Bidirectional joint line convergence angle changes and their preoperative predictors 12 months after medial closing-wedge distal femoral osteotomy for valgus knees: A single-centre exploratory study. [PDF]

J Exp Orthop
In 62 valgus knees from 54 patients, signed joint line convergence angle changes 12 months after medial closing‐wedge distal femoral osteotomy showed substantial between‐knee variability despite a small mean change. The prediction model remains exploratory and should not be used to determine patient‐specific correction angles.
