Articularis Genu Muscle
What is Articularis Genu Muscle?
The Articularis genu is a tiny muscle that is thought to be the fifth head of the Quadriceps muscle. It is deep in the vastus intermedius muscle and has been found to play an essential mechanical role in knee movement.
Origin of Articularis Genu Muscle
A deep femur from the distal to the vastus intermedius.
Insertion
The joint capsule and suprapatellar bursa.
Nerve
A medial deep part of the femoral nerve (L2-L4).
Artery
Lateral femoral circumflex artery.
Function of Articularis Genu Muscle
During extension, it drags the synovial membrane of the knee joint superiorly.
Control synovial membrane impingement between the femur and patella.
Keeps the patella and helps to stabilize the knee joint.
Help in the lubrication of the knee joint
Clinical relevance
The muscle assumes a critical part in both knee flexion and extension. At the point when the knee is broadened, it pulls the suprapatellar bursa vertically to control impingement between the femur and tibia. When this muscle doesn’t work right, it can cause suprapatellar bursitis, which hurts when you move your knee. The bursa inflammation or swelling is known as bursitis.
Assessment
Acute Bursitis might be because of injury, contamination, and crystalloid joint condition, and this patient presents with erythema, warmth, and tenderness with palpation and may influence ROM optional to inconvenience. On the other hand, chronic bursitis can be caused by diabetes or the long-term use of steroids. It can also be caused by heavy lifting for a hobby or job.
Chronic bursitis is usually not painful. Imaging may be helpful in addition to a patient’s history and physical exam. For example, an X-ray is important in acute cases caused by a fracture; a US can tell the difference between cellulitis and an inflamed bursa, and an MRI can help find another diagnosis.
Articularis genu muscle exercise
Lie down on the floor. Straighten both of your legs. Place a towel roll under the knee. By the knee, press the towel. Hold for 10 seconds and recount multiple times.

FAQ
What is the articularis genus’s purpose?
The articularis genu is a little level muscle of the anterior knee. It prevents impingement of the synovial folds between the femur and the patella by acting to tighten the synovial membrane superiorly when the knee is extended.
What is the other name for articularis genu?
subcrureus muscle The subcrureus muscle, which is also known as the articularis genus, is a small skeletal muscle on the thigh, just above the knee.
Where is the genus articularis?
A small muscle called the Articularis genu (Subcrureus) is usually distinct from the Vastus intermedius, but it can sometimes blend in with it; It is inserted into the upper portion of the synovial membrane of the knee joint from the anterior surface of the lower body of the femur.
What is the articularis genu attachment?
The articularis genu is a ribbon-shaped muscle that grows deep into the vastus intermedius muscle on the anterior surface of the distal quarter of the femoral shaft. It attaches distally to the superior border of the suprapatellar bursa and the synovial membrane of the knee joint.
