Femoral Rotation Osteotomy in Patellofemoral Instability Surgery

Femoral anteversion is an important anatomic risk factor for patellofemoral instability. History and physical exam, in addition to diagnostic imaging, are all components of a full assessment to determine whether femoral anteversion is a significant contributor to a patient's patellofemoral symptomatology. When appropriate, derotational femoral osteotomies can address rotational malalignment and improve patient outcomes. While distal femoral osteotomies have most commonly been associated with femoral derotation, each level of correction has its own advantages and may be more suitable, depending on the location of greatest deformity.
