Clinical Trial Summary

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

Outcome

Type Measure Description Time frame Safety issue
Primary 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
Secondary 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
Secondary Evaluate the effectiveness of the robotic exoskeleton device at time of discharge We plan to determine patient length of stay in hospital ( in hours) upto 2 weeks
Secondary Evaluate the effectiveness of the robotic exoskeleton device at time of discharge Determining patients performance of Stairs at discharge. Patients at the time of discharge are asked to step 3 stairs and answer related questions using a questionnaire upto 2 weeks
Secondary Evaluate the effectiveness of the robotic exoskeleton device at time of discharge through 2 years To assess the effectiveness of the device by calculating Initial knee society score (KSS) and Knee society score at 2 weeks, 3 months and 2 years 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 up to 2 years
Secondary Evaluate the effectiveness of the robotic exoskeleton device at time of discharge through 2 years To assess the effectiveness of the device by calculating initial Range of motion ( ROM) at the time of discharge and at 2 weeks, 3 months and 2 years after surgery. up to 2 years
Secondary Evaluate the effectiveness of the robotic exoskeleton device at time of discharge through 2 years To assess the effectiveness of the device by examining Gait Aide use at discharge, 2 weeks, 3 months and 2 years after surgery. This is done to examine performance . The gait aide use provident ranges as Nothing > Cane > crutch > walker up to 2 years
Secondary Evaluate the effectiveness of the robotic exoskeleton device at time of discharge through 2 years calculating Timed-up-and-Go at discharge, 3 months and 2 years after surgery up to 2 years
Secondary Evaluate the effectiveness of the robotic exoskeleton device at post operative follow up calculating device compliance (on/off) at 2 weeks and 3 months after surgery using a questionnaire 2 weeks and 3 months
Secondary Evaluate the effectiveness of the robotic exoskeleton device at post operative follow up To assess the effectiveness of device by calculating number of Falls at 2 weeks and 3 months using a questionnaire 2 weeks and 3 months
Secondary Evaluate the effectiveness of the robotic exoskeleton device at post operative follow up To assess the effectiveness of device by calculating Initial satisfaction with the device and satisfaction at 2 weeks and 3 months after surgery using a questionnaire. The scale ranges from:
Very satisfied Satisfied Neutral Not satisfied
2 weeks and 3 months
