Biomechanical comparison of patellar cementing techniques in total knee arthroplasty: a biomechanical study

The mean peak stress pressure of a total of 30 test specimens was 1305.86 (± 24.72) N (Newton) and these values were determined as 1013.00 (± 24.72), 1334.60 (± 37.17) and 1570.00 (± 26.56) N for group 1, group 2 and group 3, respectively (p < 0.001). A statistically significant difference was found in the multiple comparisons of all groups with each other and fixation of group 3 was found to be better than group 1 and 2 (p < 0.001). CONCLUSION: The modified cementing technique demonstrated superior biomechanical fixation strength compared to conventional methods in this in vitro study. This low-cost and easily applicable technique may help reduce patellar component-related complications and warrants further evaluation in clinical settings.
