Collaborative-care Intervention to Promote Physical Activity After Total Knee Arthroplasty

Detailed Description
More than 650,000 total knee arthroplasties (TKAs) are performed annually to alleviate pain and disability associated with osteoarthritis (OA); a chronic, degenerative condition that compromises the quality of life of 37% of adults over age 60. With the aging of the population, an estimated 3.5 million TKAs will be performed annually by 2030. Despite improvements in pain and self-reported function, physical activity after TKA remains at pre-operative, sedentary levels (<5,000 steps/day). Physical activity in TKA confers powerful protective effects against common post-surgical sequelae including increased weight gain (mean=6.4 kg, 2 years post TKA), decreased functional performance, increased risk/progression of co-morbid conditions (e.g. type 2 diabetes mellitus, cardiovascular disease), and progression of knee and hip osteoarthritis which may necessitate additional joint replacement in the contralateral limb. An intervention aimed at improved self-management of physical activity may aid patients in overcoming habitual lifestyle patterns of low physical activity secondary to knee pain prior to TKA.
Recent investigations on the effects of real-time, user-friendly, electronic physical activity feedback (PAF) systems and face-to-face (FTF) patient group meetings aimed to promote self-management of physical activity suggest that such interventions can successfully increase physical activity. Therefore, the investigators propose a randomized, controlled trial to assess efficacy and feasibility of a physical activity intervention combined with FTF group meetings (PAF+FTF) initiated within one month of patients' discharge from outpatient rehabilitation for TKA compared to a control group receiving standard care (CON). This type of intervention is surprisingly novel to this patient population and is not common practice in rehabilitation following TKA.

Experimental: Physical Activity Feedback
The physical activity feedback intervention will involve real-time physical activity monitoring using a device to provide activity feedback directly to patients in combination with patient group meetings held monthly during the 12 week intervention for the purposes of mutual support in attaining physical activity goals.
