What are the 4 main stabilizing structures of the knee?
Knee Joint Stabilisation
- quadriceps femoris and extensor retinaculum.
- pes anserinus.
- popliteus.
- biceps femoris.
- semi-membranosis.
What would happen to non contractile structures under prolonged loading?
In case you’re not familiar, creep is the deformation of a structure that happens following prolonged loading. In this instance the non-contractile, viscoelastic tissue increases in length.
What structures of the knee are intracapsular?
The knee joint is also strengthened by the intracapsular structures, which include the cruciate ligaments and menisci. The two cruciate ligaments are located within the fibrous joint capsule so are intracapsular, but lie outside of the synovial lined articular cavity as we said before so are considered extra-articular.
What structures are unique to the knee joint?
The range of motion of the knee is limited by the anatomy of the bones and ligaments, but allows around 120 degrees of flexion. A special characteristic of the knee that differentiates it from other hinge joints is that it allows a small degree of medial and lateral rotation when it is moderately flexed.
What are the secondary Stabilisers of the knee?
The secondary stabilisers of the knee joint are all the muscles surrounding the knee alongside the hip muscles and the gastrocnemius muscle.
What are the 4 ligaments of the knee?
The knee has 4 major ligaments. Ligaments connect bones to each other. They give the joint stability and strength….They are:
- Anterior cruciate ligament (ACL).
- Posterior cruciate ligament (PCL).
- Medial collateral ligament (MCL).
- Lateral collateral ligament (LCL).
Which of the following injuries is a consequence of microtrauma or repetitive stress?
Repetitive microtrauma can cause soft tissue and bone injuries. Muscle injuries include contusions, strains, tendinopathy, and complete rupture.
What is load biomechanics?
The term “load” describes physical stresses acting on the body or on anatomical structures within the body. These stresses include kinetic (motion), kinematic (force), oscillatory (vibration), and thermal (temperature) energy sources.
What ligaments of knee are intracapsular?
Intracapsular ligaments are found inside the joint capsule, with the cruciate ligaments being the most well known of this subgroup.
- Patellar ligament. Patellar ligament.
- Lateral (fibular) collateral ligament. Fibular collateral ligament of knee joint.
- Oblique popliteal ligament.
- Cruciate ligaments.
- Menisci.
Which ligaments are extracapsular and intracapsular?
They differ by their location within a joint. Ligaments that are presented as the local thickening of the articular capsule are called the capsular ligaments, while the ligaments located outside or inside the capsule are called extracapsular and intracapsular ligaments respectively.
What are the primary and secondary Stabilisers of the knee?
The knee ligaments are the primary stabilisers, and the muscles are the secondary stabilisers of the knee.
Is the MCL intracapsular?
The knee has two extracapsular ligaments. The medial collateral ligament (MCL) is located on the inside, or medial, surface of the knee. The lateral collateral ligament (LCL) runs along the outside, or lateral, knee surface.
