Primary Outcome Measures:
- Exercise Adherence [ Time Frame: Average adherence over the 24 month follow-up period. ] [ Designated as safety issue: No ]In the literature, adherence is assessed on a continuum as the number of sessions of exercises reported divided by prescribed. This does not provide information on how consistent a participant was in doing exercise and consistency of strength training is critical to its effectiveness. We developed a measure of adherence that reflects consistency, choosing a threshold of a minimum of 1 time per week for 80% of the weeks. An 80% threshold permits vacations/illness/life events that may limit exercise opportunities. We will also measure adherence by exercise sessions performed/sessions prescribed.
Secondary Outcome Measures:
- Instruments [ Time Frame: Change in self-report pain and function from baseline to the 24 month interval. ] [ Designated as safety issue: No ]The Western Ontario/McMaster Universities Osteoarthritis Index (WOMAC), National Institutes of Health, Patient Reported Outcomes Measurement Information System (NIH PROMIS) for physical function, and the Osteoarthritis computer adaptive test methodology (OA-CAT) instrument will be assessed at baseline, post the 1-month exercise class, at the 12 and 24 month follow-up clinic visits and by telephone at 6 and 18 months. We will examine the association of adherence, as a dichotomous and continuous variable, to change in pain and function on these instruments.
- Quadriceps strength [ Time Frame: Change in quadriceps strength from baseline to 24 months. ] [ Designated as safety issue: No ]Isokinetic quadriceps strength will be assessed with a Biodex at baseline, post the 1-month exercise class and at the 12 and 24 month follow-up clinic visits. The association of adherence as a dichotomous and continuous variable to change in quadriceps strength will be assessed.
- Timed Physical Function tasks [ Time Frame: Change in timed physical function task over 24 months ] [ Designated as safety issue: No ]Timed physical function tasks will include a timed get up and go, timed stair ascent and descent, and a 5 and 10 chair stand time. We will examine the association of adherence, as a dichotomous and continuous variable, to change in timed physical function using logistic and linear regression, respectively.
- Exercise quality [ Time Frame: Average measure of exercise quality over 24 months ] [ Designated as safety issue: No ]The outcome will be assessed at the end of the 24 month follow-up period as the number of calendar periods (1 month per calendar period) that the participant exercises at least half the number of prescribed sessions (a minimum of 6 out of 12 over a 4 week period) with the agreed upon level of intensity.

Experimental: Telephone-linked Communication (TLC)
This group will receive the computer-based telephone counseling.
Computer-based telephone linked communication will be used to counsel subjects to adhere to their exercise program over time.
No Intervention: Control
This is the control group. They will receive the exercise class, however, they will not receive the telephone counseling.
