Knee osteoarthritis is one of the most common causes of disability in older adults. Total
knee replacement (TRK) surgery is often an effective solution when persistent pain does not
sufficiently improve with non-surgical treatment. Although most TKR surgeries are a success,
an estimated 15% to 30% of patients report no clinically significant improvement in function
12 months after a TKR. This study will evaluate the effectiveness of a patient support
program in increasing physical function after a TKR surgery.
Each year, more than 350,000 adults elect to have TKR surgery to eliminate knee pain and
associated disabilities that persist despite ample medical treatment. Common knee problems
of people who undergo TKR surgery include osteoarthritis, rheumatic diseases, and sudden or
gradual joint injury. Most people who undergo TKR surgery experience immediate and
significant decrease in pain, improved joint function, and increased physical activity.
However, not all people who undergo TKR surgery report improvement, and there is no one
factor that contributes to this variation in functional gain. With the rapid growth in the
number of people electing to have TKR surgery and in the number of candidates eligible for
TKR, optimal surgical results are both a clinical and public health priority. This study
will evaluate the effectiveness of a patient support program emphasizing exercise and
emotional health in increasing physical function after TKR surgery.
Participants in this study will be randomly assigned to a TKR patient support program or
treatment as usual. The intervention patients will receive a program designed to complement
the intensive physical rehabilitation period.
Sessions will aim to help participants enhance their self-management skills for behavior
change.
Inclusion Criteria:

Center's surgeons prior to study entry
Exclusion Criteria:

surgery

- Co-existing conditions that would negate functional improvement with surgery and
exercise
- TKR surgery scheduled on an emergency basis
- Scheduled for TKR surgeries of both knees at the same time
- Terminal illness with a life expectancy of less than 1 year
- Inability to provide informed consent due to dementia or cognitive impairment
- Planning another TKR or THR surgery within 6 months of study entry
- Unavailable to complete study procedures (i.e., will be out of the region during the
rehabilitation period)
