Knee pain is a common problem that generally affects people of all ages. Generally, the knee joint is particularly susceptible to pain and damage as it is the joint that takes the entire body weight. This is probably one of the main reasons that overweight people have more chances of developing this condition. It occurs mainly due to an injury such as ruptured ligament or torn cartilage. In addition, this can occur due to several other medical conditions such as arthritis, gout or other infections related to the joint. The location of the pain and severity of symptoms may vary from one person to another and may depend on the cause of the problem as well.
According to a new study, bariatric surgery and the subsequent weight loss may potentially reduce knee complaints in morbidly obese adults. The study results (though limited) were published online in Obesity Reviews (December 2014 issue).
As part of the study, researchers analyzed data results from 13 studies involving more than 3,837 patients receiving bariatric surgery. The study involved the usage of one or more assessment tools to determine the potential effects of this surgery in morbidly obese patients having knee complaints. A significant improvement was found in overall knee pain in about 73% of all the assessments. All those studies that analyzed the knee pain intensity, knee physical function and knee stiffness reported considerable improvements.
The study results signify that bariatric surgery with successive marked weight loss is likely to reduce chronic knee pain and swelling in obese patients. However, with the available limited evidence, researchers point out the need for further studies to be conducted in this area.
