Exercise after knee replacement critical
Date:2/2/2009

lthy people of the same age.

In a randomized controlled trial at the University of Delaware's Physical Therapy Clinic conducted between 2000 and 2005, 200 patients who had undergone knee replacements were given six weeks of progressive strength training two or three times a week starting four weeks after surgery. Half of the group also received neuromuscular electrical stimulation (NMES).

Their function was compared to that of 41 patients who received conventional rehabilitation and home physical therapy. Quadriceps strength, knee range of motion, and gait were measured in such tests as timed up and go, stair climbing and a six-minute walk.

The group in the progressive strength-training program showed significant improvement in quadriceps strength and functional performance. They also demonstrated substantially greater quadriceps strength and functional performance after 12 months than the group that underwent conventional rehabilitation.

"This study clearly demonstrates the importance of surgeons encouraging their patients to be compliant with progressive quadriceps strengthening during their rehabilitation to enhance their clinical improvement and function post-total knee replacement," notes Dr. Leo Raisis, a total joint surgeon and adjunct associate professor at the University of Delaware.

"Why undergo a $25,000 elective surgery and then not do as much as you can to get the most out of it and improve your quality of life?" Snyder-Mackler says. "Older people are incredibly motivatedthey hurt after the surgery and they want to be better. They need to do this."
