Advanced rehab after knee replacement surgery provides long-term benefits to those who receive it, according to a study conducted by Kenneth Ottenbacher, director of the Center for Rehabilitation Sciences at UTMB. The research team examined data from 12,199 men and women who had knee and hip replacements between 2008 and 2010. All of the research subjects were living independently prior to the surgery and underwent rehab as inpatients. Most of the participants were female. Their average age was 71. The study was published in the Archives of Gerontology and Geriatrics.
