- Abstract:
- The patella plays a critical role in enhancing power transmission within the extensor system of the lower extremity. Best possible functionality necessitates precise alignment of the patella within the trochlear groove. Patellofemoral stability is supported by ligaments, bony structures and neuromuscular factors. Instability in this system can lead to dislocations and impairments, particularly affecting young, active individuals. The complex etiology of patellofemoral instability complicates the in vivo assessment of confounding factors affecting joint stability. Recent advancements in computational models have facilitated the study of these factors through musculoskeletal simulations. Although the impact of several morphological parameters on the stability of the patellofemoral joint has been explored, substantial gaps remain in understanding the specific influences of altered gait patterns and other morphological variations, such as lower limb torsion. This thesis aims to address these gaps. Three studies were conducted to examine the impacts of (i) gait pattern, (ii) lower limb torsion and (iii) femoral derotation osteotomies on patellofemoral joint loading.
