Table 5.
Pearson (linear) correlation coefficients for linear associations with lateral release.
| Risk factor | r | P value |
|---|---|---|
| Age at surgery | 0.0043 | .9537 |
| Millimeter to midline from mechanical axis | 0.5457 | .0000 |
| Anatomic tibiofemoral angle | 0.5382 | .0000 |
| Mechanical hip-knee-ankle angle | 0.5638 | .0000 |
| Preoperative mechanical femoral condylar angle | 0.2673 | .0003 |
| Preoperative anatomic femoral condylar angle | 0.0993 | .1824 |
| Preoperative mechanical tibial condylar angle | 0.2961 | .0000 |
| Preoperative anatomic tibial condylar angle | 0.3890 | .0000 |
| Preoperative medial joint space on standing films | 0.3391 | .0000 |
| Preoperative medial joint space adjusted for magnification | 0.3893 | .0005 |
| Postoperative mechanical hip-knee-ankle angle | −0.2726 | .0003 |
| Postoperative mechanical femoral condylar angle | −0.3158 | .0000 |
| Postoperative mechanical tibial condylar angle | −0.1209 | .1153 |
Note: This table provides the pairwise Pearson correlation coefficient (r) and corresponding P value for testing whether the correlation coefficient is different from 0 vs not. For example, from row 3, we conclude that the lateral release and anatomic tibiofemoral angle are positively correlated or associated with r = 0.54 (P < .0001).
