    Fluoroscopic imaging provides high temporal resolution for in vivo assessment of joint kinematics, crucial for orthopedic analysis.

  • 2

    Accurate 2D/3D registration aligns fluoroscopic images with CT-derived models, essential for reconstructing knee joint kinematics.

  • 3

    Traditional registration methods often struggle with accuracy due to non-convex optimization landscapes in low-quality fluoroscopic images.

  • 4

    The proposed pose-aware deep perceptual similarity metric utilizes contrastive learning to improve registration accuracy and convergence.

  • 5

    This new metric enhances the optimization landscape, making it more robust against pose variations and imaging noise.
