Changes in Joint Gap Balances between Intra- and Postoperation in Total Knee Arthroplasty

Figure 2

Postoperative axial radiographs of the left distal femur. Patients sit on a table with their lower legs dependent and a 1.5 kg weight attached to the ankle on the treated side. The angle between the cut lines of the posterior femoral condyles and the proximal tibia represents the flexion gap balance (FGB).
