FP2.4 Spinopelvic characteristics as a risk factor for development of Cam morphology in adolescence: a 2 year follow-up study in a cohort of elite football players Open
Background: Cam morphology of the proximal femur leads to a loss in the naturally concave head-neck junction. Its presence has been linked to the development of femoroacetabular Impingement, intra-articular damage, and ultimately the early…

Correlation between tibial and femoral bone and cartilage changes in end-stage knee osteoarthritis Open
Knee osteoarthritis is a whole joint disease highlighting the coupling of cartilage and bone adaptations. However, the structural properties of the subchondral bone plate (SBP) and underlying subchondral trabecular bone (STB) in the femora…

Reduced intra-tendinous sliding in Achilles tendinopathy during active plantarflexion regardless of horizontal foot position Open
The Achilles tendon consists of three subtendons with the ability to slide relative to each other. As optimal intra-tendinous sliding is thought to reduce the overall stress in the tendon, alterations in sliding behavior could potentially …
