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. With regards to how long it will take to see result; this depends. It may feel like following an exercise session that the muscle is bigger, but this will most likely be due to increased blood flow into the muscle.

Influence of age will play a role on muscle development. Fortunately, Progressive resistance training is a way of slowing down this process.

If this is something that is concerning you, I would seek further clarification in a clinical setting with GP, Neurologist or Physiotherapist. The key importance to remember is that strength increase can be achieved within a few weeks, but muscle growth will take a longer period of time. I highly recommend seeking a physiotherapist or exercise physiologist to develop your initial exercise program, so that you are performing adequate and appropriate strength exercises tailored to your needs. Regards, Patrick.

Thank you Patrick for your comments. I train for Spartan races by running both on both flat and mountain terrain between 5 and 15 miles. I build up week by week to attain the longer distances. On occasion I get a pain in my VMO. It may occur on one side at a time or in both. The pain does not feel like a cramp as I have experienced in my calves or feet pain and locking up.

It seems to happen if I extend my self to far when I add miles on my run compared to previous distances. My question is it simply muscle fatigue? Why do my other muscles not experience this issue? I have not had any knee issues so I do not believe that is an underlying issue? If it is not fatigue is there something else it could be? I will start performing your exercises listed above. Thanks again. Hi Todd, Thank you for your comment.

Anterior knee pain is unfortunately a common symptom experienced in casual and experienced runners. From your detailed explanation, there are 3 things that may be influencing your knee pain. Strengthening exercises will assist with improving running efficiency and muscular performance.

A minimum of weeks of resistance based exercise is required to achieve this performance goal. You can perform these exercises as an adjunct, concurrently with your running training.

The change of gradient has a significant impact on muscular usage. An article in shows that both incline and decline gradients have a significant increase in Quadriceps muscular activity. Similar to the reason above, I believe a strengthening program of the lower limb will assist with this. Finally, an alternative cause of your symptoms may be the patellofemoral joint Kneecap and Femur. It may also be known as Runner's knee, Chondromalacia patellae,….

Knee strengthening exercises should form part of a full rehabilitation program. Here we demonstrate some early, mid and late stage knee rehabilitation exercises for recovering…. This should be applied to both acute sudden…. Here we outline the common causes of knee pain. Acute knee injuries occur suddenly, usually from direct impact or twisting. Chronic knee pain develops gradually….

The majority of knee injuries, especially the minor ones can be treated at home. However, there are situations where you should seek professional medical advice. Skip to content VMO is short for vastus medialis oblique muscle. Click headings below to expand: Introduction to VMO strengthening exercises. Is my VMO muscle contracting properly? You should feel a strong contraction of the muscle under your fingers. If the muscle does contract, continue with strengthening exercises.

Patellofemoral taping If your patella is not tracking properly, or if you have pain when trying to perform VMO exercises then taping your patella can help. More on Patellofemoral pain taping. VMO strengthening exercises The following exercises strengthen the vastus medialis oblique muscle: Knee extension.
