Definition

1. Noun:
   • A vein draining blood from the structures around the knee joint: The genicular vein is a blood vessel that collects deoxygenated blood from the tissues in the vicinity of the knee. It is part of the venous system that returns blood from the leg.
   • A vein that empties into the popliteal vein: Specifically, the genicular vein drains into the popliteal vein, which is the major vein located behind the knee.

Usage Examples

• Noun:
  • During the surgery, the surgeon carefully avoided damaging the genicular vein.
  • A thrombosis in a genicular vein can cause localized swelling and pain near the knee.

Advanced Usage

• Anatomical context: The term is primarily used in medical, anatomical, and surgical contexts. It is often discussed in relation to knee surgery, vascular studies, or descriptions of lower limb anatomy.
  • The angiogram clearly showed the patency of the genicular veins.
• Plural form - "genicular veins": There are typically several genicular veins (e.g., superior, middle, inferior) surrounding the knee.
  • The network of genicular veins provides collateral circulation around the knee joint.

Variants and Related Words

• Genicular arteries (n): The corresponding arteries that supply oxygenated blood to the knee region.
  • The genicular arteries anastomose (connect) with the genicular veins to form a network around the knee.
• Popliteal vein (n): The larger vein into which the genicular veins drain.
  • The popliteal vein receives blood from the genicular veins and the small saphenous vein.

Synonyms

• Articular vein of the knee: A descriptive synonym emphasizing its location around the knee joint.
• (Note: In precise anatomical terminology, "genicular vein" is the standard term; synonyms are descriptive rather than exact.)
