Summary
This research was performed to determine which of the three techniques used by knee surgeons at the Mayo Clinic was the most accurate at the surgical removal (resection) of the knee-cap (patella) in a symmetric fashion during total knee replacement (arthroplasty). Although all three techniques are known to be effective, the three techniques had never been compared to one another to determine if one was more effective than the others at resecting the patella.
