Cognition Clinical Trial
Official title:
Cognition Following Computer Assisted Total Knee Arthroplasty: A Prospective Cohort Study
A significant number of patients experience postoperative cognitive changes following total joint arthroplasty. Among other causes, the mental status change may be the result of fat and bone marrow debris embolization. We hypothesized that the use of computer assisted total knee arthroplasty, which does not utilize intramedullary alignment rods, would produce less fat and bone marrow debris embolization and, hence, fewer mental status changes.
Inclusion criteria
- Primary, cemented knee arthroplasty
- Unilateral or bilateral TKA
Exclusion criteria
- Patient is unable to speak English
- Unable to read and write
- Patient with history of psychiatric disorders (Depression, Schizophrenia, anxiety,
bipolar dis.)
- Patients with history of IV drug abuse
- Previous history of dementia
- Patients on mental status changing medications
