@JOrthoPres.bsky.social reported in cementless TKA increased interference fit does not enhance primary stability, but more plasticity in bone, potentially more damage. Optimizing interference fit is crucial to balance fixation and minimize damage buff.ly/Qvoo2iu

CRISPR helps to show why a boy felt no pain Mutation in an enzyme leads to resistance to chronic and acute pain, according to research in mice.

The study of a boy who was unable to feel pain could lead to innovative therapies for chronic pain

Alignment of the femur and tibia before and after personalization. This figure presents how the Torsion Tool changes the shape and alignment of the femur and tibia (red) compared to the generic torsion model (green). The left side represents the personalization for the femoral torsion model, while the right side represents the personalization for the torsion-informed model. The personalized models represent one participant with a 36° femoral version and 38° tibial torsion.

What is the impact of femoral and tibial torsion on patellofemoral loading in individuals with patellofemoral instability? Find out in this recent paper by Bernhard Guggenberger & coauthors: onlinelibrary.wiley.com/doi/10.1002/...
