Key: An empty cell indicates that the particular knee rating at the top of the column was not signficantly affected by meniscal and articular surface conditions.
light shaded cells indicate result was counter-intuitive to initial hypothesis.
dark shaded cell indicates a non-significant p value, even though the Odds Ratio does not cross 1.00
