title: Pain perception and its relation to functional status post total knee arthroplasty: a pilot study.
abstract: OBJECTIVE
  This pilot study examined the influence of pain perception on functional status.
  
  
  METHODS
  A descriptive longitudinal correlational exploratory design was used.
  
  
  METHODS
  The sample comprised 23 participants ranging in age from 47 to 85 years.
  
  
  RESULTS
  Data were collected for pain perception components, anxiety, and functional status. Negative correlations were noted between pain and functional status on days 42 and 84. Common descriptors used over the first 3 days were sharp, aching, tender, and tiring.
  
  
  CONCLUSIONS
  Pain intensity is only one component of pain perception. Management of the sensory and affective components needs further research.
