Figures & data
Figure 1. The joint component gap was measured manually as guided by a navigation system. Photograph (A) and screen shot (B) show varus stress at 120°. Photograph (C) and screen shot (D) show valgus stress at 120°. Screen shots show 1° varus in varus stress (B) and 3° valgus in valgus stress (D); thus medio-lateral laxity (soft tissue balance) was calculated as 4°.
