Prospective evaluation of patient compliance and prescribed home exercise program using MotionSense wearable system during recovery from primary total knee arthroplasty.
During the proposed study, the MotionSense wearable system will be used by patients undergoing total knee arthroplasty (TKA) surgery leading up to and after their surgery. The patients will be using the system to monitor their recovery during daily activities, log daily pain scores and patient reported outcomes while also supporting their prescribed home exercise program. Each patient will thereby participate in outpatient physiotherapy in line with their current standard of care, while the physiotherapist will leverage the opportunities of the presented platform to give the patient personalized reminders for their patient-specific home exercise program. The surgeon / research nurse will additionally be able to monitor the patients recovery remotely as the sensor / app data is shared to the OrthoLogIQ platform.

Correlate Functional and Patient Reported Outcome Metrics
Spearman correlation of mean step count to Knee Injury and Osteoarthritis Outcome Score (KOOS) patient questionnaire. The Statistical Spearman correlation coefficient evaluates relationships between variables. The Spearman correlation coefficient is used to evaluate the relationship of the mean step count to the Knee Injury and Osteoarthritis Outcome Score (KOOS) patient questionnaire. The KOOS consists of 5 subscales: Pain, other symptoms, function in daily living (ADL), function in sport and recreation and knee related quality of life (QOL). The Spearman Correlation coefficients range from -1to 1. If r = 0, there is no linear relationship between the variables. If r=+1, there is a strong direct relationship. If r = -1, there is a strong inverse relationship.
Time frame: 2 weeks, 6 weeks, 90 days postoperative

Establish Normative Recovery Data for the Primary Outcome Metrics Captured by the MotionSense System: Daily VAS Pain Scores
Visual Analog Scale (VAS) pain scores while wearing MotionSense from 30 days preoperative to 90 days postoperative The VAS pain score is a patient questionnaire to assess the subjective pain intensity. The VAS is a horizontal line ranging from 0 to 10, where 0 represents no pain and 10 represents the worst possible pain.
Time frame: 30 days preoperative to 90 days postoperative
Establish Normative Recovery Data for the Primary Outcome Metrics Captured by the MotionSense System: Daily Steps
Daily steps while wearing MotionSense from 30 days preoperative to 90 days postoperative

Scores while wearing MotionSense from 30 days preoperative to 90 days postoperative Range of Motion (ROM) for the knee refers to the degree of movement that can be achieved at the knee joint. It describes the arc or extent of motion from full extension (straightening) to full flexion (bending) in degrees.
