AB  - BACKGROUND: The bicruciate-stabilized (BCS) knee arthroplasty was developed to 
      replicate normal knee kinematics. We examined the hypothesis that patients with 
      osteoarthritis requiring total knee arthroplasty (TKA) will have better 
      functional outcome and satisfaction with the BCS implant compared with an 
      established posterior cruciate-stabilized implant. METHODS: This multicenter, 
      randomized, controlled trial compared the clinical outcomes of a BCS implant 
      against an established posterior cruciate-stabilized implant with 2-year 
      follow-up. Of the patients awaiting primary knee arthroplasty for osteoarthritis, 
      228 were randomized to receive either a posterior-stabilized or BCS implant. 
      Primary outcomes were knee flexion and Oxford Knee Score. Secondary outcomes were 
      rate of complications and adverse events (AEs). Tertiary outcomes included Knee 
      Society Score, University of California, Los Angeles, activity score, Patella 
      scores, EQ-5D, 6-minute walk time, and patient satisfaction. RESULTS: Complete 
      data were recorded for 98 posterior-stabilized implants and 97 BCS implants. 
      Twelve patients had bilateral knee implants. There was no difference between the 
      groups for any of the measures at either 1 or 2 years. At 2 years, knee flexion 
      was 119 +/- 0.16 and 120 +/- 1.21 degrees for the posterior-stabilized and BCS 
      implants, respectively, (mean, standard error, P = .538) and Oxford Knee Scores 
      were 40.4 +/- 0.69 and 40.0 +/- 0.67 (P = .828), respectively. There were similar 
      device-related AEs and revisions in each group (AEs 18 vs 22; P = .732; revisions 
      3 vs 4; P = .618). CONCLUSION: There was no evidence of clinical superiority of 
      one implant over the other at 2 years.
