GNRB KNEE ARTHROMETER: MORE THAN JUST OBJECTIVE RESULTS ON THE ACL...
In August 2017, Genourob celebrated its 10th year anniversary marking a decade of research & development in the field of knee ligament diagnosis & treatment. This past period was indeed marked with great advancements in this particular branch of study and there is no doubt saying that Genourob clearly contributed to this evolution.
The GNRB, a story that began 10 years ago...
When talking about the knee arthrometers that are present on the orthopaedic market today, it is often only mentioned that these allow the objectification of tests run on the ACL. While this attribute may be the main characteristic of these tools, we at Genourob, quickly understood that we had to come up with additional features to make our medical device stand out as an innovation.
Therefore, by means of extensive studies conducted by recognized orthopaedic surgeons around the world over the past 10 years, our experienced R&D team remained attentive with an open mind to the critics made towards our device: as a result, the GNRB is now recognized as the most precise and reliable arthrometer present on the market (see scientific studies).
Opt for Reproducibility in addition to Accuracy
In the beginning of the GNRB's development, the reproducibility characteristic was quickly mentioned as we always intended to create the first automated arthrometer. Our initial thinking was indeed to design a tool replicating the Lachman test to help doctors in the diagnosis and treatment of ACL injuries.
Further to this, in order to be as accurate as possible, we got the most precise sensors installed but quickly realized that initial testing conditions had a direct impact on the results obtained. What was the point of getting precise sensors if we could not even put our patient in the same position each time we tested him/her? Result comparison is indeed crucial in this field (ACL treatments last between 6 months to 2 years) so we were convinced a solution had to be found regarding this issue.
After some reflexion, we came up with this idea of adding several additional sensors and parameters . A tightening sensor and a ruler were therefore installed in order to guide the healthcare professional in the positioning.
As a result, the GNRB quickly rose to fame among the orthopaedic community as a reliable tool for testing the ACL. This additionally led this community in realizing that following the state of the ACL graft over the months following the surgery has a great benefit on knee stability during the years following surgery (see study of B. Semay - 2016). Choosing the correct rehab exercises following the results obtained indeed significantly maximize the chances of gaining knee stability.
