Because the variety of whole knee alternative (TKR) surgical procedures proceed to climb, a examine out of Queensland, Australia factors at a doable main trigger — and with it a doable resolution.
Weight problems and weight achieve, the
Utilizing information from the Australian Bureau of Statistics’ (ABS) 2017-18 Nationwide Well being Survey with the Australian Orthopaedic Affiliation Nationwide Joint Substitute Registry, researchers discovered that, of the 56,217 Australian TKR sufferers in that timeframe, 57.7 p.c had been overweight.
TKR sufferers who had been overweight had been additionally a mean of seven years youthful than sufferers who weren’t overweight.
Moreover, ladies ages 55 to 64 with weight problems had been 17 occasions extra more likely to want TKR than those that weren’t overweight.
Males dwelling with weight problems had been 5.8 occasions extra more likely to want TKR than their friends who weren’t overweight.
These statistics ring true, orthopedic surgeons say.
“We now have a silent impending epidemic,” Dr. Scott Oliver, orthopedic surgical procedure specialist at Beth Israel Deaconess Plymouth in Massachusetts, instructed Healthline.
“And with weight problems projected to proceed to extend, that is solely going to extend as properly,” he mentioned.
Oliver mentioned weight has a selected influence on the knee joint, much more so than the hip.
He mentioned that 4 issues usually result in knee joint injury. They’re genetics, overuse, trauma, and extreme weight. He added that these items can injury joints in any mixture collectively or individually.
The overall assertion, he mentioned, is that each added pound over a wholesome weight can add 4 kilos of stress to a weight-bearing joint just like the knee.
“We see it increasingly more in youthful individuals, and it’s not going away,” he mentioned.
That’s what impressed Dr. Chris Wall, deputy director of the Division of Orthopaedics at Queensland School, to conduct the examine.
“A big proportion of the sufferers that I see in clinic with knee osteoarthritis are overweight. Equally, a big proportion of sufferers that I carry out knee replacements on are overweight. This sparked my curiosity,” he mentioned.
Why does weight influence the knee joint so profoundly? Wall mentioned the reply isn’t as clear lower as individuals might imagine.
“The standard idea was that extra physique weight affected the knee in a purely mechanical trend. Nonetheless, current analysis has demonstrated that the affiliation between weight problems and knee osteoarthritis is way more complicated. The affiliation continues to be not totally understood, however it’s in all probability a mix of genetic, biochemical and metabolic elements, in addition to mechanical overload,” he defined.
Regardless of the rising want for knee TKR surgical procedures, Wall mentioned the examine does spotlight potential excellent news too: prevention will help scale back the chance.
“Earlier analysis has proven that modest weight reduction — 10 p.c of physique weight — considerably improves the signs of knee osteoarthritis and reduces the chance of needing a knee alternative,” Wall mentioned.
He mentioned he’s met many sufferers with weight problems and knee osteoarthritis who misplaced some weight and their knee signs improved to the purpose that they not wanted a knee alternative.

He mentioned that surgical procedure ought to all the time be a “final resort,” reiterating that weight reduction can usually “decelerate or cease development” towards needing a TKR if motion is taken early sufficient.
Each Wall and Oliver identified that TKR surgical procedure alone can’t repair the difficulty. If an individual’s weight problems isn’t handled, the additional weight will put on down the newly changed joint.
“Sadly, weight problems will increase the chance of short-term and long-term problems after knee alternative,” Wall mentioned.
Among the many potential problems is the chance of an infection after TKR surgical procedure, which is ten occasions greater for many who reside with weight problems.
Oliver mentioned this may imply far more than merely needing an additional spherical of antibiotics. In lots of instances, an an infection would require the TKR to be eliminated and changed with one other surgical procedure.
He mentioned these issues are sometimes a part of the dilemma with TKR surgical procedures for individuals with weight problems.
“We don’t wish to put the affected person in danger,” he mentioned.
Oliver mentioned he feels that treating weight problems is the important thing to lowering the necessity for TKR surgical procedures. He pointed to analysis which initiatives that knee accidents resulting from weight problems will soar to 70 p.c by the top of the last decade.
“We’re seeing it in youthful and youthful individuals, and it’s not going away,” he mentioned.
Wall agreed that it’s a problem that wants consideration and motion at the next stage.
“I believe the important thing message is that we have to tackle the difficulty of weight problems at a inhabitants stage, together with a robust give attention to prevention,” he mentioned.
