Women More Sensitive to Metal Joint Implants Than Men: Study

Posted 1 day 7 hours ago by Drugs.com

WEDNESDAY, April 26, 2017 – One reason women are more likely than men to have complications after hip or knee replacement surgery may be because they're more sensitive to the metals in joint implants, a new study suggests. Researchers reviewed the cases of more than 2,600 patients who were evaluated for unexplained pain after total hip and/or knee replacement. All had metal implants. None had signs of infection, inflammation or other conditions that would explain their pain. Sixty percent of the patients were women. They had higher average pain scores than men – 6.8 vs. 6.1 on a scale of 0-10, according to the study. Blood tests showed signs of immune sensitization to implant metals in 49 percent of the women and 38 percent of the men. The gender difference remained even after researchers used a stricter definition of sensitization – 25 percent versus 18 percent. "These findings may ... Read more

Smoking May Raise Risk of Complications After Joint Surgery

Posted 5 Apr 2017 by Drugs.com

WEDNESDAY, April 5, 2017 – Hip or knee replacement patients who smoke are at increased risk for infections requiring repeat surgery, researchers report. They analyzed data from more than 15,000 patients who underwent either total hip or knee replacements between 2000 and 2014. The investigators found that the overall risk of repeat surgery for infections within 90 days was only 0.71 percent. However, the risk was 1.2 percent for current smokers, compared with 0.56 percent for nonsmokers. After adjusting for other factors, the researchers concluded that current smokers' risk was 80 percent higher than nonsmokers and former smokers. The researchers also found that for both current and former smokers, the risk of 90-day hospital readmission not involving surgery rose with the number of "pack-years" smoked – a calculation of the number of packs smoked per day over a number of years. ...

Knee Replacement Doesn't Always Pay, Researchers Say

Posted 29 Mar 2017 by Drugs.com

TUESDAY, March 28, 2017 – Knee replacement surgery isn't always a game changer, according to a new study that raises questions about the increasingly common procedure. The patients who benefit most have severe osteoarthritis. But for people with milder symptoms, the expense might not be justified, researchers determined. "This study suggests we should reconsider doing this procedure on people who have more mild pain, and less severe knee arthritis and loss of function," said Daniel Riddle. He's a professor of physical therapy and orthopaedic surgery at Virginia Commonwealth University. Some in the medical community wonder if the procedure is overused, said Riddle, who wasn't involved in the study. For now, "the jury is still out," he added. In 2010, total knee replacement was the most frequently performed inpatient procedure on U.S. adults aged 45 and older, according to the U.S. ... Read more

Obesity May Not Compromise Knee Surgery Success

Posted 24 Mar 2017 by Drugs.com

FRIDAY, March 24, 2017 – Weight doesn't seem to affect whether a common type of knee surgery will be successful, a new study shows. About 15 percent of meniscal repair surgeries fail, researchers said. It's been widely believed that patients with a higher body mass index (BMI) are at increased risk for failure because more weight puts more pressure on the knee. BMI is an estimate of body fat based on height and weight. But this study of 410 patients who had meniscal repair surgery found no significant differences in failure rates between those with a normal BMI of less than 25 (considered normal weight) and those with a BMI of between 25 and 35 (up to 29.9 is overweight, and above 30 is obese). An adult who is 5 feet, 9 inches tall has a normal BMI if their weight is between 125 to 168 pounds, according to the U.S. Centers for Disease Control and Prevention. If that same person weighs ...

ACL Surgery Usually Puts Athletes Back in Play: Study

Posted 23 Mar 2017 by Drugs.com

WEDNESDAY, March 22, 2017 – Most athletes who undergo reconstructive surgery for a torn anterior cruciate ligament (ACL) are able to return to sports, a new study says. Researchers from the Hospital for Special Surgery in New York City followed more than 200 athletes who had ACL reconstruction there between 2009 and 2013. An average of 10 months after surgery, nearly nine out of 10 patients had resumed their sport. Of those patients, 89 percent said they had returned to their prior level of competition, the researchers reported. "Our study found that patient satisfaction was very high after ACL reconstruction, and that satisfaction correlated highly with return to a sport," Dr. Benedict Nwachukwu said in a hospital news release. Overall, 85 percent were very satisfied with the results, and 98 percent said they would undergo the procedure again if necessary, the study found. The ACL is ... Read more

Smokers Prone to Problems After Joint Replacement: Study

Posted 16 Mar 2017 by Drugs.com

THURSDAY, March 16, 2017 – Quitting smoking before knee or hip replacement surgery may cut the risk of complications after surgery, a new study suggests. Instead of just telling people to quit smoking, these findings suggest that doctors should guide people into pre-surgery smoking-cessation programs for smokers, the researchers said. "We've known that smokers do worse than non-smokers after joint replacements, and now this research shows there's good early evidence that quitting smoking before surgery may improve their outcomes," said study author Dr. Amy Wasterlain. She's a fourth-year orthopaedic surgery resident at NYU Langone Medical Center in New York City. "Not every risk factor can be reduced before a joint replacement, but smoking status is one that should be a top priority for orthopedic surgeons and their patients," she added in an NYU news release. The study included more ... Read more

