Fig. 2From: Large flexion contracture angle predicts tight extension gap during navigational posterior stabilized-type total knee arthroplasty with the pre-cut technique: a retrospective studyGap values of the EG and FG pre- and post-PMVC in group T. The value of the EG in group T increased significantly after the PMVC (from 3.9 mm to 7.6 mm). However, the increase in FG was not significant (from 7.6 mm to 8.1 mm).
