  1. TJA total joint arthroplasty
  2. aData are presented as the mean ± standard deviation
  3. bData are presented as the number (percentage) of patients
  4. cP value was calculated by the independent t test
  5. dP value was calculated by the chi-square test
  6. eP value was calculated by the Mann-Whitney U test. P < 0.05 indicates a significant difference between groups
