Brief Summary
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.

Outcome Measures
Primary Outcomes (2)
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 )
Using 50 pre-operative brain networks derived from advanced brain imaging will be assessed as predictors of postoperative patient satisfaction. Patient satisfaction measured by PROMIS questionnaire Preoperative resting-state fMRI brain connectivity will be assessed as a predictor of postoperative patient satisfaction measured using PROMIS questionnaires, which assess pain and function.
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)
Preoperative resting-state fMRI brain connectivity will be assessed as a predictor of postoperative patient satisfaction measured using the Oxford Knee Score, which assesses knee function and pain.
Time Frame: Preoperative (Baseline)
Secondary Outcomes (2)
Longitudinal Change in Brain Network Connectivity from Preoperative to 12 months after total knee arthroplasty
Pre-operative to 12-months Post-operative
Identification of Key Brain Network Nodes Associated with Postoperative Dissatisfaction after total knee arthroplasty
12 months postoperative
Study Arms (1)
fMRI Brain Scan
EXPERIMENTALInterventions
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.
