title: Satisfaction With Knee Function After Primary Anterior Cruciate Ligament Reconstruction Is Associated With Self-Efficacy, Quality of Life, and Returning to the Preinjury Physical Activity.
abstract: To assess whether patient-reported outcomes (psychological factors, appraisals of knee function, and physical activity participation) were associated with satisfaction with knee function after anterior cruciate ligament (ACL) reconstruction.
  
  
  
  Participants who were aged 18 to 45 years and a minimum 12 months post primary ACL reconstruction completed a questionnaire battery evaluating knee self-efficacy, knee-related quality of life, self-reported function, and physical activity participation. Participants' responses to the question "If you were to spend the rest of your life with your knee just the way it has been in the last week, would you feel . . . (7-point ordinal scale; 1 = happy, 7 = unhappy)" were categorized as satisfied, mostly satisfied, or dissatisfied and used as the primary outcome. Ordinal regression was used to examine associations between independent variables and the primary outcome.
  
  
  
  A total of 177 participants were included at an average of 3 years after primary ACL reconstruction. At follow-up, 44% reported they would be satisfied, 28% mostly satisfied, and 28% dissatisfied with the outcome of ACL reconstruction. There were significant differences in psychological responses and appraisal of knee function between the 3 groups (P = .001), and significantly more people in the satisfied group had returned to their preinjury activity (58%) than in the mostly satisfied (28%) and dissatisfied (26%) groups (P = .001). Multivariable analysis demonstrated that the odds of being satisfied increased by a factor of 3 with higher self-efficacy, greater knee-related quality of life, and returning to the preinjury activity.
  
  
  
  People who had returned to their preinjury physical activity and who reported higher knee-related self-efficacy and quality of life were more likely to be satisfied with the outcome of ACL reconstruction.
