The KT-2000 knee ligament arthrometer is frequently used by clinicians in determining the integrity of the anterior cruciate ligament. Researchers have questioned the reliability in using this device in reporting reliable results. The purpose of this study was to determine the influence of examiner experience in using the K^T-2000 knee ligament arthrometer. Thirteen subjects (age=22-45) were recruited on a voluntary basis for this study. The KT-2000 knee ligament arthrometer was used to measure anterior-posrtior laxity for each patient. Results were measured at 15 and 20 pounds of force for right and left knees. A multiple linear regression ANOVA was used to analyze the data. There was a significant difference found when comparing expert and novice testers (t=3.15; p=0.02). However, when comparing novice and experts to themselves, there was no significant difference found (t=0.19; p=0.05). The differences between the right and left knees were found not to be significant (t=0.23; p=0.05). Finally, the differences between measurements taken at 15 and 20 pounds of force were found to be significant (t=4.03; p=0.02). These results concluded that examiner experience did have an influence in using the KT-2000 knee ligament arthrometer.
