According to a new study, gaining just 11 pounds can increase your risk of needing a knee replacement surgery. The additional weight places stress upon the joint, weakening it over time.
Even in cases where surgery isn’t required, weight gain can lead to pain and stiffness within the knee. This can limit your ability to carry out daily tasks. Here, we look at what the new study found and other factors that contribute to poor knee health.
Small weight gain increases risk of knee surgery in men and women
The latest study, carried out by researchers from the Monash University in Australia, showed that the weight-related risk of needing a knee replacement applied to both men and women. An 11-pound weight gain in women results in a 34% increased risk, while in men it increases by 25%.
A total of 20 previous studies were assessed as part of the research. Each of these studies had investigated the link between Osteoarthritis and weight gain. It was determined that Osteoarthritis was more likely to occur, and progress at a faster rate, due to weight gain.
The results of the research have been presented at the Melbourne International Congress on Obesity.
The link between knee surgery and weight
Experts have known for a long time that there is an association between weight and arthritis in the knee. You probably don’t even think about it, but the knee joints are almost constantly under significant pressure. When you add extra weight, it is only a matter of time before the joints begin to buckle.
Being just 11 pounds overweight, adds approximately 20-30 pounds of extra force onto the knee joint. Eventually, the tissue of the cartilage can begin to erode, causing arthritis to develop.
The good news is, losing just 10 pounds can help to reduce the risk. The study showed that losing up to a stone can reverse the risks of requiring knee surgery.
Other factors that lead to poor knee health
It isn’t just excess weight that can cause issues for the knee. Genetics, your job, and how long you spend walking around each day can all contribute to poor knee health.
Some people are also known to be more susceptible to inflammation and pain in the knee joint than others. The reason for this is currently unknown.
If you are experiencing knee problems, book a consultation with Mr Jonathon Webb today. While there is no cure for arthritis, there are many treatments you can undergo to manage the condition. Surgery is typically only required in severe cases where the patient’s day to day life is significantly impacted.
