title: [Early clinical outcomes of fixed-bearing versus mobile-bearing total knee arthroplasty].
abstract: OBJECTIVE
  To compare the early clinical outcomes of primary total knee arthroplasty by a fixed-bearing versus mobile-bearing prosthesis.
  
  
  METHODS
  A total of 80 patients with osteoarthritis at our hospital from January 2008 to October 2008 were sequentially and randomly assigned into Group A (fixed-bearing prosthesis) (40 knees) and Group B (mobile-bearing prosthesis) (40 knees). And the data of the range of motion (ROM), Knee Society Score (KSS) and Western Ontario MacMaster (WOMAC) were collected at pre-operation and 6, 12 and 24 months post-operation respectively.
  
  
  RESULTS
  The P values were as follows: KSS: 0.754, 0.802, 0.561, 0.764; HSS (Hospital for Special Surgery): 0.737, 0.361, 0.254, 0.330; WOMAC (Western Ontario and McMaster Universities) osteoarthritis index: 0.976, 0.557, 0.946, 0.818; ROM follow-up: 0.519, 0.646, 0.175, 0.276. No significant differences were found in clinical outcomes between two groups.
  
  
  CONCLUSIONS
  The fixed-bearing and mobile-bearing prostheses show no difference in clinical outcomes.
