This case-control study showed that there are differences at the initial visit between a nonprogressive and a progressive group of patients with adolescent idiopathic scoliosis (AIS). Progressive AIS presented hypokyphosis, higher values for rotational parameters (plane of maximal curvature, torsion, and apical intervertebral rotation) and lower values for local and regional slenderness.

Both surgical techniques for anatomical posterolateral corner reconstruction showed good results in the static laxity tests. The anatomical reconstruction of all structures, including the popliteus tendon, resulted in an abnormal internal tibial rotation during dynamic testing.
