  1. aThe international Hip Outcome Tool (12 items) – Greek version
  2. bAs external criterion for examined the ability of iHOT12-Gr to distinguish subgroups of patients formed on the basis of their functional status, the cut-off point (53 points) of the Lower Extremity Functional Scale – Greek version was used. The independent samples t-test was used for the statistical analysis
  3. cThe values are expressed as Mean ± Standard deviation (SD)
