The Impact of Two Different Physical Therapy Programs in the Rehabilitation of Patients Undergoing Anterior Approach Hip Replacement Surgery

Study Overview
=================
Brief Summary
-----------------
This study will look to determine two different types of physical therapy regimens in patients who undergo anterior total hip replacement. We will compare the results of two groups. The first group, the Formal Physical Therapy group, will undergo standard physical therapy following their surgery. They will see a physical therapist in a physical therapy office after their surgery. Here, the therapist will work with the patient to strengthen muscles and improve their walking. The second group, the Self-directed Physical Therapy group, will undergo physical therapy in the comfort of their own home using common household items (chairs, steps, etc). These patients will be given a list of exercises and stretches to perform on their own. It is our goal to prove that formal physical therapy is not needed after anterior hip replacements.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change inHarris Hip Score (HHS) | elf-administered health survey that assesses pain, function, absence of deformity, and range of motion of the hip through 10 questions. HHS measures dysfunction, so a higher score indicates a better, higher functional outcome. Less than 70 is poor result, 70-80 ia fair result, 80-90 is good result, 90-100 is excellent result | assessed 1,3,6, and 12 months after total hip replacement to assess change at each time point following surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in timed up and go test | Patients will be assessed the amount of time it takes for them rise from a standard arm chair, walk 10 feet on the floor at normal pace, and then return and site down in same standard arm chair. Duration to complete task will be recorded in seconds | assessed 1,3,6, and 12 months after total hip replacement to assess change at each time point following surgery | 
| Change in Visual Analog Scale for Pain | Patients will rate their pain on a scale form 0-10 at a given time point with 0 being no pain and 10 being unbearable pain. The higher the number, the more pain | assessed 1,3,6, and 12 months after total hip replacement to assess change at each time point following surgery | 
| Change in Western Ontario and McMaster University Osteoarthritis Index (WOMAC) form | Self-administered health survey that assesses pain, stiffness, and function of arthritis of the hip or knee. WOMAC form assesses activities of daily living, functional mobility, gait, general health, pain, and quality of life. WOMAC questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). A total score of 0 to 96 is possible, with a lower score indicating less pain or disability. | assessed 1,3,6, and 12 months after total hip replacement to assess change at each time point following surgery |
