The vastus medialis is one of the four muscles that make up the quadriceps femoris. The quadriceps femoris is a superficial muscle that defines the anterior thigh. When you work out and you don't skip a leg day, this will be the muscle that will be clearly defined right in the front of your thigh.
The vastus medialis is innervated by the femoral nerve. The vastus medialis as the name suggests is the part of the quadriceps femoris that is found medially - so towards the midline of your body. It runs spirally around the femoral shaft originating at the linea aspera and the intertrochanteric line of the femur and then merges with the quadriceps tendon for the most part. The quadriceps tendon then inserts at the tibial tuberosity via the patellar ligament.
Now knowing what places the vastus medialis will be attaching to allows you to understand what joints this muscle will be moving when it contracts. And, yes, the knee is the joint that is affected. The knee is the meeting point for the distal end of the femur, the proximal end of the tibia and the patella. The bone that you can feel in front of your knee.
In the full version of this video, we will cover the origins, insertions and innervation of the vastus medialis muscle, while focusing on the functions that the vastus medialis is involved in at the knee joint.

Great stuff

One thing to note is that as we get older we use this muscle more often and it often gets tight so it needs to be loosened. In most cases a lot of people experience knee pain due to tightness of this muscle pulling on the joints which causes irritation

Just confused with TIGHT terminology . I go to dry needling and she tells me tight tight and tight which is true too and many thanks to her. But the question is if I go to gym and muscle gets harder and then it’s tight or hard so how do u distinguish these if it’s problem? Yes I feel pain when I have problem but question is how is it possible by going to gym not getting muscle tight

What would cause numbness in the inner left side of the knee and it's immediate surrounding leg muscle (vastus medialus muscle nearest the knee)? To exercise my hamstrings, I was doing some heavy Leg Curls (machine) in the gym and about a day after, in addition to the normal DOMS, I notice numbness in the inner part of my right knee, again, the side where the vastus medialus is. There is also some pain in the upper outer quad as well (quad femoris). The knee is also a little weak in supporting my body weight and the muscle also seems "rubber band'ish" as well as numb. Any comments or suggestions?

I lost some of this muscle due to menopause, little by little. Is this normal? I'm 52

[@loveit4092]

No , because your T levels are supposed to go up not down

[@starlarkyt]
