Sharply dissect the quadriceps fascia off the vastus lateralis muscle laterally to its inclusion with the iliotibial band.
It has been proposed that an imbalance of the vastus medialis oblique (VMO)/vastus lateralis (VL) muscle activities leads to excessive lateral tracking of the patella and rubbing of the lateral femoral condyle, which causes increased articular surface stress and induces pain.
In relation to the vastus lateralis, there was no significant difference in neuromuscular demand between BHT and squat exercises (Contreras et al., 2015).
The medial lip gives origin to vastus medialis and lateral lip gives origin to vastus lateralis.
Finnegan (1978:26) defines the vastus notch as "a small notch ...
The involvement of the vasti muscles (vastus lateralis, vastus intermedius, and vastus medialis), while sparing the rectus femoris, was remarkable.
These risk factors include excessive hip adduction and internal rotation during dynamic tasks (e.g., running and landing from a jump), weak or tight quadriceps, greater vertical peak force to the lateral heel and second and third metatarsals during gait, delayed activation of the vastus medialis obliquus compared with the vastus lateral (identifiable with a patellar tendon tap or rocking back on the heels), and increased knee-abduction impulses and moments during running and landing activities.
Morphological Analysis of Articularis Genus and Involvement in Muscle Synchronicity with Vastus Intermedius
Light microscopy of a vastus lateralis biopsy demonstrated ovoid organisms either free in the endomysium, within the myofiber sarcoplasm, or within macrophages in myofibers (Figure 1).
Work-up included an MRI that showed focal inflammation of the vastus medialis muscle, particularly in the distal third, but a biopsy found no bacterial growth, nor was there any bacterial or fungal infection found in fluid drawn from the knee.
Most published studies have assessed the reliability of EMG for measuring muscle activity of the trunk in patients with lower back pain (Dankaerts, O'Sullivan, Burnett, Straker, & Danneels, 2004) or lower limb muscles, such as vastus medialis obliquus (VMO), in patients with knee disorders (Worrell, Crisp, & LaRosa, 1998).
