Description[edit | edit source]
The Vastus Medialis Oblique (VMO) muscle is the muscle that makes up the distal most fibres of the Vastus Medialis (VM) muscle of the Quadriceps.[1] The VMO and VM muscles are functionally different due to different orientation of muscle fibres. VMO runs obliquely and helps with medial translation of the patella where VM runs more longitudinally and contributes more to knee extension. Patellofemoral joint load is decreased by advanced and adequate medially directed force by the VMO.[2]
Origin[edit | edit source]
The VMO has multiple points of origin. The muscle fibres largely originate from the pubic points of the Adductor Magnus tendon. The other points of origin include the medial lip of linea aspera and the medial supracondylar line.[1][3]
Insertion[edit | edit source]
VMO inserts onto the medial border of the patella and the knee joint capsule. It also has a small area where it directly continues with the patella tendon[1].
Action[edit | edit source]
VMO assists with medial translation of the patella[2][1] and assists with the last phase of knee extension[1].
