  1. Due to the ongoing character of the study, 26 subjects had not completed one-year period after THR at time of follow-up assessment. Thus only 131 out of 157 subjects from the baseline group were eligible for further investigations. Since 36 subjects dropped out, the analysis of responsiveness was performed in 95 patients
