Comparison of the single assessment numeric evaluation method and the Lysholm score

The purpose of this study was to determine the correlation between the Lysh olm knee score and the Single Assessment Numeric Evaluation method. Between March 1995 and December 1996, 201 followup examinations were performed on 130 college age patients who had undergone anterior cruciate ligament recon structions. These 201 examinations were divided into five routine follow-up categories: 3 months, 6 months, 1 year, 2 years, and greater than 2 years, The Lysholm score from each patient's followup questionnaire was correlate d with his or her Single Assessment Numeric Evaluation rating, as determine d by his or her written response to the following question: On a scale from zero to 100, how would you rate your knee today (100 being normal)? All da ta mere gathered prospectively, The mean Lysholm scores and Single Assessme nt Numeric Evaluation ratings ranged from 83.0 to 93.4 points and 80.0 to 9 3.3 points, respectively, The correlation coefficients between the Lysholm scores and the Single Assessment Numeric Evaluation ratings ranged from 0.5 8 to 0.87 points. The results of this study indicate that Single Assessment Numeric Evaluation ratings correlate well with measured Lysholm scores in patients with anterior cruciate ligament reconstruction, The Single Assessm ent Numeric Evaluation provides clinicians with an alternative mechanism to gather outcomes data with little demand on time and resources.
