Topography of the Middle Genicular Artery is Associated with the Superior and Inferior Genicular Arteries

Abstract: SUMMARY:Total knee arthroplasty has increased substantially, however anatomical studies of the genicular arteries (GAs) in this region are rare. The aim of this study was to identify the pattern and branching points of GAs and their relationship. In 42 lower limbs, the pattern and branching points of GAs were confirmed. The horizontal line which extends between the most prominent point of the lateral and medial margins of patella was defined as a reference line. The distance of branching point of the GAs from … Show more

“…Comparing the studies, we decided to use the posterior tibial plateau as our reference line (joint line) as this is an easily identifiable landmark during surgical procedures. Although we do not know precisely where the anatomic joint line falls in relation to the reference line in theYang et al (2017) study, they showed the ILGA branching from the PA 18.46 mm inferior to the designated reference line and the IMGA branching 24.09 mm inferior to the reference line.…”

“…The branching location of the five genicular arteries from the PA in the posterior knee as well as the variations in genicular artery branching patterns have previously been studied (Bettaiah, Sangeetha, & Saraswathi, 2016;Yang et al, 2017); however, no F I G U R E 1 Posterior view of the knee at the popliteal fossa. Line A: distance between the genicular artery branch point from the popliteal artery (PA) and joint line (JL) was measured.…”

“…Cadaveric studies have previously reported variations in genicular arterial anatomy and proposed two different classification patterns. 18,19 The classification types mainly involve differences in the middle genicular artery (MGA) branching pattern and its common origin with other genicular arteries. The MGA was not treated in the present study given its limited perfusion of the knee.…”

“…29 Yang et al subsequently demonstrated that variations in the origin of the middle geniculate artery were associated with substantial variations in the origin of the other arteries of the geniculate system. 30 Salaria et al found the middle geniculate artery formed a near right angle relative to the popliteal artery in flexion, which may place it at risk during tibial preparation in TKA. 32 Any aberrant retractor placement or inadvertent contact with an invasive instrument (i.e., oscillating saw or osteotome), places these delicate vascular structures at risk.…”
