What is Knee Laxity?
In the knee, ligaments are present to connect and stabilise the various bones that are present. These ligaments are very useful as these make sure the knee joint is flexible enough to move but also firm enough to provide support.
Running or sitting would hence not be possible without these ligaments.
Typically, the average human being has naturally tight ligaments. However, in some cases, these knee ligaments can be loose and this can be referred to as “high knee laxity”.
Loose knee joints or knee joint laxity is also often associated with knee ligamentous laxity.
What are the Symptoms & Causes of Knee Ligamentous Laxity?
Knee ligamentous laxity occurs in or around the joint. The symptoms include :
- Pain, numbness, or tingling
- Frequent injuries or knee joint dislocation
- Muscle spasms
- Knee joints that click or crack
- Increased knee range of motion (hypermobility)
It is not uncommon to have loose knee joints. Children often have high knee ligamentous laxity.
Usually, it is due to an injury or a certain medical condition. Furthermore, adults with loose ligaments have a higher risk of injury.
How is Knee Ligamentous Laxity Diagnosed?
Knee ligamentous laxity can be diagnosed using a knee arthrometer such as the Genourob DYNEELAX, the GNRB or the KT-1000 or doing some physical tests like the Lachman test or the anterior drawer test.
Knee arthrometers are medical devices designed to apply various movements on the tibia to measure the joints’ motion. The movements are then analysed to determine the state of resistance of the various ligaments present in the knee.
Using an arthrometer is advised as the results are objective and reproducible. Consequently, the doctor may directly know whether the ligaments are loose or not and prescribe the proper treatment.
Genourob’s 4-in-1 Arthrometer
Genourob has pushed the boundaries of arthrometry by designing and marketing the Dyneelax knee laxity arthrometer, an arthrometer that is capable of applying both rotation and translation on the tibia to assess the various ligaments and ligamentous structures present in the knee.
Dyneelax is a 4-in-1 device as it allows diagnosis, prevention, rehabilitation and follow-up of patients suffering from knee ligament injuries.
It is currently the most accurate & reproducible knee arthrometer regarding knee ligament assessment as it is the only one that is completely automated and computerised.
As the tests are fully motorised, these tests can be done before and after surgery.
