a
There was no significant difference (NS) in the side-to-side knee stability between the 2 groups.
b
There was a significant difference in the pivot shift test result between the 2 groups.
c
There was a significant difference between the “well” and “less” preserved groups.
d
There was a significant difference between the “more than 50%” and “resected” groups.
e
There was a significant correlation among the 3 groups (Spearman ranked correlation analysis).
