The patellofemoral joint: from dysplasia to dislocation

[摘要] Trochlear dysplasia is defined as a geometrical abnormality of the shape and depth of the trochlear groove mainly at its proximal part, where the patella engages into the trochlea. This represents the main feature of the wider and less codified concept of patellofemoral dysplasia, together with patellar height abnormalities, axial and rotational malalignments and soft-tissue imbalances. In this regard, a strict correlation of proximal femoral anatomy and trochlear geometry have been reported, confirming the possible multi-directional factors involved in this dysplastic condition.
