What is KT-1000?
What is KT-1000?
The KT-1000 knee arthrometer (KT-1000) is an objective instrument to measure anterior tibial motion relative to the femur for anterior cruciate ligament (ACL) reconstruction. Four studies between 1950 and 2007 regarding validity of the KT-1000 were identified using a Medline search.
What is KT test?
The KT-1000 test is performed to provide an objective assessment of the amount of increased anterior knee translation between 20 and 30 degrees of knee flexion.
What is a Arthrometer used for?
An UpToDate review on “Anterior cruciate ligament injury” (Friedberg, 2013) states that “The KT-1000 knee ligament arthrometer is a device that provides an objective measurement of anterior-posterior translation and is often used in studies evaluating ACL tears.
What is a joint Arthrometer?
An arthrometer measures joint motion. In this position the patella is engaged in the trochlea, so that it does not move during assessment of tibial movement relative to the femur. The arthrometer unit is placed on the anterior tibia and held in place with Velcro straps around the calf.
What is kt2000?
KT-1000 arthrometer : Knee laxity Testing Device KT-1000. The KT1000 arthrometer was designed to measure the anterior translation of the tibia while maintaing the femur in position. The results obtained provide an objective diagnostic of the state of the ACL to the medical practitioner.
What does a positive Lachman test look like?
Anterior translation of the tibia associated with a soft or a mushy end-feel indicates a positive test. More than about 2mm of anterior translation compared to the uninvolved knee suggests a torn ACL (“soft end-feel”), as does 10mm of total anterior translation.
What is the KT-1000 knee arthrometer used for?
The KT-1000 knee arthrometer (KT-1000) is an objective instrument to measure anterior tibial motion relative to the femur for anterior cruciate ligament (ACL) reconstruction. Four studies between 1950 and 2007 regarding validity of the KT-1000 were identified using a Medline search. One had interpre …
What kind of motion does the kt1000 measure?
The KT1000™ was developed to provide objective measurement of the sagittal plane motions of the tibia relative to the femur. This motion, sometimes referred to as drawer motion, occurs when an examiner applies force to the lower limb or when the muscles of the quadriceps are contracted.
Which is more accurate GNRB or kt1000 arthrometer?
Nowadays, it is considered that a KT1000 test is clinically more accurate and useful when diagnosing ACL instability compared to an MRI scan. This arthrometer can also be used to follow-up post-operative results, but the fact that the forces are applied manually represents a risk (risk not present with the GNRB arthrometer).
