Where does the vastus medialis originate?
The vastus lateralis and vastus medialis mostly take origin from the linea aspera of the femur. The vastus intermedius arises from the anterior surface of the femur deep to the rectus femoris. Unlike the other members of the quadriceps, the vastus medialis is fleshy at its lower end and these fibres lie horizontally as they attach to the patella. It can be seen on the surface in a muscular person ( Fig. 6.8 ).

What muscle is used to flex the hip and knee?from sciencedirect.com
Sartorius assists flexion of both the hip and the knee and is a lateral rotator of the thigh at the hip and a medial rotator of the knee when the knee is in a flexed position. Levangie & Norkin (2005) note that its function is most important when the hip and knee need to be simultaneously flexed, as in stair climbing. Travell & Simons (1992) note that it ‘earned its name as the muscle that assists the hip movements necessary to assume the position of a cross-legged tailor (sartor, a tailor)’. Its trigger point pattern primarily runs along the course of the muscle.
Which fibers attach to the lateral femoral condyle?from sciencedirect.com
They note that posterolateral fibers join the iliotibial band, which attaches to the lateral condyle of the tibia; however, some deep fibers attach to the lateral femoral condyle and linea aspera of the femur. At the proximal end, they note that variations include a slip to the inguinal ligament, fusion with gluteus maximus to ‘ form a muscular mass comparable to the deltoid muscle of the shoulder ’ and that the entire muscle is sometimes congenitally absent as a family trait.
Which direction does the patella move?from sciencedirect.com
The long axis of the shaft of femur is not vertical but slants downwards and medially. Therefore when the quadriceps contracts its direction of pull is upwards and lateral, causing the patella to move in the same direction. The patella thus has a tendency for dislocating upwards and laterally. Pull of the lower horizontal fibres of the vastus medialis is an important factor preventing such dislocation.

Attachments: Anterior aspect of the outer lip of iliac crest, lateral surface of ASIS and deep surface of the fascia lata, descending between the gluteus medius and sartorius to merge into the iliotibial band (tract) usually about one-third of the way down the thigh, ‘although it may reach as far as the lateral femoral condyle’ ( Gray's anatomy 2005 ). The iliotibial band attaches to the lateral tibial condyle. (See below for additional attachment details from Travell & Simons 1992 .)
