Do people fare better after knee surgery with at-home exercise or clinic-based physical therapy (PT)? That is the question posed in a 2014 Australian study in the journal Arthritis Care & Research. Researchers found that those patients who had total knee replacement and followed a structured, at-home exercise program did no worse – in terms of pain and range of motion – than those who participated in a standard clinic-based physical therapy program.
According to the Centers for Disease Control and Prevention, more than 700,000 knee replacement surgeries, also called total knee arthroplasty, are done every year. That number is expected to rise as the population ages and grows heavier.
