Patellar network
(Redirected from Patellar anastomosis)
Patellar Network[edit | edit source]
The patellar network is a complex arrangement of nerves and blood vessels that supply the knee joint, particularly the patella or kneecap. This network is crucial for the proper functioning of the knee, providing both sensory and motor innervation as well as vascular supply to the surrounding tissues.
Anatomy[edit | edit source]
The patellar network is composed of several key structures:
- Femoral nerve: This is the primary nerve supplying the anterior compartment of the thigh, and it gives off branches that contribute to the innervation of the patellar region.
- Saphenous nerve: A branch of the femoral nerve, the saphenous nerve provides sensory innervation to the medial aspect of the knee and the patellar region.
- Genicular arteries: These are branches of the popliteal artery that supply blood to the knee joint, including the patella. They form an anastomosis around the knee, known as the genicular anastomosis.
Function[edit | edit source]
The patellar network serves several important functions:
- Sensory innervation: It provides sensation to the skin overlying the patella and the anterior knee joint, allowing for the perception of pain, temperature, and touch.
- Motor innervation: Although the patellar network primarily provides sensory innervation, it also plays a role in the reflexive actions of the knee, such as the patellar reflex.
- Vascular supply: The network ensures adequate blood flow to the patella and surrounding structures, which is essential for maintaining tissue health and facilitating healing processes.
Clinical Significance[edit | edit source]
Injuries or conditions affecting the patellar network can lead to various clinical issues:
- Patellar tendinitis: Inflammation of the tendon connecting the patella to the tibia, often due to overuse.
- Patellofemoral pain syndrome: Pain around the patella, often related to imbalances in the forces acting on the knee joint.
- Knee bursitis: Inflammation of the bursae around the knee, which can affect the patellar network.
