Understanding the Teardrop Muscle
The teardrop muscle is a vital component of the thigh, known anatomically as the vastus medialis. It plays a crucial role in the functionality of the knee and contributes to overall stability.
The vastus medialis, or teardrop muscle, is one of four muscles that make up the quadriceps group. It is located on the upper inside of the knee, extending down to the knee joint. This muscle is pivotal for extending the leg at the knee and stabilizing the patella, commonly referred to as the kneecap [1].

Weakness or injury in the vastus medialis can lead to issues with mobility, especially during weight-bearing activities such as running or climbing stairs [2].
Role in Knee Stability
The vastus medialis plays a significant role in knee stability. By ensuring the patella remains properly aligned during movements, it helps prevent knee injuries and promotes efficient movement patterns. The muscle contracts to help control patellar tracking, which is essential for maintaining knee health.
When the vastus medialis is weak or inactive, it can lead to improper tracking of the kneecap, potentially resulting in conditions such as patellofemoral pain syndrome. This underscores the importance of properly developing and maintaining strength in the teardrop muscle for overall knee health.

Importance of VMO Training
The vastus medialis obliquus (VMO), often referred to as the teardrop muscle, is integral to knee stability and overall lower body function. Proper training of this muscle can yield significant benefits in preventing injuries and ensuring proper patella tracking.
Preventing Knee Injuries
Specific training of the VMO is crucial for maintaining patella position and limiting knee injuries. Weakness or fatigue in this muscle can lead to incorrect tracking of the patella during movement, which puts extra stress on the knee joint. This misalignment can result in various injuries such as patellofemoral pain syndrome, anterior cruciate ligament (ACL) tears, and tendinitis [1].
By incorporating exercises that strengthen the VMO, individuals can enhance their knee stability, reduce the risk of injuries during physical activities, and improve overall athletic performance. A well-conditioned VMO can help absorb shock and minimize strain on surrounding ligaments and cartilage.
Injury TypeCausePatellofemoral Pain SyndromeWeakness or fatigue in VMO leading to mal-trackingACL RuptureInadequate support from muscles around the jointChondromalaciaExcessive pressure on the knee jointTendinitisOveruse and improper tracking of the patella
Patella Tracking
The VMO plays a critical role in the tracking of the patella, or kneecap, during knee movement. Proper functioning of the VMO ensures that the patella moves fluidly within its groove on the femur. If the VMO is weak, the patella may shift away from its normal path, leading to discomfort and potential injury [2].
Strengthening the VMO can help correct mal-tracking issues. When the VMO is activated correctly, it pulls the patella medially (toward the center of the body) and stabilizes its movement. This alignment is particularly important during activities that involve bending and straightening of the knee, such as squatting, running, and climbing stairs.
For those who experience issues like a stabbing pain in the knee cap or wish to improve their knee stability, focusing on the VMO and implementing targeted exercises can prove highly beneficial. Strengthening the teardrop muscle not only enhances aesthetic appeal but also promotes better performance in athletic endeavors and everyday activities.
VMO Weakness and Knee Pain
The vastus medialis obliquus (VMO) muscle plays a critical role in knee health. Weakness in this muscle is closely linked to various knee pain conditions, most notably patellofemoral pain syndrome. This syndrome involves pain around the kneecap and can severely impact mobility and quality of life.
Link to Patellofemoral Pain Syndrome
Patellofemoral pain syndrome (PFPS) is commonly associated with weakness in the VMO. This weakness leads to mal-tracking of the patella, which can increase stress on the knee joint. Research indicates that the specific training of the VMO is crucial for maintaining proper patellar positioning and limiting knee injuries. Misfiring or fatigue of the VMO can exacerbate issues by causing the patella to track incorrectly, contributing to conditions such as chondromalacia and anterior cruciate ligament (ACL) injuries.
The following table summarizes the potential injuries related to VMO weakness:

Potential Injuries
Inadequate strength in the VMO can lead to a higher risk of knee instability and various injuries. Injuries may manifest as difficulty in walking, navigating stairs, or performing weight-bearing activities. Running and jumping can particularly strain the VMO, increasing the likelihood of strains or tears, as well as potential nerve and connective tissue damage.
Recognizing the importance of the VMO in knee health is essential for understanding knee pain. Proper training and rehabilitation strategies can help address VMO weaknesses, thereby reducing the risk of patellofemoral pain syndrome and other associated injuries.

Assessing VMO Function
Effectively evaluating the vastus medialis obliquus (VMO) is important for understanding its functionality and performance in knee stability. Various methods can be employed to assess the VMO, including electromyography and targeted rehabilitation strategies.
Electromyography Evaluation
Electromyography (EMG) is a valuable diagnostic tool that can be used to assess the electrical activity of the VMO muscle. This technique helps in detecting abnormalities, weakness, or fatigue, which can be crucial for establishing appropriate rehabilitative plans aimed at correcting issues and preventing injuries [1].
EMG works by placing electrodes on the skin surface over the muscle of interest, allowing for the recording of electrical impulses during muscle contraction. The data collected can provide insights into the biomechanics of knee movement and highlight any dysfunction in the VMO.
