title: Clinical pathways in total knee arthroplasty: a New Zealand experience.
abstract: OBJECTIVE
  To ascertain the effects of a clinical pathway in our institution.
  
  
  METHODS
  This retrospective and comparative study was performed on all patients undergoing total knee arthroplasty over a 5-year period. This period covered the 30 months prior to the introduction of the pathway (group 1), and the 30 months following its introduction (group 2).
  
  
  RESULTS
  There was a significant reduction in the duration of hospital stay of group 2 patients (p<0.0001), with 62.8% of these patients staying less than 8 postoperative days. There was a reduction in the number of patients with thromboembolic complications (p<0.05) and no increase in overall complications or readmission rate. There was a trend to increased use of rehabilitation services among group 2 patients.
  
  
  CONCLUSIONS
  Clinical pathway implementation resulted in a significant reduction in the length of stay, and achieved a more efficient management of hospitalised patients without compromising outcome.
