Comparison of demographic data between the two groups classified on the basis of postoperative deep temperature change
| deep temperature change | <2℃ | >2℃ | P |
|---|---|---|---|
| Values are expressed as mean±SD. After deep 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. After Shapiro-Wilk test of normality, data were compared by t test (*) and Mann-Whitney test (**) for parametric and nonparametric tests, respectively. BMI: body mass index, ROM: range of motion, CRP: C-reactive protein. | |||
