A Quantitative Assessment of Early Mobility in Total Knee Replacement Patients Using Smart Activity Tracker

Overview

This study aims to evaluate the patients' mobility and quality of life prior to their total knee replacement surgery and their progress pre-operatively and 6 months post-operatively using the smart activity tracker. We hypothesize that mobility limitation presents a strong correlation with reduced quality of life.

The present study is to determine the effect of TKA based on their mobility and QOL pre and post surgery. The GPS and accelerometry-based tracker will be able to provide quantitative-based outcomes to indicate the physical activity of patients after TKR remains at or above pre-surgical levels. A total of 50 participants are to be enrolled in this cross-sectional study. Patients who will be required to undergo unilateral total knee replacement will be recruited when fulfilling the respective inclusion and exclusion criteria. The patients will undergo the standard consultations and rehabilitation pre - and post operative care, no changes to the treatment itself will be made. After recruitment and counseling by the surgeon for TKR, the patients will have pre-operative baseline clinical scores taken prior to surgery. They will subsequently have their TKR surgery. Post-operatively, they will be followed up prospectively at the clinics as well as Orthopaedics Diagnostic Centre. Their outcome will be evaluated using validated scoring system, Oxford Knee Score, SF-36, Knee Society Clinical Rating System, satisfaction questionnaire, as well as be provided with a GPS-activity tracker. 50 patients will be issued a Garmin GPS-activity tracker where they will be required to wear for 24 hours for 1 week, prior to each timepoint (pre-operatively and 6 months post surgery). The de-identified raw data gathered from the Garmin tracker will be collected by Curtin University for their analysis. The patients will undergo the standard consultations and rehabilitation pre - and postoperative care, no changes to the treatment itself will be made. Standard consultations/review by orthopaedic specialist * Pre-surgery * 6 months post surgery Standard Orthopaedic Diagnostic Center (ODC) data collection timepoints * Pre-surgrey * 6 months Standard rehabilitation care * Upon discharge * 2 - 3 weeks post discharge in outpatient services (OPS) On top of the standard consultations and rehabilitation pre - and postoperative care, the patients will be monitored on their normal lifestyle at home using a tracker worn on their wrists for 1 week, pre-operatively and 6 months post surgery.
