WHERE CAN I ORDER A KT1000 KNEE LIGAMENT ARTHROMETER?
The KT1000 is a medical tool that was developed by the company MEDMETRIC. The purpose of this instrument is to objectively assess knee laxity by measuring the displacement of the tibia relative to the femur alike the GNRB arthrometer. Results provided from the KT1000 enable medical practitioners to diagnose the state of the anterior cruciate ligament (ACL).
Where can I order a new KT1000 or a KT2000?
Nowadays, it is not possible to order a new KT1000 or KT2000 arthrometer as the company MEDMETRIC recently terminated production of these instruments. The device having been developed since the 1980's, the company decided to cess manufacturing it in 2015.
Fortunately, there are alternative solutions:
- 1) Order a second hand KT1000 arthrometer
- 2) Buy a newer & more advanced arthrometer: Genourob's GNRB & DYNEELAX knee laxity testing devices
By choosing 1), the price of a second hand KT1000 arthrometer is around 7,000$. This solution might be appealing at first but does not come without a risk, as the device that will be acquired might be faulty since it was manufactured some time ago. Consequently, there is no warranty when buying such a device and it might be delivering its final tests. In addition, it can be difficult finding someone selling it.
By opting for 2) however, you will obtain a newer tool offering more advanced features such as higher accuracy & reproducibility which are described below or you can click here. Also, it comes with a warranty that lasts 2 years.

Dyneelax Knee Laxity Arthrometer
The GNRB or Dyneelax are medical tools that were developed since 2007 by the company GENOUROB. At first, the devices were designed to only apply anterior tibial translation for diagnosing the ACL. However, these tools can also provide assessments on the PCL or medial rotation instability using additional options.
What makes the GNRB & Dyneelax the leading arthrometers on the market is mainly that fact that these are completely automated. This attribute indeed facilitates the user in performing objective tests that are highly accurate & reproducible as all forces are manually chosen via a computer. For example, the tibial displacements can be calculated from 0 to 150N or from 0 to 200N.

GNRB Test results
Results are then given under the form of compliance curves (=opposite of stiffness curves), which help the medical practitioner in diagnosing and treating injuries related to the knee ligaments. Further to this, automation also permits the analysis of the slope of the compliance curves (=opposite of stiffness curves) that is an innovative diagnosis technique regarding knee stability (see GNRB scientific study) in addition to the side-to-side displacement differential diagnostic technique.
