Outcome Measures
Primary Outcomes (3)
Minutes of Moderate to Vigorous Intensity Physical Activity
Minutes of moderate to vigorous intensity physical activity assessed by Actigraph accelerometers
baseline to 3 months
Pain Intensity
Pain intensity assessed by Patient-Reported Outcomes Measurement Information System pain intensity survey. 0 represents no pain and 10 reports the most severe pain
baseline to 3 months
Self-reported Physical Function
Physical function assessed by Patient-Reported Outcomes Measurement Information System (PROMIS) physical function/mobility survey. A t-score of 0 represents poor function compared to average and 100 represents better function. A t-score of 50 indicates the population mean with a standard deviation of 10.
baseline to 3 months
Secondary Outcomes (3)
Minutes/Week of Moderate to Vigorous Intensity Physical Activity
3 months to 6 months

Study Arms (2)
Energize!
EXPERIMENTALParticipants randomized to Energize! will start the program immediately after baseline.
Delayed Energize!
OTHERParticipants randomized to Delayed Energize! will start the program after the 3 month assessment.
Interventions
Energize! is 3 month online physical activity program which consists of weekly physical activity goals, video lessons, action planning, and homework.

You may qualify if:
- Have had a partial or total knee replacement ≥12 months ago
- Have regular access to the internet
- Willing to wear activity monitor for 7 days at baseline, 3 \& 6 months
- Engage in less than 60 minutes of self-reported moderate intensity exercise
You may not qualify if:
