Popliteal artery: Nerve: Tibial nerve: Actions: Medially rotates tibia on the femur if the femur is fixed (sitting down) or laterally rotates femur on the tibia if tibia is fixed (standing up), unlocks the knee to allow flexion (bending), helps to prevent the forward dislocation of the femur while crouching: Identifiers; Latin
The bones of the popliteal fossa are the femur and the tibia. Like other flexion surfaces of large joints ( groin , armpit , cubital fossa and essentially the anterior part of the neck ), it is an area where blood vessels and nerves pass relatively superficially, and with an increased number of lymph nodes .
Standard popliteal bypass surgery involves the bypass of the popliteal artery. [5] During surgery, incisions are made depending on the location of the blockage. [3] Usually, a healthy vein is located and sewn above and below the blockage to bypass the narrowed or blocked femoral artery. [6]
The intercondylar fossa of femur (intercondyloid fossa of femur, intercondylar notch of femur) is a deep notch between the rear surfaces of the medial and lateral epicondyle of the femur, two protrusions on the distal end of the femur (thigh bone) that joins the knee.
[1] [verification needed] [2] Its superior attachment is at the lateral epicondyle of the femur (superoposterior to the popliteal groove); its inferior attachment is at the lateral aspect of the head of fibula (anterior to the apex). The LCL is not fused with the joint capsule.
The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris.
The other two borders of the femur are only slightly marked: the lateral border extends from the antero-inferior angle of the greater trochanter to the anterior extremity of the lateral condyle; the medial border from the intertrochanteric line, at a point opposite the lesser trochanter, to the anterior extremity of the medial condyle.
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle.It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
