AB  - BACKGROUND: We aimed to investigate the influence of preoperative radiological 
      severity and symptom duration of hip osteoarthritis (OA) on the postoperative 
      functional outcome, quality of life, as well as abductor muscle strength after 
      total hip arthroplasty (THA). METHODS: In this prospective cohort study, we 
      studied 250 patients. Preoperatively, we evaluated the function with the Western 
      Ontario and McMaster Universities Osteoarthritis (WOMAC) index and quality of 
      life with euroqol-5D (EQ-5D). At 1 year after THA, the same scores and also hip 
      abductor muscle strength were measured in 222 patients. We divided the cohort 
      twice, first according to the radiological OA severity [Kellgren-Lawrence 
      classification (KL)] and then according to the OA symptom duration. We 
      investigated whether the preoperative KL class and symptom duration influenced 
      the 1-year WOMAC (primary outcome measure) or EQ-5D and abductor muscle strength 
      (secondary outcome measures). RESULTS: The crude results showed that KL class and 
      symptom duration had no influence (P = .90 and P = .20, respectively) on the 
      1-year WOMAC. Younger age, male gender, and lower body mass index were associated 
      with a better function. Regarding 1-year EQ-5D, the crude results showed that 
      body mass index and KL class had no influence (P = .83 and P = .39, 
      respectively). The adjusted results showed that only age and gender influenced 
      the postoperative EQ-5D. No influence of the tested factors was found on the 
      1-year abductor muscle strength. CONCLUSION: Preoperative radiological OA 
      severity and symptom duration had no influence on the outcome of THA and should 
      probably not affect the decision about timing the operative intervention.