Home Beats Rehab for Knee, Hip Replacement Recovery

Posted 16 Mar 2017 by Drugs.com

THURSDAY, March 16, 2017 – Patients who go straight home from the hospital following hip or knee replacement surgery recover as well as, or better than, those who first go to a rehabilitation center, new research indicates. And that includes those who live alone without family or friends, one of three studies shows. "We can say with confidence that recovering independently at home does not put patients at increased risk for complications or hardship, and the vast majority of patients were satisfied," said that study's co-author, Dr. William Hozack. He is an orthopaedic surgery professor with the Rothman Institute at the Thomas Jefferson University Medical School in Philadelphia. Hozack noted that while in the past it was "not uncommon for patients to enter a rehabilitation facility in order to receive additional physical therapy," most patients today do not end up going to a secondary ...

Some Hospitals May Overcharge for Hip, Knee Replacements: Study

Posted 28 Feb 2017 by Drugs.com

TUESDAY, Feb. 28, 2017 – Some U.S. hospitals might be charging private insurers twice as much for knee and hip replacements as the implants typically cost, new research suggests. It's not clear why the discrepancy exists, and an official with a national trade association of hospitals cautioned against drawing too many conclusions from a finding that only involved one insurer. Still, study co-author Dr. Kenneth Mandl said the results raise questions, especially regarding the fact that insurers aren't told how much the implants actually cost the hospitals. "Billions of dollars are at stake when the true cost of the devices are hidden," said Mandl, director of the Computational Health Informatics Program at Boston Children's Hospital. Mandl said his team wanted to find out what happens when hospitals charge private insurers for joint implants without disclosing the model numbers or cost. ... Read more

High-Mileage Runners Expend Less Energy

Posted 27 Jan 2017 by Drugs.com

FRIDAY, Jan. 27, 2017 – The bodies of runners who put in a lot of mileage appear to be more efficient at running compared to those who run less, a new study finds. Jasper Verheul and colleagues at Liverpool John Moores University in the United Kingdom compared two groups of runners. One group ran more than 27 miles a week, the other group ran fewer than nine miles a week. The researchers examined the activity of muscle groups in the thigh and the motion of knee joints with a variety of tools as the participants ran at different speeds. "Given the importance of the knee joint in running, it was hoped that by examining knee joint stiffness and muscle activation levels across a range of running speeds, the adaptations of neuromuscular factors due to running training could be closely explored for the first time," the researchers wrote. When their feet landed on the ground, the knees of the ... Read more

Joints That Make Those Popping or Cracking Sounds

Posted 27 Jan 2017 by Drugs.com

FRIDAY, Jan. 27, 2017 – If you've ever heard a loud pop as you bent down to pick something up, you'll be relieved to know that it's normal for your joints to make popping and cracking noises. These sounds can be caused by a number of things, including when soft tissues – such as tendons and ligaments – rub or snap over other tissues and bones, explained Dr. Aman Dhawan. He is an orthopedic sports medicine specialist at Penn State Health's Milton Hershey Medical Center. "Our joints are mobile, so there are a lot of things that slide over or run past each other. When they move, there is the potential for anatomy to intersect," he said in a Penn State news release. The sounds can also be caused by pockets of nitrogen gas within the fluid that helps lubricate joints and provides nutrition to cartilage, Dhawan added. According to Dr. Robert Gallo, another orthopedic sports medicine ... Read more

Work Disability Benefits? Depends on the Doc

Posted 26 Jan 2017 by Drugs.com

THURSDAY, Jan. 26, 2017 – Medical professionals give widely varying opinions about whether claimants for work disability benefits should get those benefits, researchers report. After a disabling illness or injury, many workers seek benefits to replace their lost wages. Insurers provide benefits for employees who are evaluated and deemed eligible. Medical professionals are hired by insurers to evaluate these employees, but there have been concerns about the quality of these evaluations, the researchers explained. The research team, led by Dr. Regina Kunz from the University of Basel in Switzerland, analyzed 23 studies conducted between 1992 and 2016 in 12 countries in North America, Europe, Australia, the Middle East and Asia. In 63 percent of the studies, there was only low to moderate agreement in medical experts' opinions about disability benefits claimants' ability to work. Higher ... Read more

Joints Achy? Don't Blame Mother Nature

Posted 10 Jan 2017 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 5 Jan 2017 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
