Table 3.

Harris-Hip-Score (HHS), Hip Disability And Osteoarthritis Outcome Score (HOOS), EuroQol (EQ-5D) and Hospital for Special Surgery Total Hip Replacement Expectations (THR) Survey were obtained before and three years after THA according to the development of trochanteric pain syndrome. For quantitative data values are given as mean (SD = standard deviation).
