Advantages and Disadvantages of the Femoral Sulcus Deepening Trochleoplasty of Lyon

Advantages
  • -

    This technique has shown to be the most effective in reducing recurrence.

  • -

    The surgeon has a complete view of the trochlear surface and this makes it easier to modify the shape in very dysplastic trochlae.

  • -

    The same anterior approach is used for MPFL reconstruction.

  • -

    Removing the undersurface strip of cortex with an oscillating saw is less time-consuming than performing it entirely with a burr.

  • -

    Leaving 5 mm of subchondral bone below the articular surface makes it a less-aggressive procedure relative to the cartilage layer.

  • -

    Performing 3 osteotomies enables a better reshaping of the trochlear groove.

Disadvantages
  • -

    The described technique is not minimally invasive, as it requires a 5- to 10-cm incision.

  • -

    Osteochondral flaps with a thickness of 5 mm might be more difficult to mold.

  • -

    A split of the trochlear cartilage is required to create the new groove.

  • -

    The notch anchor required articular cartilage violation.
