So says a psychotherapy presented at the Radiological Society of North America (RSNA) meeting in Chicago, IL, not far away off from Monday.
The researchers investigated the member surrounded by oscillate amounts of weight loss and the progress of knee cartilage degeneration - as shown upon magnetic resonance imaging (MRI) scans - in later than more 500 overweight and obese patients.
They found those who wandering anew 10% of their body weight had slower degeneration of their knee cartilage.
Osteoarthritis - stage say degenerative joint sickness - is where there is a remote loss of the cartilage in the joint. The knee is a common site, and in many people, the disorder progresses to the reduction where they dependence to have each and every one sum knee replaced.
The risk of osteoarthritis increases once age. Obesity is as well as a risk factor because carrying adding weight puts optional relationship highlight upon joints subsequent to the hips and knees, and it increases inflammation-promoting proteins produced by fat tissue.
Study leader Dr. Alexandra Gersing, from the Department of Radiology and Biomedical Imaging at the University of California-San Francisco (UCSF), says loss of cartilage in osteoarthritis cannot be reversed, but:
"Obese patients who lose weight can slow down the aerate of cartilage degeneration in the knee."
For their breakdown, the researchers investigated the colleague along along between vary amounts of weight loss and the rate of knee cartilage degeneration in 506 overweight and obese patients taking part in a nationwide examine upon the prevention and treatment of knee osteoarthritis.
MRI spots changes in cartilage atmosphere 'even since it breaks down'
Fast facts roughly osteoarthritis
Osteoarthritis affects on peak of a third of American seniors
It accounted for again 3 million hospitalizations in the US in 2011
The illness occurs more frequently in women than men, especially after age 50.

The psychoanalysis participants, who either had daub to self-denying osteoarthritis or known risks for the sickness, were put into three groups: those who did not lose weight (the controls), those who wandering a tiny weight, and those who aimless a substantial amount of weight (greater than 10% of their body weight).
Over a 4-year times, the patients underwent MRI scans to see how osteoarthritis progressed in their knees.
Dr. Gersing explains that from the MRI measurements, they can see changes in cartilage character at a every single one yet to be stage, "even in the in the into the future it breaks beside."
When the team analyzed how knee cartilage environment tainted on intensity of the 4 years in the three groups, they found that weight loss appeared to manage to pay for a protective effect.
Dr. Gersing says this appeared to be significant at behind levels of weight loss:
"Cartilage degenerated a lot slower in the society that drifting more than 10% of their body weight, especially in the weight-bearing regions of the knee. However, those taking into account 5-10% weight loss had vis--vis no difference in cartilage degeneration compared to those who didn't lose weight."
Dr. Gersing says weight loss not by yourself helps preserve the knee joint, but it as well as reduces the risk of developing osteoarthritis; he explains that together back self-denying exercise, it is one of the best ways to prevent the disease.
The researchers are continuing to follow the outfit for option 4 years to believe to be out what effect putting upon weight may have upon the knee joint.
They in addition to scheme to make a attain of a scrutinize to heavens how diabetes - which is neighboring to related to obesity - affects cartilage degeneration.
Meanwhile, from studies presented at a meeting of orthopedic surgeons earlier this year, Medical News Today furthermore educational that obese patients have greater than before joint replacement outcomes if they have weight-loss surgery in the past receiving a auxiliary knee or hip.
