Total Knee Replacements Increase Mobility And Motor Skills In Older Patients
According to a new study from researchers at Duke University, total knee arthroplasty (TKA) procedures performed in older patients with osteoarthritis of the knee result in long-term, significant improvement of physical functioning and motor skills when compared to patients who do not receive TKA.
Published in the July 2009 issue of Medical Care, the study examined physical functioning and gauged outcomes in a national sample of Americans aged 65 and older for up to four years-a longer period than previous TKA studies. Relative to the untreated comparison group, recipients of total knee replacements experienced significant improvement in function, including a 17.5% increase in mobility, a 39.3% improvement in motor skills; and a 46.9% decrease in limitations in activities of daily living such as bathing and dressing oneself.
The number of total knee replacements performed in the United States has increased dramatically since 1990; currently 581,000 such procedures are performed every year. This number is expected to increase markedly as Baby Boomers age.
