Prospective comparative study of knee laxity with four different methods in anterior cruciate ligament tears

摘要

Anterior knee laxity can be evaluated using different devices, the most commonly used being the TelosA (R), KT1000A (R), RolimeterA (R), and GNRBA (R). However, the laxity values obtained with these devices have never been compared to one another. As such, the outcomes of studies using these different knee laxity measurement devices may not be comparable. The primary purpose of this study was to determine the side-to-side laxity difference in patients with one ACL-injured knee, using each of these devices, and to compare the values obtained from each. We hypothesized that the measurements of laxity would vary depending on the device used.
