Bicruciate-stabilized total knee arthroplasty

Bicruciate-stabilized total knee arthroplasty increases patellar tendon angle in humans (15° ± 4° vs 9° ± 4°, mean difference -6° (95% CI -7° to -5°), p < 0.001).

“knees treated with the bicruciate-stabilized device had greater patellar tendon angles than those treated with the posterior-stabilized device (patellar tendon angle: 15° ± 4° versus 9° ± 4°; mean difference -6° [95% confidence interval (CI) -7° to -5°]; p < 0.001)”

Bicruciate-stabilized total knee arthroplasty has no effect on forgotten Joint score in humans (mean difference -1 (95% CI -5 to 2), p = 0.44).

“Likewise, the FJS did not differ between groups (51 ± 20 in the bicruciate-stabilized group versus 50 ± 22 in the posterior-stabilized group, mean difference -1 [95% CI -5 to 2]; p = 0.44)”

Bicruciate-stabilized total knee arthroplasty has no effect on knee Society Score in humans (mean difference -1 (95% CI -5 to 3), p = 0.57).

“There were no differences in 2-year PROs, including the KSS and WOMAC, in the bicruciate-stabilized and posterior-stabilized groups (KSS: 145 ± 23 versus 144 ± 24, mean difference -1 [95% CI -5 to 3]; p = 0.57”
