Background There is controversy regarding the relationship between patellofemoral pain syndrome (PFPS) and insufficiency of the vastus medialis obliquus (VMO). The conventional clinical practice of VMO strengthening for PFPS has been challenged for lack of evidence. The purpose of this study was to observe the difference in sonographic findings of the VMO between patients with PFPS and healthy adults. Hypothesis The morphological characteristics of the VMO are different between patients with… 

Figures and Tables from this paper

Ultrasound investigation of vastus medialis oblique muscle architecture: An in vivo study
TLDR
The overlap in fiber angle values between healthy and pathological knees suggests that the cause of PFPS is multifactorial, and an individual's VMO architecture may be affected by their physical activity level, which could have important implications for PFPS.
Vastus Medialis Obliquus Atrophy
TLDR
The results of this study do show that atrophy of the VMO is a contributing factor in PFPS, and longitudinal, prospective studies are needed to establish the cause-effect relation of VMO atrophy and PFPS.
Vastus Medialis Obliquus Muscle Morphology in Primary and Recurrent Lateral Patellar Instability
TLDR
No significant difference was found with respect to all measured VMO parameters between primary dislocation, recurrent dislocated, and control subjects with a trend noted for only the V MO cross-sectional area and the VMO muscle-fiber angulation.
Selective Atrophy of the Vastus Medialis: Does It Exist in Women With Nontraumatic Patellofemoral Pain?
TLDR
The findings do not support the concept of preferential atrophy of the VM or generalized quadriceps atrophy in women with nontraumatic PFP.
Atrophy of the Quadriceps Is Not Isolated to the Vastus Medialis Oblique in Individuals With Patellofemoral Pain.
TLDR
Atrophy of all portions of the quadriceps muscles is present in the affected limb of people with unilateral PFP, and selective atrophy of the VMO relative to the vastus lateralis was not identified in people with PFP.
An investigation into the architecture of the vastus medialis oblique muscle in athletic and sedentary individuals: An in vivo ultrasound study
There is thought to be a relationship between the vastus medialis oblique muscle (VMO) and patellofemoral pain syndrome (PFPS), a condition that has a high prevalence in young athletic individuals.
Shear wave elastography properties of vastus lateralis and vastus medialis obliquus muscles in normal subjects and female patients with patellofemoral pain syndrome
TLDR
A significant VMO weakness is found, and this method may provide quantitative data that might influence the diagnosis of muscle weakness, in female patients with patellofemoral pain syndrome.
Effect of Static Knee Joint Flexion on Vastus Medialis Obliquus Fiber Angle in Patellofemoral Pain Syndrome: An Ultrasonographic Study.
TLDR
The lower angle of the vastus medialis obliquus fiber in those with patellofemoral pain syndrome implicitly suggests that vastus medicalis ob liquus dysfunction may exist, and this study investigates whether there was an ultrasonographic change by flexing the knee joint by means of ultrasonography.
Dose atrophy of vastus medialis obliquus and vastus lateralis exist in patients with patellofemoral pain syndrome
TLDR
The rationale for the use of general quadriceps exercise combined with vastus medialis obliquus strengthening exercise as part of the rehabilitation programme for the patients with patellofemoral pain syndrome is supported.

Association between sonographic morphology of vastus medialis obliquus and patellar alignment in patients with patellofemoral pain syndrome.
TLDR
This study showed that some aspects of VMO morphology, measured in full knee extension with the quadriceps relaxed, were associated with patellar alignment measured with the knee at 45 degrees of flexion, and whether or not V MO morphology serves as a predictor of patella alignment with the knees extended should be the focus of future investigations.
The vastus medialis oblique muscle and its relationship to patellofemoral joint deterioration in human cadavers.
TLDR
The results of this study do not support the premise that a more distal insertion of the VMO onto the patella of theVMO will have any effect on the presence or severity of PFJD.
Comparison of Vastus Medialis Obliquus:Vastus Lateralis Muscle Integrated Electromyographic Ratios Between Healthy Subjects and Patients with Patellofemoral Pain
TLDR
Patients with PFP may have abnormal VMO:VL activation patterns, and isotonic quadriceps femoris muscle exercise may elicit more favorable muscle activation patterns than isometric exercise for patients with PFA, according to an analysis of variance for repeated measures.
Role of the Vastus Medialis Obliquus in Repositioning the Patella
TLDR
Vastus medialis obliquus muscle function is important to consider in the rehabilitation of patients with patellofemoral pain syndrome, especially those with extreme patellar tilt and lateral shift malalignments.
Identification of individuals with patellofemoral pain whose symptoms improved after a combined program of foot orthosis use and modified activity: a preliminary investigation.
TLDR
Patients with patellofemoral pain syndrome who have forefoot valgus alignment of 2 degrees, passive great toe extension of 78 degrees, or navicular drop of 3 mm are most likely to respond favorably to initial intervention with an off-the-shelf foot orthosis and instruction in activity modification.
Effect of the vastus medialis obliquus on the patellofemoral joint
TLDR
The findings do not support the hypothesis of dominant centralizing effect of VMO on the patella in extension, but the effect of the VMO may be more clearly demonstrated by measuring PTA in both QC and QU positions.
Patellar stabilization: a quantitative evaluation of the vastus medialis obliquus muscle.
TLDR
The quantitative description of the VMO provided by this study will facilitate future efforts to accurately model the physiologic function of thev vastus medialis obliquus in cadaveric investigations on patellofemoral mechanics.
Structural parameters of the vastus medialis muscle
TLDR
The results of the study did not support the hypothesis that the oblique portion (VMO) of the vastus medialis muscle (VM) is anatomically positioned to function primarily as an active medial stabilizer of the patella.
Vastus medialis oblique/vastus lateralis muscle activity ratios for selected exercises in persons with and without patellofemoral pain syndrome.
TLDR
The results suggest that neither exercises purported to selectively activate VMO activity nor patellar taping improve the VMO/VL ratio over similar exercises.
The measurement of patellar alignment in patellofemoral pain syndrome: are we confusing assumptions with evidence?

TLDR
It is concluded that many of the beliefs of the clinical community with regard to the existence and measurement of patellar malalignment in patellofemoral pain syndrome may be based largely on assumptions and not on evidence.
