Presently, the GNRB device provides the best precision in regards of knee ACL laxity assessement as it is the only arthrometer (aka. laximeter) able to objectively evaluate knee stability because of the dynamic tests it runs. While designing this tool, user friendliness was for us one of the major aspects that had to be taken into account. This consequently lead to many parameters and sensors being considered in order to guide the users while running dynamic tests. Thanks to these parameters and sensors, precise test reproducibility is now one of the top attributes the GNRB has to offer among many other. Further-more, the LDA® Method, which is an integral part of the GNRB, is perhaps what makes this device leader in the field of ACL analysis. The results given after a test are shown under the form of compliance curves (=opposite of the stiffness curves) accompanied by a table chart that generate sensible data to practitionner.
