      Arteries: A Focus on the Middle Genicular Artery.

AB  - The aim of the study was to gain an appreciation of the variation in the 
      branching pattern and diameter of the genicular arteries arising directly from 
      the popliteal artery (PA), namely, the superior medial genicular artery (SMGA), 
      superior lateral genicular artery (SLGA), inferior medial genicular artery 
      (IMGA), inferior lateral genicular artery (ILGA), and middle genicular artery 
      (MGA). Twenty cadaveric knees aged between 62 and 92 years were dissected. A 
      posterior midline vertical incision was used to gain access to the PA. The 
      diameter of the PA, the sequence of branching, and subsequent diameter of 
      genicular vessels and common trunks were recorded. PA average diameter was 7.9 
      mm. The SMGA (1.6-mm diameter) was the first branch in 45% and the second branch 
      in 20%, and in seven limbs it arose from a common trunk with the SLGA. The SLGA 
      was the second branch in 30% and the first branch in 25%, and it branched from a 
      common trunk in 45%. The MGA (1.1-mm diameter) arose as the second branch in four 
      knees and as the third branch in eight knees. It arose from a common trunk in 
      eight knees, either with a superior genicular (three knees) or with an inferior 
      genicular (five knees). The IMGA (1.5-mm diameter) was the third branch in 25%, 
      the fourth branch in 35%, and the fifth branch in 15%. In five cases, it arose 
      from a common trunk (25%). The ILGA (1.4-mm diameter) was the third branch in 
      15%, the fourth branch in 30%, and the fifth branch in 25%. It arose from a 
      common trunk in six knees. These trunks also gave rise to the IMGA in all cases. 
      There is extensive variation in the branching pattern and diameter of the 
      genicular arteries differing from textbook descriptions. An awareness of vascular 
      variation is imperative for preservation of the blood supply to the knee, which 
      may promote recovery after anterior cruciate ligament reconstruction and 
      popliteal aneurysm repair.
