Factors associated with physical activity following total knee arthroplasty for knee osteoarthritis: a longitudinal study

Table 2 Physical activity assessed preoperatively and 6 months postoperatively

Assessments	Preoperative	6 months postoperative	p-value	Effect size
Average daily step count (steps/day)	4717.7 ± 2533.1	5353.8 ± 2706.9	< 0.001	0.433
Time spent in MVPA (min/day)	4.5 ± 5.6	7.9 ± 7.9	< 0.001	0.665

MVPA, moderate-to-vigorous-intensity physical activity
Physical activity was analyzed using the Wilcoxon signed-rank test
Note: Data are expressed as means ± standard deviations. Statistically significant p values (p < 0.05) are shown in bold font. Effect size: <0.1 = trivial effect, 0.1–0.3 = small effect, 0.3–0.5 = medium effect; and > 0.5 = large effect
