Fig. 3From: Evaluation of the flexion gap with a distal femoral trial component in posterior-stabilized total knee arthroplastyModified gap technique adjusting the gap size. First, the rotation of the osteotomy line (dotted line) was determined. Dotted line: osteotomy line was determined on the basis of the posterior reference so that the flexion gap is square. Next, the amount of posterior condylar osteotomy was determined. Solid line: actual osteotomy line was determined so that the flexion gap is equal to the extension gap.
