TABLE 3.
Significant (P < .05) Associations With the Risk of CACL Injury From the Univariate Cox Regression Analysis
| HR | 95% CI | P Value | |
|---|---|---|---|
| Agea | 1.70 | 1.17–2.63 | .004 |
| Hours/week of sport participationa | 1.19 | 1.00–1.45 | .048 |
| Hip anteversionb | 2.38 | 1.16–5.14 | .017 |
| Anterior knee stiffnessa | 2.37 | 1.03–6.60 | .042 |
a
Hazard ratios (HRs) with corresponding 95% CIs indicating the increase in risk of contralateral anterior cruciate ligament (CACL) injury per 1-year decrease in age, 1 hour per week decrease in sport participation, or 1 SD decrease in anterior stiffness of the knee.
b
HRs with corresponding 95% CIs indicating the increase in risk of CACL injury per 1 SD increase of the variable.
