Brief Summary
This study will use a special type of x-ray called radiostereometric analysis (RSA) imaging to determine whether patient-specific instrumentation for total knee arthroplasty (replacement) has an effect on implant loosening compared to conventional instrumentation. Secondary objectives will include assessment of post-operative implant alignment, patient satisfaction, operative time and surgical instrument use, cost, and environmental impact.
