Does external rotation of the femoral component decrease patellofemoral contact stress in total knee arthroplasty?
Regarding the alignment of the femoral component, only the rotational alignment of the femoral component was correlated with PF contact stress. PF contact stress decreased more as the femoral component rotated more externally.
hCGbeta is a diagnostically sensitive marker for testicular cancer. In patients with seminomatous testicular cancer, hCGbeta is superior to hCG, and in some NSGCT patients it provides additional information.
