The acetabulum is also home to the acetabular fossa, an attachment site for the ligamentum teres, a triangular, somewhat flattened band implanted by its apex into the antero-superior part of the fovea capitis femoris. The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves ...
The acetabular branch is an artery in the hip that arises from the medial circumflex femoral artery opposite the acetabular notch and enters the hip-joint beneath the transverse ligament in company with an articular branch from the obturator artery.
The medial femoral circumflex artery (with its branches) supplies arterial blood to several muscles, including: the adductor muscles of the hip, gracilis muscle, [1] [3] pectineus muscle, [3] and external obturator muscle. [1] It delivers most of the arterial supply to the femoral head and femoral neck via branches - the posterior retinacular ...

The acetabular notch is a deep [citation needed] notch in the inferior portion of the rim of the acetabulum. [ 1 ] : 1354 It is bridged by the transverse acetabular ligament , converting it into a foramen (through which nerves and vessels (including the acetabular notch of obturator artery [ 1 ] : 1250 ) pass into the hip joint cavity).
The lunate surface of acetabulum is the articular surface of the acetabulum which makes contact with the femoral head as part of the hip joint. It forms an incomplete ring that is deficient inferiorly - opposite the acetabular notch .
The transverse acetabular ligament (transverse ligament [1] or Tunstall's ligament [citation needed]) bridges the acetabular notch, creating the a foramen (through which blood vessels and nerves pass into the joint cavity). [2] The ligament is one of the sites of attachment of the ligament of head of femur. [1] [3]: 789
Five genicular arteries branch from the popliteal artery to form a network around the knee, the genicular anastomosis. The anastomosis provides collateral circulation in the event of damage to the region. [1] Inferior or distal to the origin of the descending genicular artery are two superior genicular arteries: Medial superior genicular artery
