The objective of this study was to investigate if differences existed in the medio-lateral position of the patella between subjects with patellofemoral pain (PFP) and matched controls. Twelve female patients with PFP and 12 matched controls had their medio-lateral patella position assessed in 20 masculine of flexion. All subjects were found to have a laterally located patella although the mean lateral position for the individuals in the PFP group was more than for the control group.
Using this method of assessing patella position, the patella of individuals with PFP was significantly more laterally located than the patella of those in a matched control group.
