A Harvard study published in the Journal of the American Medical Association shows that while there is a growing rate of knee replacements among seniors, the rates of complications for these patients is rising as well. The study followed 3.3 million Medicare patients aged 65 and older between 1991 and 2010, finding that the amount of total knee arthroplasty (TKA) increased 162 percent from 93,230 to 243,802 in the United States.

According to the study, surgeons who perform the bulk of these procedures often do fewer than 12 a year. At the same time, infection rates following surgery increased from 1.4 to 3 percent during the course of the study. According to research published in Rheumatology, joint injuries as a young adult are some of the primary causes for knee replacement surgeries later in life. Meniscal injuries during middle age were also cited as common causes, along with musculoskeletal deconditioning as a result of aging.

His 2010 study, published in the journal Immunity, found no side effects of the treatment, which also had anti-inflammatory effects. |
