The shape and orientation of the trochlea run more parallel to the posterior condylar line than generally believed

ConclusionThe ATL was on average 4.3 ° (SD 3.3°) internally rotated relative to the sTEA and 2.1° (SD 3.0°) internally rotated relative to the PCL. The ATL is more externally orientated in varus knees and more internally rotated in valgus knees. The trochlear groove is lateralised by only 2.2 mm when the femoral component is exter nally rotated.Level of evidenceIII.
