Abstract:
[Objective]To measure the verus inclination of the proximal tibial of young Chinese through radiographs and determine how many degrees should the femoral prothesis be externally rotationed during total knee arthroplasty(TKA).[Method]Standardized anteroposterior radiographs of the entire lower legs of 200 volunteers' were taken. Two angles were measured as followes:Angle PT: angle between tibial articular margins and a line perpendicular to the tibial mechanical axis;Angle FT:angle between the transcondylar tangent anda line perpendicular to the tibial mechanical axis. [Result]Angle PT has a mean value of 4.06? and Angle FT is 5.00?. [Conclusion]When the posterior condylar axis is used during TKA for Chinese, the femoral prothesis should be externally rotationed 5.00? to get the optimum rotational orientation.
