TI  - Two-Year Recall Bias After ACL Reconstruction Is Affected by Clinical Result.
LID - 10.2106/JBJS.OA.20.00164 [doi]
LID - e20.00164
AB  - Recall bias is a systematic error caused by inaccuracy in reporting past health 
      status and can be a substantial methodological flaw in the retrospective 
      collection of data. Little is known about recall bias following anterior cruciate 
      ligament reconstruction (ACLR). The purpose of this study was to evaluate 
      patients' recall bias regarding preinjury knee function at 2 years after ACLR. 
      METHODS: Patients undergoing ACLR were enrolled in an institutional ACL registry. 
      Preoperatively and at 2 years postoperatively, patients quantified their 
      preinjury knee function on a scale of 0 to 10 (10 = best). Recall bias was 
      quantified as the difference in the reported preinjury function between the 2 
      time points. The clinical result of ACLR was evaluated according to the 
      International Knee Documentation Committee (IKDC) Subjective Knee Evaluation 
      score. Patients meeting the minimal clinically important difference (MCID) in the 
      IKDC score were considered to have had a good outcome, while patients who did not 
      reach the MCID were considered to have had failure of treatment. Recall bias was 
      compared between the 2 groups. RESULTS: Of 2,109 patients enrolled in the 
      registry, 1,219 were included in the study. Patients with a good outcome 
      remembered their preinjury knee function on a 0-to-10 scale to be better than 
      what they reported at baseline, by a mean difference of 0.40 points (95% 
      confidence interval [CI], 0.22 to 0.58 points). The recall bias was stronger for 
      patients with a poor outcome, who remembered their knee function to be worse than 
      reported at baseline, by a mean difference of -0.81 (95% CI, -1.4 to -0.26). The 
      mean difference in recall between the 2 groups was -1.21 (95% CI, -1.74 to -0.67) 
      (p < 0.0001). CONCLUSIONS: The recall bias of preinjury knee function following 
      ACLR was small and not clinically meaningful for the majority of patients. 
      However, patients with a poor outcome had a clinically relevant and significant 
      recall bias. CLINICAL RELEVANCE: Our findings suggest that patients with a poor 
      outcome have a substantial recall bias. This has clinical relevance when 
      considering treatment effects of revision surgery, whereby the clinical benefit 
      of the treatment might be affected by recall bias.
