Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study will be to find out the effect of two different interventions on muscle strength, ability to produce muscle force quickly (power), daily function, and number of steps and physical activity an individual with total knee replacement do daily.

The research hypotheses for this study will be as follows:

* For individuals who are at least 6 months post-total knee replacement, home-based high-velocity training exercises will result in significantly greater improvements in muscle strength and power compared to those who receive a walking program only.
* For individuals who are at least 6 months post-total knee replacement, home based high-velocity training exercises will result in significantly greater improvements of daily function(eg. sit to stand, climb a set of stairs)than those who receive a walking program only.
* For individuals who are at least 6 months post-total knee replacement, home based high-velocity training exercises will result in significantly greater improvements in physical activity behavior (eg. number of steps per day)compared to those who receive a walking program only.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group

Home exercise program plus walking program during 8-week period

Group Type EXPERIMENTAL

Exercises plus walking program

Intervention Type OTHER

Exercise group Consist of functional exercises such as mini-squats, sit to stand, and exercises with use of thera-bands. For each exercise, participants will be taught to perform the concentric phase forcefully and as fast as they can and return to the initial position slowly and with control. Participants will be asked to perform the exercises 3 times per week as a home exercise program daily throughout the 8-week intervention period. Additionally, they will be asked to wear a pedometer daily throughout the 8-week intervention to monitor steps. A step goal will be provided to gradually increase daily to become "somewhat active" or "active" by the end of the 8-week intervention.

Comparison group

Walking only program throughout the 8-week period.

Group Type ACTIVE_COMPARATOR

Walking only program

Intervention Type OTHER

Participants will be asked to wear a pedometer and instructions for use just as the exercise group. They will also will given a step goal just as the participants in the exercise group and will similarly be asked to record number of steps form their pedometer in a daily log along with the minutes of moderate and vigorous physical activity throughout the 8-week intervention period.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Men and women who are at least 40 years of age will qualify if they had a primary unilateral total knee replacement (TKR) 6 to 18 months.

Exclusion Criteria

* other lower extremity prosthetic implants other than the current TKR
* revision TKR or plan for revision
* diagnosis of severe osteoarthritis in the uninvolved knee or either hip joints
* recent low extremity injury or significant pain that increases during weight bearing or other functional performance
* diagnosis of neurologic deficits
* decreased cognitive status that might affect the ability to follow instructions
* significant cardiovascular and/or pulmonary disease that limits function
