Study 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.
Primary Outcome
Post-resection symmetry of the patella was independently assessed by a resident or fellow who was not involved in the resection. This was evaluated by dividing the patella into four equal quadrants and measuring the thickness in the center of each quadrant using a ring tipped or "C"-shaped caliper. The difference between the thickest and thinnest measurements of the patella was reported as the value of asymmetry.
Interventions
- PROCEDURE Cutting Guide Technique
- PROCEDURE Haptic Feedback Technique
