WASHINGTON — Stomach-narrowing surgery does not just augment your beauty but also aids in easing the chronic knee pain, according to a NYU School Of Medicine-led study.
The pain, according to the study leaders at NYU School of Medicine, proceeds from the deterioration and related inflammation in knee joints caused in part by the extra weight they bear.
And, while the pain relief seen with lap-band surgery applied to all patients with osteoarthritic knees, researchers found that it was most helpful in the youngest men and women who lost the most weight.
“Our study shows that extremely obese people seeking relief from their knee pain should consider lap-band surgery earlier because the benefits from it being successful — although significant for all ages — decrease with age,” said study senior investigator, Jonathan Samuels,Associate Professor at NYU School of Medicine.
For the study, published in the journal Seminars in Arthritis and Rheumatism, researchers examined 120 patients who underwent lap-band surgery between 2002 and 2015.
Samuels said it is likely that knee joints and cartilage become so damaged after a certain point that there is little cushion left for weight loss to preserve. Along these lines, the research team found that people in their 40s reported nearly twice as much pain relief after lap-band as those who had the surgery in their 50s.
More than 130,000 Americans have had the procedure done since 2011, national statistics show. Although the operation is considered relatively safe, complications may include nausea, stomach ulcers, and infection.
The study authors said their findings are especially important because one in three American adults is now overweight. Studies also showed that the number of Americans with osteoarthritis has more than doubled since World War II.
The new analysis was based on the experiences of 120 patients at NYU Langone Health who underwent lap-band surgery between 2002 and 2015. All were surveyed about what they remembered about their knee pain immediately before surgery, a year after their procedure, and for as long as 14 years later.
The main purpose of the survey, researchers said, was to find out why some extremely obese people showed more knee-pain relief from lap-band surgery than others.
Study participants had an average body mass index, or BMI, of 40, which equates to a 5 feet and 10 inches-tall man who weighs about 280 pounds, or a 5 foot 6 inches-tall woman who weighs 250 pounds.
According to the survey results, men and women in their 40s experienced postsurgical knee pain reductions after one year of between 50 percent and 60 percent; while those in their 50s, one year later, had pain reductions between 30 percent and 40 percent; and those in their 60s, had reductions between 20 percent and 30 percent. Pain relief persisted for a decade in all patients monitored.
Results also showed that BMI at the time of surgery did not influence whose knee pain went down the most. People with BMIs in the upper 40s were just as likely to report decreased knee pain as people with BMIs in the lower 40s if they lost proportionally the same amount of total body weight.

Suicide can’t be predicted by asking about suicidal thoughts : Study
Most people who died of suicide deny they experience suicidal thoughts when asked by doctors in the weeks and months leading up to their death, a major Australian study has found.
The findings, co-authored by clinical psychiatrist and Professor Matthew Large from UNSW’s School of Psychiatry, Sydney that published in the journal BJPsych Open The meta-analysis challenge the widely-held assumption that psychiatrists can predict who will suicide by asking if they are preoccupied with thoughts of killing themselves.
The study showed that 80% of patients who were not undergoing psychiatric treatment and who died of suicide reported not to have suicidal thoughts when asked by their psychiatrist or GP.
“If you meet someone who has suicidal ideation there is a 98 per cent chance that they are not going to suicide,” said Professor Large, an international expert on suicide risk assessment who also works in the emergency department of a major Sydney hospital.
“But what we didn’t know was how frequently people who go on to suicide have denied having suicidal thoughts when asked directly,” he added.
“This study proves we can no longer ration psychiatric care based on the presence of suicidal thoughts alone. We need to provide high-quality, patient-centred care for everyone experiencing mental illness, whether or not they reveal they are experiencing suicidal thoughts,” Professor Large said.
About one in 10 people will have suicidal ideation in their lifetime. But the study showed suicidal ideation alone was not rational grounds for deciding who gets treatment and who does not, Professor Large said.
“We know that suicide feeling is pretty common and that suicide is actually a rare event, even among people with severe mental illness,” Professor Large added.
Suicidal ideation tells us an awful lot about how a person is feeling, their psychological distress, sometimes their diagnosis and their need for treatment but it’s not a meaningful test of future behaviour.
Suicidal feelings can fluctuate rapidly and people may suicide very impulsively after only a short period of suicidal thoughts.
But, people had good reasons not to disclose thoughts of suicide, fearing stigma, triggering over-reactions or upsetting family and friends, and being involuntarily admitted for psychiatric treatment, Professor Large said.
Professor Large emphasized that clinicians should not assume that patients experiencing mental distress without reporting suicidal ideas were not at elevated risk of suicide.
