This study involves an exoskeleton which is believed to increase quadriceps muscle strength in the rehabilitation phase after TKA and reduce the discharge the such patients in Extended care facility (ECF) . The purpose of this study is to access efficacy of the robotic exoskeleton device wrapped around the operated knee on patients

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| robotic exoskeleton device | Experimental | Patients who are scheduled to be discharged to a ECF will be asked if they would want to use the exoskeleton device ( for which safety and comfort has been established) instead of going for ECF. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Robotic exoskeleton device | Device | It is a non invasive and non significant risk medical device which wraps around operated knee to support motion. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Predicting discharge location after TKA | The objective of this study is to observe how many patients are not transferred to ECF in the post-surgery time period as a result of using a robotic exoskeleton on operated knee. We will list number of patients NOT going for ECF. | 2 years |
| Measure | Description | Time Frame |
|---|---|---|
| Evaluate the effectiveness of the robotic exoskeleton device at time of discharge | To assess the effectiveness of the device by evaluating the number of patients discharge with exoskeleton device along with Home Health Services all by using questionnaire | upto 2 weeks |
| Evaluate the effectiveness of the robotic exoskeleton device at time of discharge |
