Effect of Preoperative Exercise in Patients Undergoing Total Knee Arthroplasty

Study Overview
=================
Brief Summary
-----------------
This study evaluates the effect of preoperative exercise in patients undergoing a total knee arthroplasty.

Detailed Description
-----------------
The objectives of this study were to investigate the effects of a single (9 sessions) prescription community based preoperative physical therapy in patients awaiting a Total Knee Arthroplasty, taking prognostic factors into account. The investigators will use different outcome measures to evaluate any possible effects.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Stair climbing test | The stair climbing test (SCT) measures the time used to ascend and descend a flight of twelve steps. Patients are asked to complete the test as quickly as they felt safe and comfortable. | 5 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Knee - Range of Motion | The range of motion of the knee will be assessed. | 2 minutes | 
| Tegner Activity Scale and Lysholm Score | The Lysholm score and the Tegner activity scale are widely used for assessing knee function and activity level after knee ligament injuries | 10 minutes | 
| Patient Global Impression of Change | The self-report measure Patient Global Impression of Change (PGIC) reflects a patient's belief about the efficacy of treatment. | 2 minutes | 
| Risk of Discharge to a Rehabilitation Facility | Costs and duration of postoperative rehabilitation will be measured with help of a personal calendar. All participants will report on this calendar any post-acute care services after surgery, Costs of skilled nursing facilities, home health agencies, and inpatient rehabilitation. | 20 minutes |
