The vastus medialis vastus medialis oblique, or VMO is one of the four quadriceps muscles in the front of your upper thigh.
The teardrop-shaped muscle helps move the knee joint and stabilizes the kneecap. Injury to the vastus medialis can cause knee pain and difficulty walking, running, or managing stairs. The vastus medialis originates from the intertrochanteric line on the inner part of your thigh bone femur. From there, it courses down the front and inner portion of the kneecap patella and joins the other quadriceps muscles rectus femoris, vastus intermedius, and vastus lateralis.
These muscles attach to the patella via the quadriceps tendon. The vastus envelopes the patella and inserts the patellar tendon on the front of your shin bone tibia. The vastus medialis is innervated by the femoral nerve , which comes out from your lumbar spine at level two, three, and four.
The femoral artery supplies blood to the vastus medialis. The vastus medialis is closer to the surface of your skin superficial than deeper muscles, so it's easy for you to find and feel palpate.
The vastus medialis works with the other quadriceps muscles to help you extend your knee joint. The muscle and its tendon go over the inner aspect of your knee, where it helps stabilize the kneecap. Your patella is situated in a small groove on the end of your thigh bone. The groove allows your kneecap to track up and down when you bend and straighten your knee.
As it tracks in the groove, the patella gets medial stability from the vastus medialis. The function of your vastus medialis can be impaired by several conditions, which can result from surgery, trauma, or athletic injuries.
Injury to the muscle can cause weakness, change how your knee moves, or affect your ability to walk and run. If you have knee pain or weakness, see your healthcare provider. They may refer you to a physical therapist who can help you recover. An injury to your knee or vastus medialis muscle may limit your normal functional ability. Rehabilitation will depend on the type of injury and your individual needs. For an acute injury to your vastus medialis, it's generally recommended that you allow some time for rest initially, then begin gentle movement as you heal.
Exercises that improve muscle flexibility and strength can help you fully regain mobility as well as prevent future problems.
Most quadricep injuries take at least six to eight weeks to recover. If you tear or strain your vastus medialis, the first treatment is a period of rest. You may need a knee brace or compression sleeve to support your knee and control swelling as you recover. After a week or so of rest, try starting gentle exercises such as heel slides, quad sets, and straight leg raises. Stretching for your quadricep will also gently elongate the muscle.
If your femoral nerve becomes pinched by arthritis or a bulging disc in your back, it can cause vastus medialis weakness and limit your ability to walk. The first step in treatment is to get the pressure off your femoral nerve to restore normal nerve communication with the vastus medialis. Once the nerve is free, you can use strengthening exercises to regain normal knee function. Since the vastus medialis is a major knee stabilizer, weakness in the muscle can be a cause of PFSS.
Treatment of PFSS involves improving vastus strength with quad sets, straight leg raises, and patellar tracking exercises. The position of your knee is controlled by your hip muscles gluteus medius. Treating PFSS can also involve strengthening your hip muscles along with your vastus medialis. Swelling is common after a knee injury or surgery and can inhibit the function of your quad and vastus medialis.
Heat or ice may be used to reduce swelling. Exercises like heels slides and stationary bike riding may also be useful. As part of your longterm recovery, you may work with a physical therapist to improve vastus medialis function. Physical therapists sometimes use a special type of neuromuscular electrical stimulation NMES to encourage the vastus contract properly and help regain normal muscle function.
The vastus medialis is one of the major muscles that help you move your knee. Being able to move your knee normal is necessary for walking, jumping, and climbing stairs.
If you injure the muscle, your normal functional ability may be affected. Depending on the reason the muscle is impaired, there are different options for treatment. Most involve a period of rest, then slowly starting with gentle exercise until your body is healed. Remember that your rate of healing won't be the same as someone else's. If you have an injury or condition that affects your vastus medialis, the amount of time it takes you to rehabilitate will depend on many factors.
It's important to work closely with your healthcare provider and physical therapist to ensure that your goals and expectations for recovery are realistic and that you stay motivated.
