title: Quality of life after knee revision arthroplasty.
abstract: OBJECTIVE
  Radiographic and clinical survival analyses of revision total knee replacement (TKR) are considered acceptable outcome measures. However, the full influence of revision knee replacement on the overall health status of patients remains poorly defined.
  
  
  METHODS
  We prospectively studied the health-related quality of life outcome in 94 patients who underwent revision knee replacement surgery over a 5-year period. Comparisons were drawn between the Nottingham health profile (NHP) scores and the Knee Society score pre-revision, and those obtained at 3 months, 1 year and 5 years after revision knee arthroplasty.
  
  
  RESULTS
  We found a significant improvement in Knee Society score and NHP pain scores 3 and 12 months after revision TKR (p < 0.05). No other modalities of the NHP showed a significant change. 5 years after surgery, pain was less than before revision (p = 0.2), but energy level was considered worse (p = 0.07). Knee Society scores were found to be higher pre- and postoperatively for patients undergoing revision for reasons other than sepsis than for patients with sepsis. Patients requiring implantation of a hinged prosthesis also had lower Knee Society scores than those patients receiving a non-hinged implant. Repeated revision was associated with a downward trend in Knee Society score with each surgical intervention.
