Role of Femoral Anatomical Mechanical Angle in Getting Alignment in Total Knee Arthroplasty

In the present study, we had pre-operative determination of the femoral anatomical mechanical angle which was accomplished using anteroposterior weight-bearing hip-to-ankle radiographs. Intraoperative distal femur variable valgus cut was taken depending upon preoperative FAMA. We accessed pre and post-operative mechanical axis of the lower limb on long-length X-ray films and evaluation of functional outcome.

To study pre and post-operative FAMA and lower limb alignment in post-operative long leg standing radiograph.

12 months.

Prospective study.

52 Patients.

The study findings recommended that all patients for the primary total knee arthroplasty should be evaluated with long leg weight-bearing radiograph preoperatively to find lower limb alignment and FAMA. Intraoperatively, distal femur valgus cut should be taken variable depending upon preoperatively evaluated FAMA.
