OBJECTIVES: To test the hypothesis that, at 0° and 20° of knee flexion, patellofemoral
contact area would be lower, while tibiofemoral rotation and patellofemoral malalignment …

Study Design Observational, cohort study. Objective To test the hypothesis that patellar
alignment and tibiofemoral rotation alignment explain unique portions of variance in …

Study Design Controlled laboratory study using a cross-sectional design. Objectives To
compare patellofemoral joint kinematics, femoral rotation, and patella rotation between …

Background: Patellofemoral pain syndrome is one of the most common knee problems and
may be related to abnormal patellar tracking. Our purpose was to compare, in vivo and …

PURPOSE: The role of frontal plane tibiofemoral alignment in subjects with patellofemoral
pain syndrome (PFPS) is controversial and rarely discussed in the literature. As well, little …

Background: Patellofemoral pain (PFP) is a prevalent disorder among female adolescents.
Overuse is frequently cited as the cause of pain for this population. What is currently unclear …

Study Design Case-control study of females with patellofemoral pain syndrome (PFPS) and
a control group. Objectives Three different approaches were used to examine the utility of a …

Background: Patellofemoral malalignment has been observed among people with
patellofemoral pain (PFP) and may be associated with the presence of imaging features of …

Fixed rotation of either the femur or tibia has a significant influence on the patellofemoral
joint contact areas and pressures. This is due to the anatomic asymmetry in the knee with …

PURPOSE AND METHOD: Lateral patellar malalignment and maltracking are commonly
believed to be associated with patellofemoral pain. In the current review, a computerized …
