and outcomes exist," corresponding study author Yan Ma said. Ma is an associate professor of epidemiology and biostatistics at the Milken Institute School of Public Health at George Washington University in Washington, D.C. Ma and his colleagues analyzed federal data on more than 547,000 total knee ... Read more

Will 'Unloading' Shoes Help Your Arthritic Knees?

Posted 12 Aug 2016 by Drugs.com

FRIDAY, Aug. 12, 2016 – For reducing pain from arthritic knees, "unloading" shoes don't offer a leg up over conventional walking shoes, new research indicates. With their modified midsoles, unloading shoes aim to reduce the force (or "load") placed on an affected knee joint, according to their manufacturer. But after focusing on one brand – the "Gel Melbourne OA" shoe by Asics – the Australian researchers concluded the special shoes were no better for knee arthritis than standard lace-up footwear. "With its specific design features, [the unloading shoe] does significantly reduce the forces acting across the inner compartment of the knee joint," said study lead author Rana Hinman. But its users didn't report greater pain relief than those wearing new regular walking shoes, said Hinman, an associate professor of physiotherapy at the University of Melbourne. Among study participants, ... Read more

Common Surgeries Raise Risk for Opioid Dependence: Study

Posted 12 Jul 2016 by Drugs.com

MONDAY, July 11, 2016 – After knee surgery and other common operations, patients have an elevated risk of growing dependent on opioid painkillers, a new study finds. These prescription painkillers include hydrocodone (Vycodin, Lortab), oxycodone (OxyContin) and fentanyl, the narcotic implicated in the April 21 death of rock legend Prince. "For a lot of surgeries there is a higher chance of getting hooked on painkillers," said study author Dr. Eric Sun, an instructor at Stanford University School of Medicine, in Palo Alto, Calif. But Sun cautioned that the finding isn't a reason to avoid surgery. "The message isn't that you shouldn't have surgery," said Sun. "Rather, there are things that anesthesiologists can do to reduce the risk by finding other ways of controlling the pain and using replacements for opioids when possible." For the study, the researchers examined medical claims of ... Read more

Repaired ACL More Likely to Tear Again in Young Women

Posted 9 Jul 2016 by Drugs.com

THURSDAY, July 7, 2016 – Female athletes younger than 25 have the highest risk for a repeat tear of the knee's anterior cruciate ligament (ACL) after surgery to repair it, a new study says. The study included just over 500 male and female athletes who underwent ACL reconstruction with a hamstring graft and were followed for two years. Their average age was 27. They were allowed to return to sports six to 12 months after surgery if they were pain-free, had equal quadriceps/hamstring strength, and had finished a rehabilitation program. "Our research noted that female patients under the age of 25 with a [smaller] graft size of less than 8 millimeters have an increased chance of re-tearing their ACL following reconstruction," study lead author Dr. Duong Nguyen said in an American Orthopaedic Society of Sports Medicine news release. He is an orthopedic surgeon and adjunct clinical professor ... Read more

Health Tip: Exercising After Joint Replacement

Posted 28 Jun 2016 by Drugs.com

-- Having joint replacement surgery doesn't mean exercise is out of the picture. The American Academy of Orthopaedic Surgeons offers these guidelines: Your doctor may have restrictions on your exercise regimen, so always consult your doctor before you exercise after surgery. Until your doctor says it's OK, don't jog, ski, run or do other exercises that put the replaced joint under stress. Opt for less-stressful exercises such as swimming, doubles tennis, golf and biking.
