The influence of different walking strategies on patellofemoral and tibiofemoral contact forces in individuals with patellofemoral instability

Patellofemoral instability (PFI) and associated patella dislocations are common knee injuries in adolescents [1] and are affected by various morphologic factors [2]. Recent studies have shown how morphologic factors influence patellofemoral stability and knee loading [3,4]. However, these studies were based on the walking pattern of a single healthy person and therefore did not consider the diversity of gait patterns in individuals with PFI. Depending on the sagittal knee moment, Clark et al. [5] showed two different walking strategies, that could influence the knee loading.
