Defining the optimal cutting plane for derotational osteotomy at the distal femur for correction of torsion in cases of patellofemoral instability is still challenging. This preliminary study investigates changes of frontal alignment by a simplified trigonometrical model and demonstrates a surgical guidance technique with the use of femur cadavers.

Maintenance of optimal knee joint line orientation (KJLO) is important after high tibial osteotomy (HTO). No tools, however, are currently available that could predict the value of postoperative KJLO before surgery. First, this study sought to determine the effects of various preoperative anatomical alignment parameters to postoperative KJLO.

The valgus cut angle is the angle between mechanical and anatomical axis of the femur (FMA and FAA), and femoral condyle rotation is the angle between surgical trans-epicondylar axis and posterior condylar axis (sTEA and PCA). We used these indexes in total knee arthroplasty.
