Comparison of knee motion recovery on the basis of postoperative deep temperature change

	<2℃			>2℃
	admission	discharge	1-year	admission	discharge	1-year
Values are mean±SD. After deep tissue temperature change was calculated by subtracting the baseline temperature at admission from the highest postoperative one, 28 TKA patients were classified into two groups, <2℃ (n=6) and >2℃ (n=22). The data on the operated knee motion are shown. *P<0.05 vs the data at admission in the same group by paired t test.
