This review describes anatomic features of the patellofemoral joint that relate to the stability
and function of the joint. The role of the geometry of the articular surfaces, particularly the …

This review presents objective data, as far as possible, about the current understanding of
the biomechanics of the patellofemoral joint as it pertains to the management of …

Normal function of the patellofemoral joint is maintained by a complex interaction between
soft tissues and articular surfaces. No quantitative data have been found on the relative …

Background: Recurrent patellar instability is a common problem after dislocation. The medial
patellofemoral ligament (MPFL) contributes 40–80% of the total medial restraining forces …

Background Reconstruction of the medial patellofemoral ligament has been proven to
restore stability in patients with lateral patellar instability. No study to date has examined the …

Anterior knee pain is a common symptom, which may have a large variety of causes
including patellofemoral pathologies. Patellofemoral maltracking refers to dynamic …

Patellofemoral pain is the most common knee problem encountered by primary care
physicians. A complete understanding of the etiology, pathophysiology, and optimal …

Background: Trochlear dysplasia is a known risk factor for patellar instability. Multiple
radiographic measurements exist to assess trochlear morphology, but the optimal …

Background: Delayed onset of vastus medialis (VM) activity compared with vastus lateralis
activity is a reported cause for patellofemoral pain. The delayed onset of VM activity in …

Patellofemoral (PF) pain is a common ailment of the lower extremity. A theorized cause for
pain is patellar maltracking due to vasti muscle activation imbalance, represented as large …
