Abstract
Purpose
To compare the clinical and radiological results between patellar resurfacing, group and patellar retention group in total knee arthroplasty.
Materials and Methods
Of the 74 patients who underwent total knee arthroplasty on due to knee osteoarthritis since March 1996, and followed-up for at least for 5 years, there were 42 and 32 cases in the patellar retention and patellar resurfacing groups respectively. These subjects were evaluated preoperatively and at 1 and 5 years postoperatively using the pain score, Hospital for Special Surgery (HSS) knee score, walking and stair-climbing in knee function score and radiological analysis. The radiological evaluation was achieved by measuring the patellar tilt angle and displacement with a 45°merchant view. The results were analyzed using the student's t-test.
