Patellofemoral pain (PFP) syndrome is one of the most common problems of the knee. Typical symptoms are anterior knee pain, exacerbated by activities such as stair descent, prolonged sitting and squatting. Patellar maltracking is generally accepted as a leading causes of PFP. However, effective intervention has been hampered because the mechanical factors related to PFP are poorly understood. Thus, the primary objective of this study was to explore the possibility that numerous maltracking patterns exists within the umbrella term of maltracking in PFP. As an adjunct to this, the correlation between bone shape and PF kinematic was investigated.
