AB  - BACKGROUND: Current literature suggests that 8%-35% of patients undergoing total 
      hip arthroplasty (THA) undergo a subsequent contralateral THA. This study aims to 
      determine if functional outcomes after primary THA predict outcomes in the 
      subsequent primary THA of the contralateral side. METHODS: A retrospective cohort 
      of patients undergoing staged bilateral primary THA was reviewed. The Oxford Hip 
      Score (OHS) was utilized as the functional outcome measurement tool and was 
      assessed preoperatively and at one year postoperatively. The minimal clinically 
      important difference (MCID) was assessed. Based on the first-side THA one-year 
      outcomes, the odds of maintaining an MCID, or not, for the second-side THA were 
      determined. RESULTS: The study cohort consisted of 551 patients and 1102 primary 
      THAs. The average postoperative OHSs were similar after the first and second THA. 
      Patients achieving the MCID with the first-side surgery were 2.6 times (95% 
      confidence interval 1.0 to 6.64, P = .04) more likely to achieve the MCID for the 
      second-side surgery than patients failing to reach the MCID for their first-side 
      surgery. After the first THA, 29 (5.3%) patients failed to reach the predefined 
      MCID for the OHS compared with 54 (9.8%) patients undergoing their second THA 
      (odds ratio: 1.96 [95% confidence interval: 1.23 to 3.1], chi(2) = 8.14, P = .005). 
      CONCLUSIONS: Functional outcomes after the first THA are predictive of functional 
      outcomes of the second THA. Patients are more likely to achieve a clinically 
      significant improvement after their first THA related to higher preoperative OHSs 
      before the second THA.
