Table 2.

Mean±standard deviation anterior displacement (mm) for the injured and the noninjured knees at the three different time-points of Rolimeter readings (n=15)

Time-points	Injured knee	Noninjured knee	Side-to-side difference	Two-way ANOVA	F statistic	P-value	ES
Baseline	9.3±2.3	6.7±1.8	2.6±2.5	Condition effect*	F (1,14)=16.9	0.001	0.55
Midpoint	9.7±2.2	6.9±1.8	2.8±2.4	Time-point effect	F (2,28)=1.7	0.208	0.11
Endpoint	9.5±2.7	6.9±1.8	2.7±2.9	Interaction effect	F (2,28)=0.3	0.775	0.02

Side-to-side difference, defined as the difference between the injured and the noninjured knee. F, P-value, and effect size (ES) were obtained by a two-way analysis of variance (ANOVA) (2×3: knee conditions vs. time-points).

Significant two-way ANOVA effect for condition* (i.e., injured versus noninjured knee).
