Official title
Total Knee Replacement Using Standard Knee Cutting Guides vs Otismed MRI Generated Cutting Guide
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Patients are referred to the VA orthopedic surgical clinic because of osteoarthritis and are requesting consideration for a total knee replacement. Those who qualify for the knee replacement are informed about the study. Those who consent to participate are randomly assigned to either the standard cutting guide or to the new method which is a MRI generated cutting guide called Otismed. All patients have an MRI so both groups will be unaware of which surgical technique is used. All patients receive the usual pre-op care and same type of replacement knee. Follow-up research visits are scheduled at 4 weeks, 3 and 6 months, and 1 and 2 years. Patients will be informed of which surgical technique they were randomized to at the conclusion of the study.
