title: [One-stage bilateral total hip arthroplasty: a systematic review and meta-analysis].
abstract: OBJECTIVE
  To investigate whether bilateral total hip arthroplasty (THA) performed in one session is a safe procedure.
  
  
  METHODS
  Systematic review.
  
  
  METHODS
  In a literature search, 1460 studies were found of which 5 prospective in nature and which met our inclusion criteria. The patient data from these studies were pooled for meta-analysis. Data from 579 patients could be pooled for the two-session bilateral THA group and data from 334 patients for the one-session THA group.
  
  
  RESULTS
  After this pooling of data, no difference in major complications was found (odds ratio: 0.72; 95%-CI: 0.45-1.15). Minor complications occurred more often in the one-session group (odds ratio: 0.50; 95%-CI: 0.32-0.78). Intra-operative blood loss was less in the one-session group (121.7 ml; 95%-CI: 51.6-191.9), whilst the number of transfusions was greater in this group than in the two-session group (-0.5 units; 95%-CI: -0.74--0.20). Duration of the surgical procedure was not influenced by the choice for one or two sessions (difference: 6.0 minutes; 95%-CI: -2.4-14.4). Length of hospital stay was significantly shorter in the one-session group (3.2 days; 95%-CI: 3.0-3.7).
  
  
  CONCLUSIONS
  We conclude that one-session bilateral THA appears to be a safe procedure in selected patients.
