Official title
Brain Network-based Precision Medicine to Predict Dissatisfaction Following Total Knee Arthroplasty
Overview
Knee replacement surgery is a common and effective treatment for pain and mobility loss, yet up to 1 in 5 patients remain dissatisfied after surgery due to ongoing pain or difficulty with daily activities. Currently, clinicians cannot reliably predict which patients will experience these challenges. This study uses MRI scan of the brain to investigate whether specific patterns of brain activity can predict patient satisfaction after total knee arthroplasty (TKA). By comparing brain networks before surgery and afterward, and linking these changes to patient-reported pain and function, we aim to identify brain-based markers that can help predict outcomes, to improve satisfaction after knee replacement surgery.
Interventions
- Procedure fMRI Brain Scan
A research brain MRI scan will be performed on a 3T scanner. The MRI session will take approximately 50 minutes of scanning time. The MRI scan will be repeated again 2 months after surgery.
Primary outcome measures
- Preoperative Resting-State fMRI Brain connectivity as a Predictor of Patient operative Satisfaction after Total Knee Arthroplasty measured by Patient-Reported Outcomes Measurement Information System (PROMIS ) [Time frame: Preoperative (Baseline)]
- Preoperative Resting-State fMRI Brain connectivity as a Predictor of Patient operative Satisfaction after Total Knee Arthroplasty measured by Oxford Knee Score (OKS) [Time frame: Time Frame: Preoperative (Baseline)]
Secondary outcome measures (2)
- Longitudinal Change in Brain Network Connectivity from Preoperative to 12 months after total knee arthroplasty [Time frame: Pre-operative to 12-months Post-operative]
- Identification of Key Brain Network Nodes Associated with Postoperative Dissatisfaction after total knee arthroplasty [Time frame: 12 months postoperative]
