Overview
Brief Summary
The purpose of this study is to examine the effects of two technology interventions on health outcomes (e.g., physical activity, sedentary behavior, physical function, pain) after knee replacement at 2 and 5 months .
Detailed Description
Two 8 week technology interventions will be examined and consist of the use of an app and/or website and regular calls. Assessments to examine outcomes will be completed at baseline, as well as at 2 and 5 months.

Outcomes
Primary Outcomes
Change in Objectively Measured (Actigraph) Sedentary Behavior at 5 months
Time Frame: 5 months - baseline
