Brain scans to find links between brain activity and knee replacement outcomes
Official title: Brain Network-based Precision Medicine to Predict Dissatisfaction Following Total Knee Arthroplasty
Run by Ottawa Hospital Research Institute · NCT07464080 · Data updated 2026-11-12
This study uses brain MRI before and after knee replacement to see if patterns of brain activity can predict which patients will be satisfied with their surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) scheduled for a primary TKA for osteoarthritis, inflammatory arthritis, or osteonecrosis who can undergo MRI, speak English or French (or have an approved translator), and do not have major neurological disease, cognitive impairment, revision/bilateral TKA, or chronic opioid use.
✕Probably not a fit
People with major neurological disorders, dementia or cognitive impairment, revision or bilateral TKA, chronic opioid use, or who cannot attend scans at the study site are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The study uses functional MRI to map brain network activity before and after primary total knee arthroplasty (TKA). Researchers will compare pre- and postoperative brain connectivity and link those changes to patient-reported pain, function, and satisfaction. The aim is to identify brain-based markers that could predict who will remain satisfied or dissatisfied after surgery. The work is performed at The Ottawa Hospital and excludes people with major neurological disorders, cognitive impairment, revision or bilateral TKA, or chronic opioid use.
Why it matters
Potential benefit: If successful, the approach could help clinicians predict which patients are at higher risk of poor satisfaction after knee replacement so care can be personalized.
How similar studies have gone: Previous research has linked brain connectivity patterns to chronic pain and some postoperative outcomes, but using fMRI to predict patient satisfaction after TKA is a relatively new approach and not yet proven.
