Patella Resection In Total Knee Arthroplasty: An Analytical Comparison Of Three Techniques, Kelsey Cushway

Medical Engineering Theses

Patella resection, as a routine component of TKA, can be both difficult to plan and difficult to execute. The primary purpose of this study was to evaluate the repeatability of three unique patellar resection techniques used in total knee arthroplasty. The secondary purpose of this study was to establish whether different surgical techniques were able to reproduce preoperative plans made by each surgeon. We used radiographic measurements to evaluate patellar thickness and patellar cut angle preoperatively and postoperatively. Three techniques (45 cases in total) were evaluated, revealing qualitative differences between surgical techniques and significant quantitative differences between average patellar thickness …
