Optimizing Physical Activity Outcomes for Veterans After Total Knee Arthroplasty
Although total knee arthroplasty is an effective intervention for decreasing knee pain and
improving physical function, physical activity levels remain low up to a year after surgery.
This study will use mobile-health technology to deliver an intervention designed to improve
physical activity behavior for Veterans recovering from total knee arthroplasty. The study
will assess the effectiveness of using behavior-change intervention as a supplement to
conventional rehabilitation to improve physical activity. The intervention will be delivered
using home-based tablet computers for Veterans to have remote interaction with the researcher
and real-time physical activity feedback from a wrist-worn activity sensor.

This randomized clinical trial will assess the efficacy of using physical activity behavior
change intervention for Veterans recovering from total knee arthroplasty. Testing will occur
at baseline (before surgery), at intervention midpoint (8 weeks after surgery), end of
intervention (14 weeks after surgery), and 24 weeks after intervention. The primary outcome
is accelerometer-assessed daily step count. Secondary outcomes include the percent time
engaged in standing and walking activity and physical function (Six-Minute Walk, 30-Second
Chair-Stand Test, Timed Up-and-Go, Western Ontario and McMaster Universities Osteoarthritis
Index, and the Veterans RAND 12-Item Health Survey.
