Does preclinical analysis based on static loading underestimate post-surgery stem micromotion in THA as opposed to dynamic gait loading?

Finite Element Models to Predict the Risk of Aseptic Loosening in Cementless Femoral Stems: A Literature Review

“…To clarify the last exclusion criterion, it is important to note that there is a significant body of literature that focuses on the mechanical behaviour of primary stability, which is an important risk factor for the AL of cementless hip implants. And evidence was found that early peri-implant bone healing immediately after implantation and the consequent mechanical remodelling at the bone-implant interface are essential for secondary implant stability [45,46]. However, it is the secondary stability that directly leads to the occurrence of AL.…”
