Abstract
knee prosthesis. If correct, it results into good functional outcome. The most important item in TKR is the alignment of total If incorrect, it results into abnormal wear, premature loosening and functional problems. Achievement of alignment of total knee prosthesis can be achieved conventionally without computer assisted navigation depending on preoperative, intraoperative and post operative evaluation of the patient. Preoperative:- 1)calculation of the valgus angle preoperative through CT scanogram for cutting of the distal femur perpendicular to the mechanical axis of the femur. 2)Evaluation of the mechanical axis through long leg standing X- ray. 3)Calculation of the ALDF and MPTA which can be calculated easily from CT scanogram.Intraoperative:- Cutting of the distal femur according the valgus angle calculated preoperatively and another important point in intraoperative checking that on calculation are proceeding in the correct manner, while in achieving good rotation of the femoral component we externally rotate the jig.
