A Rehabilitation Tool to Determine Patient's Stay in Hospital After Joint Replacement

Study Overview
=================
Brief Summary
-----------------
This is the research study of a rehabilitation tool that informs, guides and empowers clinicians to care for their patients. We hope to learn ways to improve patient outcomes, reduce costs and increase value to the healthcare system

Detailed Description
-----------------
The investigator hope to learn co-relation between the rehab tool and clinical findings and analyse association if any. Rehab tool will optimize care according to the patient's specific needs and provided insights to patients length of stay in the hospital. these data driven insights will be used to observe correlation between machine and clinic data

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental<br>The application used is build upon the company's category-defining, FDA- cleared Virtual Exercise Rehabilitation Assistant (VERA™) and create a platform that streamlines the performance and management of post-acute care physical therapy. The rehab tool will provide us with functional outcome score. | Device: VERA clinic<br>* A software system used with the Microsoft Kinect intended to support the physical rehabilitation of adults in the clinic and at home.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Length of Stay in Hospital Through Discharge |  | Up to 2 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Requiring Gait Aid Use | The gait aide use ranges in the order of decreasing performance as Nothing > Cane > crutch > walker. | 3 months post operative visit | 
| Knee Society Score (KSS) | To assess the effectiveness of the device by calculating knee society score (KSS) after surgery. The scale ranges from 0-100 with grading as Score 80-100 - Excellent Score 70-79 - Good Score 60-69 - Fair Score below 60 - Poor | 3 months post operative visit | 
| Knee Range of Motion | To assess the effectiveness of the device by calculating range of motion (maximum degrees) | 3 months post operative visit |
