    The two special modules « Patellofemoral Measurements » and « Corrective Osteotomy », all neccesary measurements and preoperative planning functions are now availiable for all Sports Medicine Practitioners. Both can be measured quickly at the tibiofemoral  and patellofemoral joint. A therapy by means of an osteotomy can therefore be easily planned and transferd into the OR.

    Patellofemoral Measurements
    In the patellofemoral joint pathologies include Patellar maltracking as well as Patellar dislocation. Malpositions can be easily identified with the availiable portfolio of measurements listed below.

    Measurement Options:

    • TT-TG distance
    • TT-PCL distance (CT/MRI)
    • Sulcus angle
    • Trochlear depth
    • Measurement of leg axis
    • Determination of patella angle
    • Definition of patella height (Insall-Salvati, Caton-Deschamps)
    • Femoral torsion (according to Waidelich and Schneider)
    • Tibial torsion (according to Waidelich and Jend)
    • Trochlear classification according to Dejour

    Corrective Osteotomy

    A corrective osteotomy mainly addresses pathologies inside the patellofemoral joint, which are often due to patellar maltracking and malrotation of the distal femur. Maltracking for example can be corrected with a derotational osteotomy.

    Measurement and planning options:

    • Measurement of the leg axes including femoral and tibial torsion
    • Measurement of the tibial posterior slope
    • Planning a HTO or a DFO
    • Planning a double level osteotomy
    • Planning a derotation osteotomy
    • Measurements and planning in 2D and 3D
    • Imaging: CT, MRI, CBCT, X-ray
