TL;DR: It is suggested that porous PEEK structures may provide a more favorable mechanical environment for bone formation and maintenance under spinal load magnitudes than currently available porous 3D-printed Ti, regardless of the level of bone ingrowth.

TL;DR: The results suggest that ACL reconstruction does not restore normal kinematics on the medial side of the knee, which may lead to early cartilage degeneration.

TL;DR: The long-term data suggest that skeletal changes that occur during long-duration spaceflight persist even after multiple years of recovery, which has important implications for the skeletal health of crew members, especially those who make repeat trips to space.

TL;DR: An improved mechanobiological model of bone morphogenesis and functional adaptation that includes the influences of periosteum tension and pressure on bone formation and resorption is developed and suggests that intracortical stresses dictate bone size, whereasPeriosteal pressures may work in combination with intracORTical stresses and other Mechanobiological factors in the development of local bone cross-sectional shapes.

TL;DR: A new image analysis technique showed that the strength of the femoral neck in 37 males varied significantly along the neck axis and that bending strength varied by a factor of up to 2.8 for different loading directions.
