Researchers recently found that knee replacement surgeries have doubled in Two decades, especially for aging individuals within the U.S.

According to CBS News, the amount of knee-replacement surgeries increased to just about 224,000 in 2010. While knee surgeries surged by 162 percent, surgeries to fix artificial knee joints increased by 106 percent during the same time. The study noted that the rise in obesity, as well as current financial practices, could increase the number of surgeries and costs related to operations in the future. The findings were recently featured in the Journal of the Ama (JAMA).

“There’s a huge percentage of older adults who are living longer and want to be active,” lead author Dr. Peter Cram, an associate professor of internal medicine in the University of Iowa, told CBS News.

The study centered on trends on total knee arthroplasty from 1991 to 2010 in the United States. Many seek knee surgeries as they possibly can result in improvements in quality of life and mobility. They also found that the patients were a bit older than 70 years of age. Med Page Today reported that lots of the patients were recipients of Medicare benefits. In 1991, there have been approximately 3 procedures for every 10,000 Medicare beneficiaries. This year, that increased to 5 procedures for each 10,000 Medicare patients.

In general, operations can keep patients within the hospital for a certain amount of your time. The researchers found that the average in time the hospital because of knee surgeries decreased from around eight days to 3.Five days. Many patients ended up being discharged to inpatient rehabilitation centers and skilled care. Despite the fact that there is a decline within the length of the remain at the hospital, the researchers discovered that there was an uptick in the quantity of patients who needed to be readmitted towards the hospital due to infection and issues related to their past knee procedure.

“This growth is probably driven with a mixture of factors including an expansion in the types of patients considered likely to benefit from TKA, an aging population, as well as an increasing prevalence of certain conditions that predispose patients to osteoarthritis, most notably obesity,” the authors wrote in the article.

However, recently, the speed for that knee replacement surgery has slowed a little. The scientists think that the decrease may be due to teenagers who opt to have artificial knees instead of knee replacement. The weak economy has also led to less demand for the surgery.

Lastly, the financial costs of knee surgeries were highlighted within the study. They reported that $9 billion had accrued from the 600,000 knee surgeries completed in a year. Particularly, one surgery can cost approximately $15,000. An editorial accompanying the content in JAMA also noted that there should be more regulation around the operations. The author of the editorial estimated by 2030 there would be a yearly need for 4 million knee surgeries.

“When you multiply $15,000 by that amount of procedures you’re referring to major money even by federal Medicare standards which is a genuine challenge for that authorities,” Cram commented inside a video clip supplied by the journal.
