dc.description.abstractBackground: In total knee arthroplasty (TKA), the position of the patellar component can affect patellar tracking. However, the patellar component cannot always replicate the original high point of the patella because of anatomical variance. This study investigated whether altering the highest point of the patella can affect outcomes of primary TKA, especially in patients having a patella with a far-medialized median ridge.Methods: A retrospective review was performed for 177 knees (143 patients) treated with primary TKA between July 2011 and March 2014. Group 1 (34 knees) had the patellar component displaced over three millimeters from the median ridge, while Group 2 (143 knees) had the patellar component placed on the original median ridge position. The one-year follow-up outcomes were reviewed, including: patellar tilt angle, Knee Society Score, Feller Patellar Score, and modified Kujala Anterior Knee Pain Score.Results: Mean (+/- standard deviation) displacement of the patellar component in Group 1 was 3.97 +/- 0.97 mm lateral to the original position of the median ridge, with a significant decrease in lateral patellar tilt angle (P < 0.001). Lateral patellar tilt slimed a positive correlation with the medialization of the patellar component (P < 0.001, r = 0.401). Ability to rise from a chair was better in Group 1 (P = 0.025). There were no other between-group differences in other clinical outcomes.Conclusions: There should be no need for the patellar component to replicate the original highest point of the native patella in primary TKA.
